NOVELTY - Special admixture comprises 10-15 pts. wt. composite aluminum powder, 12-15 pts. wt. re-dispersible latex powder, 10-15 pts. wt. dispersant, and 20-30 pts. wt. air-entraining agent. The preparation of composite aluminum powder comprises dispersing nano-aluminum powder in ethanol solution for 2-5 minutes in a vacuum environment, adding organic phosphorus compound and dispersing ultrasonically for 2-5 minutes, adding epoxy resin and/or epoxy thinner and continuing to disperse for 2-5 minutes, suction filtering, and drying at 90-100°C to obtain first treatment powder; where the ratio of nano-aluminum powder, ethanol solution, organic phosphorus compound, epoxy resin/epoxy thinner is 0.1-0.2:1-10:0.01-0.02: 0.01-0.02. USE - The special additive is useful for aerated concrete containing fluorite ore, which is used as a core for research. No biological data given. ADVANTAGE - The special additive can reduce the aerated concrete water absorption, so as to improve the whole performance of the Aerated concrete. The air entraining agent in the additive formulation is good for reducing the slump of the aerate concrete doped with fluorite ore, and reducing the brittle after the aerating concrete is formed. The additive reduces the aggregate graphene aggregate/aluminum composite powder has more uniform micro-structure, and the hydration reaction has better stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for air entraining agent.
