Dubond’s Hydro Coat is one pack, flexible, cement-based capillary waterproofing with carbonation inhibiting properties. It adheres to all types of surface which provides a solution to leakage, seepage or ingress of water / moisture in concrete by sealing capillaries and shrinkage cracks in both positive and negative side of the structure. Hydro coat penetrates into pores of substrate by capillary action and is channelled to the lower depths of concrete by inherent moisture therein, including those occurring even in the smallest pores and capillaries. Hydro Coat reacts with moisture and creates a continuous barrier of insoluble minerals as the product consists of high strength binders, selected silicon / quartz mineral charges with synthetic fibers and specific additives. The capillaries are permanently blocked to the passage of water. However, vapour may ass through allowing structure to breathe. Rate and penetration of minerals depends on presence of moisture, free lime and density of concrete.

Areas of Application
Advantages
How to UseThe recommended dosage rate will vary between 10-30 L /? ? of concrete, depending on the severity of the corrosion environment. In absence of a specified dosage rate, please contact your local Dubond representative. Adjust water content accordingly. Duplast CI may accelerate the setting time. In order to prevent slump loss or finishing characteristics, a set retarding admixture, like Duplast , may be required, especially in warm weather application. The full accelerating effect of Duplast CI may be used for cold weather concreting.
MixingMeasure the required quantity manually or by automated dispenser. Add Duplast CI directly into the freshly mixed concrete at the end of the batching cycle. When used in combination with other admixtures, care must be taken to dispense each admixture separately into the mix. Mix water adjustment is necessary to account for the water in Duplast CI and thus, maintain the required water/cementitious ratio. The batch water must be adjusted by reducing 0.839 kg of water per Liter of Duplast CI.
CompatibilityDuplast CI can be used with Portland cements compliant with ASTM, AASHTO or CRD specifications. It can be used in combination with other Dubond admixtures water reducers, super plasticizers, set retarders and air entrainment agents.

Duplast WRP is a chloride free water reducing admixture, is is based on selected sugarreduced lignosulphonates. It is supplied as a brown solution which instantly disperses in water. Duplast WRP disperses the fine particles in the concrete mix, enabling the water content of the concrete to perform more effectively and improving the consistency of the concrete. This produces higher levels of workability for the same water content, allowing benefits such as water reduction and increased strengths to be taken.
Areas of ApplicationTo improve the effectiveness of the water content of a concrete mix. Higher dosages provide effective means of reducing concrete permeability and thereby reducing water penetration.
AdvantagesAllows specified strength grades to be met at reduced cement content or increased workability. Water reduction significantly improves compressive strengths at all ages and enhances durability through the production of low permeability concrete. Minimizes the risk of segregation and bleeding and assists in the production of a dense, close textured surface, improving durability. Chloride free, safe for use in prestressed and reinforced
Typical PropertiesDuplast WPR conforms to IS: 9103-1999. It also complies with IS: 2645: 2003 as an integral waterproofing compound and ASTM C494 Type A as a normal water reducing admixture
Effect of over dosageAn overdose of double the intended amount of Duplast WPR will result in an increase in retardation as compared to that normally obtained at the intended dosage. This effect is found with most water reducing admixtures although the degree may vary. Retardation is affected by factors other than the admixture depending on the mix details and conditions involved. Trials to assess the effects in a particular mix are strongly recommended if this aspect is of particular importance, provided that adequate curing is maintained. The ultimate strength of the concrete will not be impaired by increased retardation and will generally be increased. The effects of overdosing will be further increased if sulphate resisting cement or cement replacement materials are used. Over dosage may also cause increased air entrainment, which will tend to reduce strength. The degree of this effect will depend on the particular mix design and overdose level. An overdose will tend to increase the plasticizing effect of the admixture. As concrete is normally batched to target workability, increased plasticizing will allow an increasing ultimate strength and partially or fully offsetting the effect of any increased air entrainment. If no increase in water reduction is taken and a significant rise in workability is allowed the chance of segregation may be higher. Increased initial workability will tend to extend the working life of the concrete, which will delay finishing and stiffening time to some extent.
DosageThe optimum dosage of Duplast WPR to meet specific requirements should always be determined by trials using the materials and conditions that will be experienced in use. This allows the optimisation of admixture dosage and mix design and provides a complete assessment of the concrete mix. A starting point for such trials is to use a dosage within the normal typical range of 0.20 to 0.50 litres / 100kg of cementitious material, including PFA, GGBFS and microsilica.
CompatibilityDuplast WPR is compatible with other Dubond admixtures in the same concrete mix. All admixtures should be added to the concrete separately and must not be mixed together prior to addition. The performance of concrete containing more than one admixture should be assessed by the trial mix procedure recommended in this data sheet to ensure that, effects such as unwanted retardation do not occur. Duplast WPR is suitable for use with all types of ordinary Portland cements and cement replacement materials such as PFA, GGBFS and micro silica.Reducing water permeability (‘waterproofing’) One of the most effective means by which the water permeability of a concrete mix can be reduced is to make a large reduction in water-cement ratio. Duplast WPR can be used to provide such a reduction and to produce a concrete with the benefits of low permeability.
StorageDuplast WPR has a minimum shelf life of 12 months provided the temperature is kept within the range of 20º C to 40º C.
Safety and PrecautionsDuplast WPR does not fall into the hazard classifications. However, it should not be swallowed or allowed to come into contact with the skin and eyes. Suitable protective gloves and goggles should be worn. Splashes on the skin should be removed with water. In case of contact with the eyes, it should be rinsed immediately with plenty of ater and medical advice sought immediately. If swallowed medical attention sought immediately - Vomiting should not be induced.

