GEEKAYPLAST ACL reduces the setting and hardening time of concrete and also increases the compressive strength at 7days. COMPOSITION &CONDITIONS 0.8% to 2% of GEEKAYPLAST ACL by weight of cement. Maximum dosage can be increased depending on the required early setting and hardening. The optimum dosage should be determined by site or laboratory tests with the particular concrete mix.
