MANUFACTURING METHOD OF POROUS CONCRETE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing good porous concrete having a uniform structure without causing the occurrence of mortar lumps or the separation of a material even when a body tiltable mixer is used as a mixer for kneading the material of porous concrete. SOLUTION: This manufacturing method of porous concrete includes a process (A) for obtaining a mixture wherein a water reducing agent is uniformly dispersed by mixing 70-100 mass% of coarse aggregate, water and the water reducing agent with respect to the total compounding amount and 0-20 mass% of cement in the body tiltable mixer and a process (B) for obtaining porous concrete by adding the residual amount of the material (mainly cement) to the mixture in the body tiltable mixer to knead the same therewith.
