HYPERCRETE R is a polycarboxylic ether-based advanced superplasticizer which is specially developed for high-fluidity Concrete applications. The product could be used for virtually any type of ready-mix concreting where slump retention is important.
HYPERCRETE R is compatible with all types of cement and other mineral admixtures. HYPERCRETE R is free of chlorides and meets the requirements of ASTM C494Type G, BS 507 5, BSEN934-2
Sulfonic groups of Naphthalene or Melamine based admixtures which adsorbed onto 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 a strong repulsive force which in turn increases the workability of the cement paste.

ADVANTAGES
- Make fluid concrete
- Self Compacting Concrete
- Longer slump retention.
- 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.
- Helps in hot weather concreting.
COMPATIBILITY
HYPERCRETE R 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 R is compatible
with lignosulphonate based admixtures and not compatible with naphthalene admixtures.
DIRECTIONS FOR USE
HYPERCRETE R 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 a full quantity of water prior to being added to the dry mix of concrete. Agitate the liquid well prior to
use.
DOSAGE
The optimum dosage should be determined by site trials with particular raw materials. As a guide HYPERCRETE R is normally used at a dosage 600ml to 1700ml per 100kg of cement.
However, for specific requirements dosages outside the above could be used.
PACKAGING AND STORAGE
HYPERCRETE R is supplied in 205 L drums, 1000 L IBC tanks or in bulks tankers of 2400L
HYPERCRETE R has a shelf life of 12 months in its unopened drums. All admixtures should be storedunder shade.
SAFETY OF HANDLING
HYPERCRETE R does not contain any hazardous chemicals and nontoxic. But it is recommended that safety glows are used in handling the product.
