Concrete Demolition Principle

Concrete Demolition Principle
  • Min. Order (MOQ) 1000 Kilogram
  • Brand Name STONE CRACK SINO CRACK
  • EXPANSIVE POWDER WHITE GRAY
The principles applied in using Expansive Mortar are very much similar to those ones followed in traditional blasting techniques. As like for explosives, holes must be drilled to contain Expansive Mortar which must thoroughly be mixed with a measured quantity of water and poured into the holes. Few minutes after filling, a reaction of hydration is taking place generating heat and crystallizing and expanding while hardening. If hydration takes place under confinement, significant expansive pressure will result. Cracks will develop along the line of holes. A person who can deeply understand hydration reaction, Starvation and Expansion process become an expert in this product application. No need for detonator, ignition and certified explosive operators.

Principle Of Working

Principle Of Working

Expansive Mortar is being manufactured from burnt lime having high purity Calcium Oxide which has property of volumetric expansion on hydration reaction with water. The principles applied in using Expansive Mortar are very much similar to those ones followed in traditional blasting techniques. As like for explosives, holes must be drilled to contain Expansive Mortar which must thoroughly be mixed with a measured quantity of water and poured into the holes. Few minutes after filling, a reaction of hydration will takes place generating heat, crystallizing and expanding while hardening. If hydration takes place under confinement, significant expansive pressure will develop resulting cracks along the line of holes. A person who can deeply understand hydration reaction and Expansion process become an expert in this product application. No need for detonator, ignition and certified explosive operators.

Stone Crack Powder

Stone Crack Powder
  • Min. Order (MOQ) 5 Metric Ton
  • Brand Name Sino Crack
  • POWDER GRAY
We are offering stone cracking powder that is used in demolition of rock and concrete structures in dust and noise sensitive areas and places closed to inhabited areas, natural gas lines, pipelines, roadways or other areas where the use of explosive would generate significant safety risk.It is a non-explosive demolition agent used to demolish rock and concrete structures through eco-friendly procedure. It is a non-toxic and powdery material, which consists of oxides of calcium, silicon iron and aluminium. When it mixes with clear water (ph=6.57) and poured in drilled hole, it subjects to hydration reaction liberating heat energy and it swells while hardening creating a significant expansive pressureforce on the hole wall face at 600 psi of pressure. It is strong enough to split and fracture marble, granite, limestone, sand stone, concrete, reinforced concrete, virgin boulders ledge and piers etc without any sound and flying rock. Productive sca can be used where explosives are forbidden and extensively in granite industry to avoid unwanted cracks in the material. Use of explosives to split the big blocks highly prone to internal crack development which may leads to reject the material for exporting. So, replacing the explosives with productive sca will result in significant increase in productivity. advantages It does not make any noise, explode or generate fly rocks, vibration or toxic fumes. It is completely harmless and environment friendly. At the other side, explosives are less safe and pose the threat of premature explosion, misfire and fly rocks, posing a significant threat after the planned explosion and also chances for uneven cracking and internal crack development. So, usage of productive sca is very productive and safe. Usage of productive sca has become a common procedure in demolition in inner citied, other dust and noise sensitive areas. productive sca has also used when excavating rock, or demolishing concrete structures or components of concretes structures are closed to inhabited areas, natural gas lines, pipelines, roadways or other areas where the use of explosive would generate significant safety risk.

*Water mix ratio and ambient temperature are the most important variables in influencing the generation of expansive pressure. Advantages
  • Soundless Cracking
  • Unlike the existing method of demolition done by explosives or breaking equipment ‘Productive SCA’ quietly and gradually demolishes rock or concrete with its expansive stress (more than 30 N/mm2) caused by hydration reaction, so that Productive SCA does not cause any noise vibration fly rock dust and gas
  • Using ‘Productive SCA’ does not require a special license or meeting any legal regulations unlike explosives explosive agents etc therefore no qualified person for handing are required and the demolition can be easily performed
  • Neither capping with a bar is necessary after ‘Productive SCA’ mixed with water is poured into drilled holes in rock or concrete (except the hole angle of drilling is with negative slope)
  • ‘Productive SCA’ can demolish rock or concrete systematically and also demolition work in water is possible
  • High-efficiency demolitions
  • Since rock or concrete previously cracked with ‘Productive SCA’ is easily broken with breakers etc the amount of time required for breaking of rock or concrete can be remarkably reduced
Usage Procedure and Requirements
  • Drilling : The distance between the holes to be drilled depends on size of the holes and type of material to be cut (for Rock Material and Non-Reinforced Concrete of hole size 32-42 mm Dia. Holes mean distance should range 20-35mm for reinforced concrete mean distance should range from 15-25mm).
  • Mixing : Productive SCA is a powder that must be mixed thoroughly with clear water in a ratio of 30 % say 1.5-1-1.7 Lit for 5 Kg bag. We strongly insists the users to carry out a test in practical with various proportions to decide the correct proportion for better results. Gradually add the powder to water and stirring all the time to obtain a smooth lump of free mortar. Excessive water may delay the cracking process and less water may lead to starvation during reaction. Users are requested to follow the instructions mentioned on the bag.
  • Filling : Pour the Expansive Mortar within 5-10 min only. Stop leak out of productive SCA from horizontal holes with suitable means like sponge, for horizontal holes use thick mortar or cartridge type packages. For further information feel free to discuss with us.
  • Free Surface : It is one of the significant factors that play an important role in cracking process. As expansive pressure acts towards free surface, it is necessary to ensure free surface at least at one edge for a bottom free rock/boulder. if the rock/boulder is routed into the earth surface please contact us for the suitable hole design to demolish the big boulder/rock rooted inside the earth. We have dedicated geologists and rock engineers to serve you the best.
Cracking Mechanism After the mortar is poured into holes drilled in rocks or concrete, the expansive stress gradually increases with time, the material to be cracked undergoes a process of :
  • Crack initiation
  • Crack propagation
  • The increase of crack width
Therefore, this fracture mechanism is distinguished from a breakage by blasting. The mechanism by the expansive stress of “Productive SCA” is shown in Fig. 1. Cracks initiate from an inner surface of the hole, being caused by tensile stress at a right angle with the compressive stress which occurs by the expansive stress of being developed while hardening. The expansive stress continues even after the appearance of cracks, the cracks propagate and also new cracks initiate during the process. Usually, for a single hole, 2-4 cracks initiate and propagate. When a free surface exists, the crack, as shown in Fig. 2, is pushed apart mainly by the shear stress, and a secondary crack also arises from the bottom of the hole, running toward the free surface.

