Carbonation in Industrial by-Products Based Blended Mortars: A Vital Durability Hypothesis

This book comprises an experimental study that investigates the carbonation resistance of blended mortars incorporating various industrial by-products such as coal bottom ash, iron slag, copper slag, and silica fume. Carbonation, a chemical reaction between atmospheric CO₂ and cement hydration products, reduces the alkalinity of concrete, impacting durability. Blended mortars-formed by partially replacing cement or sand with pozzolanic and cementitious wastes-were subjected to accelerated carbonation tests over different exposure periods. The experimental findings identify the optimal types and proportions of by-products that enhance carbonation resistance, with supplementary insights into the fundamental strength performance of blended mortars. The outcomes support the effective utilization of industrial wastes in improving the durability of cement-based materials.
