Anti-cracking concrete and preparation method thereof
The invention relates to the technical field of concrete, in particular to anti-cracking concrete and a preparation method thereof. The anti-cracking concrete is prepared from the following raw materials in parts by weight: 200-300 parts of Portland cement, 1000-1400 parts of sand, 60-80 parts of pumice stone, 20-40 parts of organic amine modified bentonite, 30-50 parts of H-series silica powder, 15-25 parts of redispersible latex powder, 6-10 parts of reinforcing fibers, 2-4 parts of aminated graphene, 5-10 parts of a polycarboxylate water reducer, 3-5 parts of a micronized amide wax thixotropic agent and 150-200 parts of water, wherein the reinforcing fibers are selected from one or more of polypropylene fibers, polyacrylonitrile fibers, polyvinyl alcohol fibers and carbon fibers. According to the anti-cracking concrete prepared by the invention, the combinability of the polymer reinforcing fibers and a concrete matrix can be improved without the polymer reinforcing fibers modified, the warping or peeling degree of the surface of the concrete is reduced, and meanwhile, the strength and the cracking resistance of the concrete can also be improved.
本申请涉及混凝土技术领域，具体涉及一种抗开裂混凝土及其制备方法。一种抗开裂混凝土，其原料按重量份包括：硅酸盐水泥200‑300份、砂子1000‑1400份、浮石60‑80份、有机胺改性的膨润土20‑40份、H系硅微粉30‑50份、可再分散乳胶粉15‑25份、增强纤维6‑10份、氨基化石墨烯2‑4份、聚羧酸盐减水剂5‑10份、微粉化酰胺蜡触变剂3‑5份、水150‑200份；所述增强纤维选自聚丙烯纤维、聚丙烯腈纤维、聚乙烯醇纤维、碳纤维中的一种或多种。本申请制备的抗开裂混凝土，可以实现不通过改性聚合物增强纤维来提高聚合物增强纤维与混凝土基体的结合性，降低混凝土表面翘起或剥落程度，同时还能提高混凝土的强度和抗开裂性。
