▎ 摘 要
NOVELTY - High-fluidity and self-compacting lightweight high-strength concrete, comprises 800-1200 pts. wt. light-burned magnesium oxide, 55-95 pts. wt. floating beads, 310-715 pts. wt. magnesium sulfate heptahydrate, 0-0.5 pts. wt. graphene oxide, 0-2 pts. wt. sodium phosphate, 4-8 pts. wt. citric acid, 250-575 pts. wt. water, and 1-2 pts. wt. antifoaming agent. The citric acid is citric acid monohydrate. The antifoaming agent is polyether modified silicon antifoaming agent. USE - The concrete is useful in concrete pouring interlayer or airtight member (claimed). ADVANTAGE - The concrete can improve the fluidity, initial setting time and concrete strength of the concrete, reduce the density of the concrete, and be applicable to interlayer or airtight components. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing high-fluidity and self-compacting lightweight high-strength concrete.
