▎ 摘 要
NOVELTY - Super-fluid-free and high performance concrete comprises 20-35 pts. wt. cement, 10-25 pts. wt. slag, 3-5 pts. wt. ash, 2-8 pts. wt. silica fume, 1-3 pts. wt. oxide graphene dispersion liquid and 40-60 pts. wt. river sand, where the concrete further comprises a composite additive and steel fiber, and the doping amount of composite additive is 0.35-0.6wt% of the sum of cement, slag, fly ash and silica fume, and the content of the steel fiber is 1-3 vol.% of total concrete volume. USE - Used as a super-fluid steam-free and ultra-high performance concrete. ADVANTAGE - The concrete utilizes blast furnace slag with fast hydration at normal temperature, thus expansibility meets the field construction requirement and ensures good construction performance, and improved hydration degree of cement, bridging micro-crack, and improved whole performance of the base body. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the super-fluid steam-free and ultra-high performance concrete.
