Enhancing the Reactivity of Dicalcium Silicate Using Aluminum and Sulfur Ions Co‐Doping
Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.ABSTRACT Belite‐rich cements are a lower‐energy and lower‐CO2 alternative to Portland cements, but the low hydraulic activity of belite remains a major limitation. This study explores the impact of aluminum and sulfur co‐doping on the structure and hydration of synthetic dicalcium silicate (C2S).

Innovative Application of SRG for Strengthening Continuous RC Beams
Engineering Reports, Volume 8, Issue 4, April 2026.Steel‐reinforced grout (SRG) effectively strengthens continuous reinforced concrete beams, enhancing flexural capacity by up to 81%. Using geopolymer mortar promotes sustainability while steel fabrics outperform carbon, glass, and PBO alternatives. Low‐density SRG provides superior bonding and structural efficiency, offering a practical solution for ...
