NOVELTY - A foam concrete comprises 80-150 pts. wt. cement, 35-60 pts. wt. pulverized coal ash, 0.4-0.6 pt. wt. graphene oxide, 20-40 pts. wt. hydrogen peroxide, 1-2 pts. wt. coconut oil fatty acid diethanolamide, 0.5-0.8 pt. wt. lithium carbonate, 1.5-3.0 pts. wt. polypropylene fiber and 130-240 pts. wt. water. USE - Foam concrete used for construction material field. ADVANTAGE - The foam concrete solves the problems about poor stability, non-uniformity and low compressive strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the foam concrete comprising weighing raw materials, adding graphene oxide to a portion of water, ultrasonically dispersing to obtain graphene oxide aqueous solution, adding coconut oil fatty acid diethanolamide, stirring at room temperature, hydrothermally reacting, cooling to room temperature, adding hydrogen peroxide, stirring, heating, foaming, adding polypropylene fiber and lithium carbonate, uniformly mixing, adding remaining portion of water while stirring, mixing cement and pulverized coal ash, adding to mixed material, uniformly mixing to obtain cement slurry foam mixture, placing in mold, shaking for 1-2 minutes, smoothening, curing for 1-2 days, stripping and curing for 26-28 days.
