Title:
A high intensity porous concrete constituent and a high intensity porous concrete hardening object
Document Type and Number:
Japanese Patent JP5975603
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide high strength porous concrete having a coefficient of water permeability of 0.8 cm/sec or more.SOLUTION: The high strength porous concrete composition includes: at least coarse aggregate, fine aggregate, water and a binder, wherein the water to binder ratio is 10-20%, the ratio of unit mortar volume to coarse aggregate particle void volume is 0.35-0.95, and the ratio of unit paste volume to fine aggregate particle void volume is 1.0 or more. The binder is a mixture comprising blast furnace cement, a pozzolan-based fine powder having a BET specific surface area of 15-25 m/g, and an anhydrous gypsum having a Blaine specific surface area of 3,000-12,000 cm/g.
