Anti-crack concrete and preparation method thereof
The invention belongs to the technical field of concrete, and particularly relates to anti-crack concrete and a preparation method thereof. The anti-crack concrete provided by the invention is prepared from the following raw materials in parts by weight: cement, fine aggregate, coarse aggregate, mineral powder, fly ash, water, a polycarboxylate superplasticizer and an anti-crack reinforcing agent, the anti-cracking reinforcing agent is prepared by mixing polypropylene fibers and modified acrylic resin; the modified acrylic resin has good impermeability, hydrophobicity and cohesive force, and can significantly improve the crack resistance and impermeability of the polypropylene fiber after being compounded with the polypropylene fiber; the invention also provides a preparation method of the anti-crack concrete. The concrete provided by the invention has excellent compressive strength, breaking strength, crack resistance and impermeability.
本发明属于混凝土技术领域，具体涉及一种抗裂混凝土及其制备方法。本发明提供的抗裂混凝土包括以下重量份数的原料：水泥、细骨料、粗骨料、矿粉、粉煤灰、水、聚羧酸减水剂、抗裂增强剂；所述抗裂增强剂由聚丙烯纤维、改性丙烯酸树脂混合制备而成；所述改性丙烯酸树脂具有良好的抗渗性、疏水性、黏结力，与聚丙烯纤维进行复配，能够显著提高聚丙烯纤维的抗裂性能和抗渗性能；本发明还提供了该抗裂混凝土的制备方法。本发明提供的混凝土具有优异的抗压强度、抗折强度、抗裂性和抗渗性。
