Interfacial Competitive Adsorption between the Polycarboxylate Superplasticizer and Hydrophobic Emulsion Mitigates Performance Deterioration in Calcium Sulfoaluminate Cement Mortars

Abstract Hydrophobic emulsions (HEs) are widely used to improve the moisture resistance of cement-based materials, but their adsorption on cement particle surfaces can form a physical barrier that retards hydration and compromises mechanical performance. Herein, a polycarboxylate...
