Graphene oxide desert sand cement-based composite material
The invention discloses a graphene oxide desert sand cement-based composite material, and relates to a mixed cement-based composite material, the cement-based composite material is composed of cement, water, sand, a water reducing agent and graphene oxide, the sand is composed of river sand and desert sand, and the weight of the desert sand accounts for 50% of the total weight of the sand; wherein the mass percentage ratio of the cement to the water to the sand to the water reducing agent to the graphene oxide is 1000: 500: 2222.2: (2.5-3.4): 0.1; the cement is P.O42.5 ordinary Portland cement; the water reducing agent is a polycarboxylic acid high-performance water reducing agent. The compressive strength and breaking strength of the desert sand cement-based material can be improved by doping a proper amount of graphene oxide into the desert sand cement-based material, and the mechanical improvement effect of a test block is most obvious after 0-0.01% of graphene oxide is doped into the desert sand cement-based material; the compressive strength and the breaking strength of the graphene oxide full-desert sand test block can be completely similar to those of a standard sand test block; compared with a standard sand test block, the mechanical property of the desert sand test block is obviously improved by doping the graphene oxide.
本发明公开了氧化石墨烯沙漠砂水泥基复合材料，涉及一种混水泥基复合材料，水泥基复合材料由水泥、水、砂、减水剂和氧化石墨烯组成，所述砂为河砂与沙漠砂组成，沙漠砂的重量占砂总量的50％；其中，按质量百分比计，水泥：水：砂：减水剂：氧化石墨烯＝1000：500：2222.2：2.5～3.4：0.1；所述水泥为P.O42.5普通硅酸盐水泥；所述减水剂为聚羧酸高性能减水剂。本发明将适量氧化石墨烯掺入沙漠砂水泥基材料中均能使其抗压、抗折强度提高，由0％～0.01％的氧化石墨烯掺入后试块力学提升效果最为明显；0.03％的氧化石墨烯全沙漠砂试块，抗压、抗折强度完全可以比拟标准砂试块；氧化石墨烯的掺入对沙漠砂试块的力学性能提升相对于标准砂试块更为明显。
