Early age properties and water resistance of calcium hydroxide modified volcanic ash‐based phosphate geopolymer binders

Abstract This work aims to improve the early age characteristics and water resistance of volcanic ash‐based phosphate geopolymer materials by modifying the chemistry of the binder with calcium hydroxide (CH). Phosphate geopolymer binders with Ca/P molar ratios ranging from 0.49 to 0.80 were prepared...
