▎ 摘　　要

NOVELTY - High-strength high anti-seepage layer graphene concrete comprises 360-390 pts. wt. cement , 1000-1250 pts. wt. stone , 630-660 pts. wt. medium sand , 0.01-0.35 pts. wt. less-layer graphene and 200-240 pts. wt. water. USE - Used as high strength and high anti-seepage layer graphene concrete. ADVANTAGE - The concrete has bridging effect in high-strength and high anti-seepage layer graphene concrete, is good for filling high-strength high anti-seepage small-layer graphene concrete inner hole, connecting micro-crack, improving concrete impermeability, graphene has template effect due to larger specific surface area, promoting the formation of hydration product, making the concrete more compact, so as to improve the micro structure in the concrete, and improving the mechanical property, compared with graphene oxide, a few layers of graphene does not need modified oxidation, and the cost is low. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation method of high-strength and high anti-seepage layer graphene concrete.
