Abstract:new method of producing high-strength porous concrete has recently been developed in Japan. In this method, porous concrete is produced by coating the coarse aggregates with a high-strength mortar, then applying vibration to fuse them. Porous concrete produced bythis method has the following properties. It has a continuous void system with a volumeko-total-void ratio exceeding 85% and a compressive strength of 20 MPa or greater when water permeability is 2 crnkc. The porous concrete produced exhibited good durability in freezing and thawing tests (ASTM C666, Procedure B) and while the amount of drying shrinkage is about 60%, or smaller than that of conventional concrete, such shrinkage occuring very rapidly.
