▎ 摘　　要

NOVELTY - The method comprises (i) using 53-58 pts. wt. water, 90-100 pts. silicate cement, 20-30 pts. fly ash with different grain diameters, 6-8 pts. silicon ash, 0.05-0.1 pts. foaming agent, 0.5-1 pts. water reducing agent, 0.08-0.15 pts. thickening agent, and 0.1-0.15 pts. graphene oxide modified carbon fiber, stirring into concrete slurry, and mixing silicate cement, fly ash, silica ash, and graphene oxide modified carbon fibers with different particle sizes into concrete slurry with water, (ii) diluting the foaming agent with water into foaming agent solution, (iii) making the foaming agent solution into foam by a compressed air foaming machine, (iv) mixing the foam into the concrete slurry, adding water reducing agent and thickening agent and mixing and stirring the concrete slurry mixed with foam to obtain foamed concrete mixture, and (v) using the foamed concrete mixture for construction forming and maintaining to obtain the high performance lightweight foam concrete. USE - Method for preparing high performance light foam concrete, which is useful for building materials. ADVANTAGE - The concrete has a more uniform and dense pore structure with industrial value, and improved compressive strength, and the anti-cracking performance, and can inhibit the early shrinkage.
