METHOD FOR PRODUCING CONCRETE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a concrete composition in which a concrete hardened body with sufficient strength can be obtained even when waste materials are used.

SOLUTION: The method for producing a concrete composition includes: adding water and a water reducing agent to a mixture containing a material with pozzolanic reactivity comprising a granular material or the like obtained by comminuting clay roof tile scrap, brick scrap or pottery scrap, and an active material comprising lime or the like which activates the material with pozzolanic reactivity; activating the material with pozzolanic reactivity; and kneading the resulting activated mixed liquid with cement and aggregate to generate the objective concrete composition.
