PRODUCTION OF HYDRATED HARDENED BODY

摘要

PURPOSE:To provide a method for producing hydrated hardened body capable of obtaining the useful hydrated hardened body by using various industrial wastes containing SiO2. CONSTITUTION:The hydrated hardened body is obtained by adding a calcium based hydraulic agent forming a hydraulic component by the reaction with SiO2 component into a siliceous raw material composed mainly of SiO2 so as to be 0.06-1.0 in the mol ratio of Ca/Si and allowing the mixture to react with water in a autoclave at 180-220 deg.C under saturated steam pressure for 2-10 hours.
