HIGH STRENGTH CONCRETE BODY HAVING BOTH WATER PERMEABILITY AND WATER RETENTIVITY

摘要

PPROBLEM TO BE SOLVED: To provide a concrete body having excellent water permeability and water retentivity and reinforced in mechanical strength such as crack resistance. PSOLUTION: Porous aggregate such as water granulated slag, zeolite and volcanic rock, a water-absorbing resin such as a water-soluble polymer, a vitreous, metallic or high polymer fibrous material and a hardening material such as portland cement, ecocement, high strength cement or high-early-strength cement are kneaded to be hard with each other in a zero or low slump state, formed and placed.
