Investigation of the Behavior and Mechanism of Action of Ether-Based Polycarboxylate Superplasticizers Adsorption on Large Bibulous Stone Powder

Abstract: The aim of this paper is to study the adsorption behavior of polycarboxylate superplasticizers (PCE) on coarse aggregates with a property of high water consumption (above 2%). The coarse aggregates were ground into a powder to create large bibulous stone powder, and it was observed that significant amounts of the ether-based PCE were absorbed onto large bibulous stone powder. The adsorption rate immediately reached a maximum after 5 min and then gradually decreased until an equilibrium absorption was establish… Show more

“…On the other hand, dispersion by steric hindrance has been found to manifest in carboxylate SP [46]. Research reveals that the zeta potential responsible for dispersion in the case of these SP is much lower [44] and that the cement particle almost appear neutral [45].…”
