HYPERCRETE HS is polycarboxylic either based advanced superplasticizer which is specially developed for precast concrete applications.Hence the product could be used for virtually any type of concreting where high early strength is important. HYPERCRETE HS is compatible with all types of cements and other mineral admixtures.
HYPERCRETE HS is free of chlorides and meets the requirements of ASTM C494Type A & F, BS507 5, BSEN 934-2
Sulfonic groups of Naphthalene or Melamine based admixtures which adsorbed on to the cement particles induce a negative charge and repulse each other and increase the workability.With a similar mechanism, but unlike sulfonic
groups, the lateral chains of the main polymer of polycarboxylic ether induce a steric hindrance with strong repulsive force which in turn increases the workability of the cement paste.

ADVANTAGES
- Can make fluid concrete for SCC.
- Achieves high early strength
- No bleeding & segregation.
- Reduce shrinkage and creep.
- Reduces porosity and hence permeability of hardened concrete.
- Rheoplasticity leads to a densely compacted durable concrete at hardened state.
- Substantially reduce the placement cost and the time
- Esthetically attractive surface texture and sound finish.
- Very high water reduction and thereby low permeability and shrinkage.
- Less pumping pressure and ease of pumping.
COMPATIBILITY
HYPERCRETE HS is compatible with mineral admixtures such as Silica Fumes, Fly Ash, GGBFS and chemical admixtures such as waterproofing admixture, Air entraining agents and corrosion inhibiting agents.HYPERCRETE HS is compatible
with lignosulphonate based admixtures and not compatible with naphthalene admixtures.
DIRECTIONS FOR USE
HYPERCRETE HS should be dispensed into the fresh concrete or with the final quantity of mixing water. It should not come into contact with dry cement or other admixture until they are mixed in the concrete batch. Also it can be fully dispersed with full quantity of water prior to be added to the dry mix of concrete. Agitaty the liquid well prior to use.
DOSAGE
The optimum dosage should be determined by site trials with particular raw materials. As a guide HYPERCRETE HS is normally used at a dosage 500ml to 1500ml per 100kg of cement. However for specific requirements dosages outside the above could be used.
PACKAGING AND STORAGE
HYPERCRETE HS is supplied in 205 L drums, 1000 L IBC tanks or in bulks tankers of 2400L
HYPERCRETE HS has a shelf life of 12 months in its unopened drums. All admixtures should be stored under shade.
SAFETY OF HANDLING
HYPERCRETE HS does not contain any hazardous chemicals and nontoxic. But it is recommended that safety glows are used in handling the product.
