TamCem 67 is a new generation superplasticiser for high early strength concrete. It contains state-of-the-art polycarboxylate ether polymers and is specially formulated to give high water reduction, enhanced workability and offers superior early age strength development. TamCem 67 specially designed for precast concrete applications. It is a non-chloride liquid admixture which has been formulated to comply with the requirements of EN 934-2 and ASTM C 494 for Type F high range water reducing/superplasticising admixtures. TamCem 67 is compatible with all cements meeting recognised international standards.
TamCem 67 is based on versatile polycarboxylate co-polymer technology. Its unique long chain molecular structure enhances the dispersion of cement particles, by means of steric hindrance, whereas conventional SNF and SMF based superplasticisers, will only undergo less powerful electrostatic repulsion. In addition to the polycarboxylate co-polymers, TamCem 67 also contains components capable of increasing the rate of early age hardening of the concrete at ambient and low temperatures.
