Early-Age Properties Development of Recycled Glass Powder Blended Cement Paste: Strengths, Shrinkage, Nanoscale Characteristics, and Environmental Analysis

Recycling solid waste in cement-based materials cannot only ease its load on the natural environment but also reduce carbon emissions of building materials. This study aims to investigate effect recycled glass powder (RGP) early-age mechanical properties and autogenous shrinkage cement pastes, where is replaced by 10%, 20% 30% RGP. In addition, microstructure nano-mechanical paste with different RGP content water binder (W/B) ratio were evaluated using SEM, MIP nanoindentation techniques. The results indicate that decreases increase W/B ratio. While strength deteriorates due addition RGP, it can be compensated reducing Although increases total porosity hardened paste, reduces small size (
