Concrete sizing reducer is a kind of comprehensive concrete admixture compounded by macromolecular surfactant, also known as synergist. The main action mechanism of the sizing reducer is to realize the efficient dispersion of cement clinker, reduce the occurrence of mineral agglomeration, provide a particle hydration environment, accelerate the cement hydration process, and improve the overall slurry volume of concrete by improving the concrete workability, so as to reduce the cement consumption and ensure the later strength development of concrete.

Polycarboxylic acid water reducer is extremely sensitive to the adsorptive materials (mud or stone powder) in concrete. When the mud or powder content in the concrete system is high, the polycarboxylic acid water reducer shows insufficient water reduction rate, large slump loss and other phenomena, which have a great impact on concrete transportation, working state and strength.

Clay, mineral or porous materials have a certain adsorption on polycarboxylic acid water reducer, and the adsorption capacity is stronger than that of cement particles on polycarboxylic acid water reducer. This competitive adsorption reduces the effective content of polycarboxylic acid water reducer, thereby reducing the dispersion efficiency of polycarboxylic acid water reducer, causing loss of its performance. Therefore, how to solve the problem that polycarboxylic acid water reducer is sensitive to a large number of adsorptive materials in sand and gravel has become a hot issue to be solved in the additive industry.
