Synthesis and Thermo-Responsive Performance of Chitosan-Based UCST-Type Superplasticizers for Cement Composites

Polysaccharides
Conventional polycarboxylate superplasticizers (PCEs) suffer from uncontrollable adsorption, characterized by rapid initial uptake and limited subsequent release, which causes pronounced slump loss, particularly at elevated temperatures where hydration ...

Property enhancement and mechanism of cement-based composites from the perspective of nano-silica dispersion improvement

Case Studies in Construction Materials
Nano-silica (NS) exhibits significant potential for enhancing the properties of cement materials. However, its effectiveness in improving the properties of cement-based materials is hindered by the poor dispersion of NS within the cement matrix.
