Abstract

The invention provides a compounding method for a YMS-1 type polycarboxylate superplasticizer. The compounding method is characterized in that a polycarboxylate superplasticizer is used as a basic material and is compounded with an additional component which is a retarder or an antifoaming agent. The invention has the following beneficial effects: the problem of reduction in strength caused by changes of raw materials and proportion of concrete is overcome; effects of compounding components are fully superposed, and inhibition reaction is reduced to a greatest extent.

Description

technical field [0001] The invention belongs to the technical field of concrete admixtures, and in particular relates to a compounding method of a YMS-1 type polycarboxylate water reducer. Background technique [0002] With the commercialization of concrete, the use of concrete admixtures has become an indispensable fifth component of modern concrete; polycarboxylate-based water reducers are synthesized by molecular design methods according to the mechanism of action of water reducers on cement. The molecular chain of the type structure solves the common problems of traditional water reducing agents such as large slump loss over time, relatively low water reducing rate, and harm to the environment from the molecular structure. Therefore, polycarboxylate superplasticizers will surely become an important direction for the development of green concrete superplasticizers in the 21st century. [0003] The current product has disadvantages: the effect of the compound components o...