Dubond's Duplast CC-WB is a ready to use, liquid membrane curing compound based on selected grades of low viscosity paraffin wax emulsion which incorporates a special reactive emulsion breaking system. This system ensures that the emulsion breaks down to form a non-penetrating continuous film immediately upon contact with a cementitious surface. This impervious film permits more efficient cement hydration, thus reducing shrinkage and increasing durability. Once formed, the membrane will remain on the concrete surface until eventually broken down and eroded by natural weathering. Where it is required to apply a further treatment to such concrete surface, it may be necessary to remove the remaining membrane after curing, by wire brushing or other mechanical means.
Uses
Advantages

DUPUMP is a powder packed in pre-weighed pouches to be mixed with water at site. It is a unique compound of high performance components, which offers superlative cost reductions by saving time and protecting pump and pipe line. DUPUMP eases hydraulic pressure in the pump and pipe line and optimizes pump capacity when using “sticky” concrete mixes. DUPUMP is environment friendly and is not harmful to concrete, like chlorides or active air entraining substances.
UsesA knowledgeable operator and DUPUMP is a great combination. Operators dislike pump blockages as much you do. Once they understand how well Dupump works, they will insist on using it every time. Thus, the number of pump blockages will be minimized. The need for fewer expensive elbows and pipe is like money in the bank. Pump the tough jobs. DUPUMP used as a pump aid lets you do jobs that others have failed on. When a construction manager sees that you can pump a job that others cannot, you gain a customer. Faster priming means less time on job and more jobs, i.e., more revenue per day

Areas of Application
In the high alkalinity of concrete, reinforcing steel builds up a natural passivation layer. This layer protects the steel from corrosion. This passive ferric oxide layer however can be damaged by the presence of chlorides and combined with the presence of moisture and oxygen which will lead to corrosion of the steel.
Duplast CI will help oxidize the steel to form ferric oxide, which resists chloride attack. This reduces the areas of ferrous oxide ions that are susceptible to attack by chlorides. Ferrous oxide creates a ferrous oxide complex (rust), if attacked by chlorides. In the presence of these chlorides, rust continues to generate in these areas (corrosion pits) and ultimately leads to staining, cracking and spalling of the concrete
Duplast CI fortifies the ferric oxide passivating layer prior to the penetration of chlorides. The nitrite ions in Duplast CI will convert ferrous oxide to more resistant ferric oxide, thereby protecting the steel reinforcement from corroding.
Advantages
Duplast CI is recommended for conventional steel reinforcement as well as pre- stressed or posttensioned concrete that will be exposed to chlorides from marine environments or deicing salts. Duplast CI will extend the service life of structures by effectively inhibiting corrosion, in areas such as parking garage decks and support structures, bridge decks, marine structures and many others. Duplast CImay also is used in concrete elements where chlorides are added initially to the concrete mix. Duplast CI is a corrosion-inhibiting admixture that provides protection against corrosion in reinforced concrete structures. Duplast CI:
The recommended dosage rate will vary between 10-30 L /? ? of concrete, depending on the severity of the corrosion environment. In absence of a specified dosage rate, please contact your local Dubond representative. Adjust water content accordingly. Duplast CI may accelerate the setting time. In order to prevent slump loss or finishing characteristics, a set retarding admixture, like Duplast , may be required, especially in warm weather application. The full accelerating effect of Duplast CI may be used for cold weather concreting.

MixingMeasure the required quantity manually or by automated dispenser. Add Duplast CI directly into the freshly mixed concrete at the end of the batching cycle. When used in combination with other admixtures, care must be taken to dispense each admixture separately into the mix. Mix water adjustment is necessary to account for the water in Duplast CI and thus, maintain the required water/cementitious ratio. The batch water must be adjusted by reducing 0.839 kg of water per Liter of Duplast CI.
Compatibility
Duplast CI can be used with Portland cements compliant with ASTM, AASHTO or CRD specifications. It can be used in combination with other Dubond admixtures water reducers, super plasticizers, set retarders and air entrainment agents. Admixtures have to be added separately to the concrete mix in order to deliver the results required. Duplast CI may slightly reduce the entrained air content and a higher dosage of the air entrainment agent may be required.
Duplast CI should be stored above 5°C. If frozen, thaw out and agitate thoroughly to return to normal state before use. Shelf life when stored in dry warehouse conditions between 10°C - 27°C is two years minimum.

