▎ 摘　　要

NOVELTY - High-strength cement-based composite material comprises 23-48 pts. wt. gelling material, 18-35 pts. wt. aggregate, 0.3-1.2 pts. wt. calcium carbonate crystal whisker, 1-8 pts. wt. acrylic emulsion, 0.4-1.8 pts. wt. polyvinyl alcohol fiber, 0.3-1 pts. wt. water reducing agent, 0.2-1 pts. wt. antifoaming agent, and 12-36 pts. wt. water. The gelled material comprises 8-28% limestone powder, 1-4% calcium sulfate, 3-16% fly ash, 5-25% reinforcing auxiliary material, and silicate cement (remaining amount). The reinforcing auxiliary material is porous coal gangue powder loaded with carboxylated graphene oxide. USE - The composite material is useful to airport pavement. ADVANTAGE - The material has excellent flexural, compressive and impact resistance properties, high mechanical strength can meet the application requirements of the airport pavement, bending resistance, impermeability and impact resistance of cement. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the high-strength cement-based composite material.
