Title:
吸着透水性コンクリート
Document Type and Number:
Japanese Patent JP6883455
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a paving concrete having a water permeable property to which a function of fixing carbon dioxide in an atmosphere in an adsorptive manner is applied.SOLUTION: An adsorption permeable concrete comprised of an adsorptive material and a polymeric binder mixed together having a function of adsorbing water, cement, coarse aggregate, carbon dioxide, is characterized in that natural zeolite is used as the adsorption material and is mixed with the coarse aggregate at a volume ratio of 15% to 50%, water permeability coefficient of cured concrete is 1.0×10cm/sec or more. In order to improve tensile strength, it is preferable that high-performance AE water-reducing agent is added at 2% with respect to the mass of the cement.SELECTED DRAWING: Figure 5
