Anti-cracking high-performance concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses anti-cracking high-performance concrete and a preparation method thereof. The anti-cracking high-performance concrete is prepared from the following components in parts by mass: 90 to 120 parts of cement, 27 to 35 parts of mineral admixture, 240 to 290 parts of fine aggregate, 320 to 390 parts of coarse aggregate, 49 to 59 parts of water, 1 to 3.2 parts of polypropylene fiber, 1.2 to 1.6 parts of water reducing agent and 0.64 to 1.96 parts of anti-cracking aid, the anti-cracking auxiliary agent is at least prepared from the following components: 0.2 to 0.4 part of molybdenum disulfide, 0.08 to 0.14 part of potassium tartrate and 0.36 to 0.42 part of ammonium polyphosphate. The preparation method of the anti-cracking high-performance concrete comprises the step of uniformly mixing the components to obtain the anti-cracking high-performance concrete. The method has the effect of improving the dispersity of the polypropylene fibers in the concrete so as to enhance the anti-cracking performance of the concrete.
本发明涉及混凝土技术领域，具体公开了一种抗开裂高性能混凝土及其制备方法。一种抗开裂高性能混凝土，包括以下质量份数的组分：水泥90~120份、矿物掺合料27~35份、细骨料240~290份、粗骨料320~390份、水49~59份、聚丙烯纤维1~3.2份、减水剂1.2~1.6份、抗裂助剂0.64~1.96份；所述抗裂助剂至少包括以下组分：二硫化钼0.2~0.4份、酒石酸钾0.08~0.14份、聚磷酸铵0.36~0.42份。一种抗开裂高性能混凝土的制备方法在于将各组分混匀，得抗开裂高性能混凝土。本申请具有提高聚丙烯纤维在混凝土中的分散性从而增强混凝土的抗开裂性能的效果。
