Hardening Accelerator Admixture

Listing ID #2792677

HA2-356 increases the early strength of concrete and mortar without affecting the initial workability and final strength.
Uses :

Especially suitable for any application where fast early strength development plays a major role, or is of crucial importance within 6 to 24 hours. HA2-356 can be used for the following applications :

• Pre cast concrete
• Site batched conrete
• Ready mixed concrete where early de-moulding is essential
• Slip-form concrete
• In cold ambient temperatures to achieve sufficient strength gain

Advantages
Provides the following advantages through accelerated hardening of the concrete :

• When applied wiht a plasticizer it will not change the fresh concrete properties produced by plasticizer
• Faster turnaround of form work in pre cast applications
• Early release of stressing cables in pre stressed concrete structures
• Reduced or eliminated heat or steam curing
• Fast construction processes and early load bearing capacity.
• Does not contain chloride.

Appearance : Pale yellow to Reddish colour
Chemical Base : Aqueous solution of inorganic salts
Relative Density : 1.17 at 25^oC
Packaging : HA2-356 is Available in 230 kg Non Returnable Drums.
Storage & Shelt Life
12 months from date of production if stored properly in undamaged unopened, original sealed packaging, in dry conditions at temperatures between +5^oC and +25^oC. Protect direct sunlight and frost.
Dosage
050-2.0% by weight of cement/ Higher dosage may be used. Exact dosage rates are however dependant on the type of effect sought, quality of cement and aggregates, water/cement ratio and ambient temperature. Actual dosage to be finalised on the basis of site trials.
Application Conditions Instructions for Use
HA2-356 should be added separately to the freshly mixed concrete. After addition, further mixing of at-least 1 minute should take place per cubic metre of concrete.
