Title:
POROUS CONCRETE WITH PUMPING FUNCTION
Document Type and Number:
Japanese Patent JP2023161997
Kind Code:
A
Abstract:
To suppress a rise in road surface temperature by vaporization heat caused by evaporation of moisture pumped into a permeable concrete pavement layer having water retention property.SOLUTION: In the porous concrete having a water pumping function obtained by blending water, cement, coarse aggregate, and fine aggregate, the coarse aggregate is No. 7 crushed stone, is mixed as 21 - 29% water-cement ratio in the range of 10 - 30% fine aggregate, and has a water pumping function characterized in that the hydraulic conductivity of the concrete after curing is 1.0×10-2 cm/sec or more and the suction height is 7 cm or more.SELECTED DRAWING: Figure 1
