MANUFACTURING METHOD OF POROUS CONCRETE

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of porous concrete (POC) capable of manufacturing POC enhanced in uniformity while an agitator vehicle is used. SOLUTION: A cylindrical drum main body arranged in an inclination and having an opening part formed to its upper part and an agitation drum arranged along the inner peripheral surface of the drum main body and having a spiral blade are provided. The agitation drum is constituted so as to kneading coarse aggregate and a binder to manufacture porous concrete using the agitating vehicle constituted so as to perform the forward rotation for downward pushing in an internal housing material by a blade and the reverse rotation for placing the blade to move the same to the opening part. After the coarse aggregate and the binder are housed in the agitation drum, the forward rotation and reverse rotation of the agitation drum are alternately repeated to knead the coarse aggregate and the binder.
