ECMAS HP 904
ECMAS HP 904 is a stated of the art Hyperplasticiser Based on Specially Selected and modified Polycarboxylic ether. The product has been primarily developed for applications in high performance concrete where the highest durability and performance is required. ECAMS HP 904 is free of chloride. It provides excellent water reduction with good workability retention allowing production and placing of high quality concrete. Hence, it is used for the production of pre-cast , pre- stressed concrete and SCC. ECMAS HP 904 is Compatible with all types of cements and Mineral Admixtures Like PFA, GGBS, Metakaolin , Micro-silica, Alccofine etc.
ECMAS HP 904 is used in high early and ultimate strength concrete; high performance concrete with durability; Concretes with high fluidity. It is used wherever you need lower permeability and long durability; low water binder ratio. Eliminate/Reduce to Steam Curing.
ECMAS HP 904 is used generally at a dosage of range 0.2% to 1.4% by weight of cement. The exact dosage is determined by carefully done trials at project site labs/ready mix concrete plant labs to suit the requirements with locally available cements/ingredients. The trials also are done to check properties both in fresh and hardened state.
ECMAS HP 904 is recommended to be added on to wet mix and mixed for 2-3 minutes to get proper dispersion and optimum performance. The optimum time of mixing again depends on the mixer capacity/efficiency etc. ECMAS does not recommend any other different chemical admixtures to be used in conjunction with ECMAS HP 904 unless otherwise, such an event is approved with proper / prior trials done in consultation with ECMAS.
