Polycarboxylate Superplasticizer

In this paper, the adsorption behavior of polycarboxylate superplasticizer (PC) on cement was examined. Through adsorption of PC, adsorption area of the molecule was calculated, and it is found that PC molecule would maintain curled shape when it was adsorbed on the surface of cement particles.

Performance And Mechanism

A type of slow-release polycarboxylate superplasticizer (PCE) was prepared and its application performance and mechanism were studied systematically. The experimental results of cement and concrete showed that the prepared slow-release PCE can slowly play a dispersing role and finally achieve a good dispersing effect within 120 minutes. Its adsorption behavior on the surfaces of cement particles was measured by a total organic carbon (TOC) analyzer, displaying the validity of slow adsorption. The hydrate exothermic curves showed that the slow-release PCE only delayed the hydration but did not affect the hydration heat and workability of concrete.