To improve the effectiveness of the water content of a concrete mix.
Higher dosages provide effective means of reducing concrete permeability and thereby reducing water penetration.
Advantages
Allows specified strength grades to be met at reduced cement content or increased workability.
Chloride free, safe for use in prestressed and reinforced.
Typical PropertiesDuplast WPR conforms to IS: 9103-1999. It also complies with IS: 2645: 2003 as an integral waterproofing compound and ASTM C494 Type A as a normal water reducing admixture.
Effect of over dosage
An overdose of double the intended amount of Duplast WPR will result in an increase in retardation as compared to that normally obtained at the intended dosage. This effect is found with most water reducing admixtures although the degree may vary. Retardation is affected by factors other than the admixture depending on the mix details and conditions involved. Trials to assess the effects in a particular mix are strongly recommended if this aspect is of particular importance, provided that adequate curing is maintained. The ultimate strength of the concrete will not be impaired by increased retardation and will generally be increased. The effects of overdosing will be further increased if sulphate resisting cement or cement replacement materials are used. Over dosage may also cause increased air entrainment, which will tend to reduce strength. The degree of this effect will depend on the particular mix design and overdose level. An overdose will tend to increase the plasticizing effect of the admixture. As concrete is normally batched to target workability, increased plasticizing will allow an increasing ultimate strength and partially or fully offsetting the effect of any increased air entrainment. If no increase in water reduction is taken and a significant rise in workability is allowed the chance of segregation may be higher. Increased initial workability will tend to extend the working life of the concrete, which will delay finishing and stiffening time to some extent.
DosageThe optimum dosage of Duplast WPR to meet specific requirements should always be determined by trials using the materials and conditions that will be experienced in use. This allows the optimisation of admixture dosage and mix design and provides a complete assessment of the concrete mix. A starting point for such trials is to use a dosage within the normal typical range of 0.20 to 0.50 litres / 100kg of cementitious material, including PFA, GGBFS and microsilica.
Duplast WPR is compatible with other Dubond admixtures in the same concrete mix. All admixtures should be added to the concrete separately and must not be mixed together prior to addition. The performance of concrete containing more than one admixture should be assessed by the trial mix procedure recommended in this data sheet to ensure that, effects such as unwanted retardation do not occur.
Duplast WPR is suitable for use with all types of ordinary Portland cements and cement replacement materials such as PFA, GGBFS and micro silica.

One of the most effective means by which the water permeability of a concrete mix can be reduced is to make a large reduction in water-cement ratio. Duplast WPR can be used to provide such a reduction and to produce a concrete with the benefits of low permeability.
Storage
Duplast WPR has a minimum shelf life of 12 months provided the temperature is kept within the range of 20º C to 40º C.
Surface Preparation
uplast WPR does not fall into the hazard classifications. However, it should not be swallowed or allowed to come into contact with the skin and eyes.
Suitable protective gloves and goggles should be worn. Splashes on the skin should be removed with water. In case of contact with the eyes, it should be rinsed immediately with plenty of water and medical advice sought immediately. If swallowed medical attention sought immediately - Vomiting should not be induced.

DUPUMP eases hydraulic pressure in the pump and pipe line and optimizes pump capacity when using “sticky” concrete mixes. DUPUMP is environment friendly and is not harmful to concrete, like chlorides or active air entraining substances.
A knowledgeable operator and DUPUMP is a great combination. Operators dislike pump blockages as much you do. Once they understand how well Dupump works, they will insist on using it every time. Thus, the number of pump blockages will be minimized. The need for fewer expensive elbows and pipe is like money in the bank.
Pump the tough jobs. DUPUMP used as a pump aid lets you do jobs that others have failed on. When a construction manager sees that you can pump a job that others cannot, you gain a customer.
Faster priming means less time on job and more jobs, i.e., more revenue per day.
Increases pump capacity – reduces pressure in concrete pump and pipes.
Clean and easy preparation of the primer.
In 5 minutes the equivalent primer is ready, as opposed to lugging sacks of sand and cement.
Ready – to – use in pre – weighed pouches of 210gms, which corresponds to the equivalent contents of 50-150 kg of cement.
Superior concrete pump capacity.
Minimizes wear and abrasion of concrete delivery pipes.
Outstanding time saving produces enhanced transport efficiency.
The risk of “stop” and “block” is reduced to virtually nil.
Add 1 pouch of 210gms DUPUMP to 25-30 litres of clean tap water and mix for 1-2 minutes. A sticky jelly texture will develop. Allow it to stand for 5-7 minutes. Add 120-150 litre of clean tap water. Now, pour Dupump slurry into the hopper. It will allow the slurry to be charged in the system ahead of the concrete. For better results, wetting of pipes before starting the priming of pipe.
It is better than using the old methods:

Duplast AIREX is designed to produce air entrainment in concrete mixes. It is used whenever compacted, durable concrete with resistance to frost action and effects of de- icing salt is required. It improves workability & reduces tendency of bleeding. It also reduces density of light weight blocks, without impairing strength. It gives increased durability to dense concrete blocks & because of entrained air; a reduction in material cost is achieved.