Non Explosive Rock Demolition Agent

Non Explosive Rock Demolition Agent
  • Min. Order (MOQ) 5 Metric Ton
  • Brand Name Sino Crack
  • Gray Powder
Non Explosive Rock Demolition Agents are commercial products that are an alternative to explosives and gas pressure blasting products in demolition, mining, and quarrying. To use non-explosive demolition agents in demolition or quarrying, holes are to be drilled on the base rock according to drilling pattern supplied. A thoroughly mixed non-explosive demolition agent and water is poured into the drill holes. Over the next few hours the slurry expands, cracking the rock in a pattern somewhat like the cracking that would occur from conventional explosives. Non-explosive demolition agents offer many advantages including that they are silent and do not produce vibration the way a conventional explosive would. In many countries these are available without restriction unlike explosives which are highly regulated. These agents are much safer than explosives, but it is important to follow directions closely in order to avoid steam blow outs during the first few hours after these materials are placed. In natural stone quarrying industry non explosive demolition chemical application termed as ever best method techno-economically because of its unique characteristics of application results. Accurate sizingdimensioning of blocksNo vibration hence No internal cracks & reduction in scrap.Cheapest method compared with other techniques like Wire-Saw Cutting.No supervision required once applied.Less skill and less man power.Multi task execution hence more productivity etc. Now a day in real estate development in urban and sub-urban cities non explosive demolition application become an essential activity due to safety risks in inhabitant areas, And this technology also being used in demolition of concrete structures like Turbine-Generator Foundations in Power Plants, Big size equipment foundations, Gas Pipe Lines Anchor blocks, Pile structures of Bridges, various concrete foundations etc.

Mixing

Expansive Mortar is a powder that must be mixed thoroughly with clear water in a ratio of 30 % (w/w) say 1.5-to-1.7 Lit for 5 Kg bag. We insist users to carry out a test in practical with various proportions from 1.5 to 1.7 Lit per 5 kgs (Most using proportion is 1.65 Lit/5Kg) to decide the correct proportion for better results. Gradually add the powder to water and stir all the time to obtain a smooth and LUMP-FREE mortar. Excessive water may delay the cracking process and less water may lead to starvation during reaction. Users are requested to follow the instructions mentioned on the bag.

 

Filling

After mix has been prepared it should be poured into the holes. as reaction starts quickly, pour the Expansive Mortar within 5-10 min after mixing. During filling do not maintain any delay in any particular hole Otherwise it may lead to non-homogeneous reaction resulting throw out of chemical. No Capping required. Do not keep any obstruction on Hole. For further information feel free to discuss with us.

Cracking Mechanism

After the mortar has poured into holes drilled on rock or concrete, the expansive stress gradually increases with time, the material to be cracked undergoes a process of:
  • Crack initiation
  • Crack propagation
  • The increase of crack width
The mechanism by the expansive stress of Productive SCA is shown in Fig. 1. Cracks initiate from an inner surface of the hole due to circumferential stress that develops during expansion process while hardening. The expansive stress continues even after the appearance of cracks, the cracks propagate and also new cracks initiate during the process. Usually, For a single hole, 2-4 cracks initiate and propagate either towards nearest free surface or nearest hole. When a free surface exists, the crack, as shown in Fig. 2, is pushed apart mainly by the shear stress, and a secondary crack also arises from the bottom of the hole, running toward the free surface. Please note during the initial reaction process (i.e., 30-60mis) there are chances for blow-shot releasing gases evolved in the hydration reaction. So, during that period we insists workers to stay away at least 10 mts from Job place. Peeping onto the hole strictly prohibited.
