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.
