NORMAL CONCRETE FOR PREVENTING CRACK TO SECURE OPTIMUM AIR CONTENT BY MIXING REFINED OIL FOR REFORMING EMULSIFICATION

摘要

Disclosed is a normal concrete for preventing cracks to secure the optimal air content by mixing refined oil for reforming emulsification. The normal concrete for preventing cracks to secure the optimal air content by mixing refined oil for reforming emulsification comprises refined oil for reforming emulsification to mixing of an admixture to prevent a reduction in the air amount occurring in normal concrete with the compression strength of 50 MPa or less. Accordingly, by refining or using waste edible oil, the normal concrete of the present invention is environment-friendly, can secure the optimal air content which is a characteristic of normal concrete unlike high strength concrete, and can minimize changes in quality of deposited concrete by preventing drying shrinkage cracking during curing.;COPYRIGHT KIPO 2019
