▎ 摘　　要

NOVELTY - The graphene oxide desert sand cement-based composite material, comprises cement, water, sand, a water reducing agent and graphene oxide in a mass ratio of 1000: 500:2222.2: 2.5-3.4: 0.1, respectively. The sand consists of river sand and desert sand. The amount of the desert sand is 50 wt.%. The cement is P.O42.5 ordinary Portland cement. The water-reducing agent is a polycarboxylate high-performance water-reducing agent. USE - Graphene oxide desert sand cement-based composite material. ADVANTAGE - A proper amount of graphene oxide is doped into a desert sand cement-based material, so that the compressive strength and the flexural strength of the desert sand cement-based material are improved. The mechanical improvement effect of the test block is most obvious after 0-0.01% of graphene oxide is doped. The mechanical property improvement of the graphene oxide to the desert sand test block is more obvious compared with that of a standard sand test block. Through microscopic mechanism analysis, the mutual promotion effect of the desert sand and graphene oxide and the graphene oxide action mechanism are reasonably explained, and a basis is provided for further research. The composite materials have positive economic and practical significance in the aspects of environmental protection, desertification inhibition, local material utilization and reasonable utilization. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the graphene oxide desert sand cement-based composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a graph showing the relationship between compressive strength and desert sand doping amount after a test piece 7 days.
