Effect of Sisal Fibers on the Rheology of Cement Paste Plasticized by Polycarboxylate Superplasticizer
Publisher: ASCE
Abstract: Sisal fibers (SF) and polycarboxylate superplasticizers (PCE) contribute to the sustainable development of cementitious materials by improving and optimizing their hardening properties. In this study, the impact of SF and ...
Optimizing a Polycarboxylate Superplasticizer Molecular Structure to Reduce Apparent Viscosity of Cement Paste at Higher Environmental Temperatures
Publisher: American Society of Civil Engineers
Abstract: A high environmental temperature can increase the apparent viscosity of high-performance concrete mixtures, causing difficulties in mixing, transporting, pumping, and molding the mixtures. Although polycarboxylate ether–based ...
