Abstract

Polycarboxylate superplasticizers (PCE) with different molecular structures were prepared through radical polymerization using monomers with varying molecular weights, and their molecular structures were characterized by gel permeation chromatography. The adsorption properties of PCE on the surface of desert sand were studied using a total organic carbon analyzer, and mortar fluidity tests were conducted. The results showed that PCE with a molecular weight in the range of 30,000 to 40,000 Da exhibited the best fluidity effect in desert sand mortar.
