▎ 摘  要

NOVELTY - Waterproof concrete comprises 10-30 wt.% cement, 20-30 wt.% fine aggregate sand, 20-30 wt.% coarse aggregate sand, 10-20 wt.% water and water-proof material, where the water-proof material comprises 0.8-1.2 wt.% graphene and 5-15 wt.% poly vinyl alcohol. USE - Used as waterproof concrete. ADVANTAGE - The concrete preparation method is simple. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the waterproof concrete comprising uniformly stirring fine aggregate sand, coarse aggregate sand and cement, then uniformly mixing the water-proof material with water, pouring the uniformly fine aggregate sand, coarse aggregate sand and cement at natural coagulation state.
