High-ultimate-tensile hydraulic anti-crack concrete and preparation method thereof
The invention belongs to the technical field of hydraulic concrete, and particularly relates to high-ultimate-tensile hydraulic anti-crack concrete and a preparation method thereof.The high-ultimate-tensile hydraulic anti-crack concrete is prepared from 130-166 kg/m < 3 > of water, 247.6-316.2 kg/m < 3 > of cement, 61.9-79.0 kg/m < 3 > of coal ash, 0.9-5.0 kg/m < 3 > of fiber, 40 kg/m < 3 > of rubber powder, 599-762 kg/m < 3 > of fine aggregate, 1176-1272 kg/m < 3 > of coarse aggregate, 2.2-4.5 kg/m < 3 > of water reducing agent and 0.02-0.03 kg/m < 3 > of air entraining agent according to the weight of each cubic meter of concrete. The anti-cracking concrete has the advantages of high ultimate tensile value, good early-stage anti-cracking performance and the like, the anti-cracking performance of existing concrete is improved, the overall quality of a project is remarkably improved, and the later-stage operation and maintenance cost is reduced.
本发明属于水工混凝土技术领域，具体涉及一种高极限拉伸水工抗裂混凝土及其制备方法，其原材料占比以每方混凝土重量来计，包括以下组分的原材料：水130~166 kg/m3、水泥247.6~316.2 kg/m3、粉煤灰61.9~79.0 kg/m3、纤维0.9~5.0 kg/m3、橡胶粉40 kg/m3、细骨料599~762 kg/m3、粗骨料1176~1272 kg/m3、减水剂2.2~4.5 kg/m3、引气剂0.02~0.03 kg/m3。本发明具有较高极限拉伸值、良好的早期抗裂性能等优点，此发明改善现有混凝土的抗裂性能，显著提高工程整体质量并且降低后期的运行维护费用。
