Water Reducer

Water reducer mainly is used for cement in construction field. Used for and widely for self-cured, vapor-cured concrete and its formulations. At the early stageof application, extremely prominent effects are shown. As the result, the modulus and site utilization can be drastically, the procedure of vapor cure is omitted in peak-heatsummer days. Statistically 40-60 metric tons of coal will be preserved when a metric ton of the material is consumed.The new raw material is researched and produced by ourselves, which is mainly used in theproduction of polycarboxylate superplasticizer products.

Remarkable plasticity: as a condition of blending where amount of cement and collapsibility are fixed aforehand, mixing water can be decreased by 18-28% when it is admised with reinforced concrete at 0.5-1.0%. Ststistically, compression strendth on the 1st day, the 3rd day and the 28th day after single application is increased by 60-90% and 25-60% respectively when it is added at standard blend dosage. As the result, compression strength, tensile strength, bucking strgth and modulus of elasticity will be improved to some extent.
