Title:
How to make cast-in-place porous concrete
Document Type and Number:
Japanese Patent JP6347514
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing cast-in-place porous concrete, in which the water permeability, executability and durability of the cast-in-place porous concrete are made excellent by managing specific fresh properties of the porous concrete.SOLUTION: The method for producing cast-in-place porous concrete comprises a step of managing the fresh properties of the cast-in-place porous concrete, which contains Portland cement, an inorganic admixture, fine aggregate, coarse aggregate, water and a high-performance AE water reducing agent, so that a void ratio becomes 20-25 volume%, porosity without vibration becomes 36 volume% or lower and a mortar flow-down ratio becomes 50 volume% or lower.SELECTED DRAWING: None
