▎ 摘  要

NOVELTY - A gypsum-based foamed concrete comprises 50-65 pts. wt. plaster, 22-28 pts. wt. portland cement, 1-2 pts. wt. sulfoaluminate cement, 1-2 pts. wt. quicklime and/or slaked lime, 13-18 pts. wt. fly ash, 4-8 pts. wt. silica aerogel, 0.2-0.4 pt. wt. graphene oxide, 0.2-0.4 pt. wt. water reducing agent, 0.05-0.1 pt. wt. waterproofing agent and 0.09-0.2 pt. wt. foaming agent. The foaming agent is sodium dodecylbenzene sulfonate and/or sodium lauryl sulfate, and tea saponin compound foaming agent. USE - Gypsum-based foamed concrete. ADVANTAGE - The gypsum-based foam concrete has excellent synergistic effect, water resistance and reduced water absorption rate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the gypsum-based foamed concrete comprising mixing raw materials except foaming agent, adding water, stirring to obtain slurry, adding foaming agent with water to obtain foam, adding slurry, mixing, and molding.
