ECMAS HP 901

ECMAS HP 901 is a state of the art, hyper-plasticiser based on specially selected and modified Poly Carboxylic Ethers, designed to yield exceptional performance. It provides excellent water reduction coupled with good workability retention allowing production and placing of high quality concrete, without any problems of set time retardations. Hence, it can be used for the production of various grades of concretes. ECMAS HP 901 can also be used in manufacturing of SCC*. It can be used in different varieties of concretes including those that contain mineral admixtures like PFA, GGBS, Metakaolin, Micro Silica etc.

Uses

ECMAS HP 901 is used generally at a dosage of range 0.25% to 1.5% 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 901 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 901 unless otherwise, such an event is approved with proper / prior trials done in consultation with ECMAS.

Application

ECMAS HP 901 is used for high-strength concretes and high performance concretes. It is also used for concretes with high fluidity and concretes for congested reinforcement applications and SCC*.
