SIXIN defoamer 14th, Nov
The water reducer refers to the admixture which can reduce the water consumption of mixing and increase the concrete strength under the condition of constant workability of concrete and the amount of cement, or to save the the amount of cement under the condition of constant workability and strength.
Water reducer is a use of surfactants and is easily foamed in the stirring process. Water reducer is generally strong alkaline. The addition method of defoamer is different, first it’s added directly, in the water reducer ( i.e. internal additive), second it’s added when the water reducer and concrete are mixed(i.e.admixture). The first method requires good dispersion.
