Abstract

To provide a novel hydraulic composition which is manufactured using a general-purpose raw material and has reduced carbon dioxide (CO2) generation during production.SOLUTION: A manufacturing method of a hydraulic composition includes: obtaining a cementitious hardened material; obtaining a carbonated cementitious hardened material containing a pozzolanic ingredient by fixing carbon dioxide to the cementitious hardened material and conducting carbonation treatment on it; and obtaining a hydraulic composition containing a pozzolanic ingredient and an alkaline ingredient by mixing the cementitious hardened material and the carbonated cementitious hardened material.SELECTED DRAWING: None
