Abstract
Based on the chemistry of alinite compound, we have successfully converted a wide variety of flyashes and other mineral, industrial and municipal waste materials into a new class of hydraulic setting alinite cements. Three case studies are presented for producing good quality alinite cements from representative samples of flyash from a thermal power plant in India, tailings sands from an Indian gold processing plant and chloride rich municipal incinerator ash obtained from South Korea. The process parameters optimized include raw mix composition—represented by lime index and chloride content—clinkering temperature schedule and clinker grinding fineness.
