Enhanced Workability and Hydration Control of α-Calcium Sulfate Hemihydrate via Sodium Hypophosphite–Modified PCE

Abstract

AbstractThis study investigates the performance of a phosphate-modified polycarboxylate superplasticizer (P-PCE) synthesized using sodium hypophosphite as the phosphorus source in α-calcium sulfate hemihydrate (α-HH) systems. The effects of conventional ...Practical ApplicationsGypsum-based materials, such as self-leveling compounds and high-strength plaster, are valued for their environmental benefits. However, their rapid hardening often complicates handling and application at construction sites. This ...
