Plasticiser & Set Accelerator

About Plasticiser & Set Accelerator

CETEX- Set Accelerator (SA) when added in thecementitious mixture, it decreases the set time of the mix. CETEX-SA isused in production of concrete whereearly set is required. It is ideal for sprayed or pumped concrete/mortarmix like in shotcrete / guniting and ready mix concrete. It is also suitablefor concrete where high early strength is required or formwork has to beremoved early, for example reinforced pre cast. It complies with ASTM-C-494Type C, IS- 9103.MECHANISMCETEX-SAincreasesthe chemical reaction of cement and water, thereby accelerating the rate ofsetting and early gain in the strength. It also results in overall strength ofconcrete. ADVANTAGES Faster hydration process results in faster hardening and early higher strength of fresh mix. It can be used as anti-freeze admixture for winter concreting. It can also be used to counteract retardation due to superplasticiser. It reduces rebound loss in shotcrete / guniting. It allows early shifting of pre-cast elements. It reduces/eliminates steam curing cost of pre-cast elements. It does not contain chlorides; hence it does not corrode the steel structure.

However, fieldtrials should be conducted to determine the optimum dosage to achieve therequired condition DIRECTION OF USECETEX-SAshould beadded to the concrete mix during the mixing cycle after addition of water. Neveradd the admixture to the dry mix.PACKING CETEX-SAisavailable in 70 or 300 kg pack. Store in frost-free condition away fromsunlight or extreme heat. For best result, use within one year.
