Anti-crack concrete and preparation method thereof
The invention relates to the technical field of concrete, and provides anti-crack concrete and a preparation method thereof, the anti-crack concrete comprises cement, aggregate, a polycarboxylic acid water reducer, a wear-resistant agent, basalt fiber, water, fly ash, calcium sulphoaluminate, light calcined magnesium oxide, calcined magnesium oxide, hydroxy propyl cellulose ether, urea, super absorbent resin, polypropylene fiber and ferric trichloride. The aggregate comprises coarse aggregate and fine aggregate; the mass part ratio of the coarse aggregate to the fine aggregate is 1: 1; and the polycarboxylic acid water reducing agent is a PCA-I type polycarboxylic acid water reducing agent. The concrete provided by the invention is good in crack resistance, the invention further provides a concrete preparation device aiming at the method, the concrete preparation device is used for producing the crack-resistant concrete, resource waste is avoided, the production cost is saved, and the crack resistance of the concrete is improved.
本发明涉及混凝土技术领域，本发明提供了一种抗裂混凝土及其制备方法,抗裂混凝土包括：水泥、骨料、聚羧酸减水剂、耐磨剂、玄武岩纤维、水、粉煤灰、硫铝酸钙、轻烧氧化镁、煅烧氧化镁、羟丙基纤维素醚、尿素、高吸水树脂、聚丙烯纤维和三氯化铁。所述骨料包括：粗骨料和细骨料；所述粗骨料与细骨料的质量份数比例为1:1；所述聚羧酸减水剂为PCA‑I型聚羧酸减水剂。本发明的混凝土抗裂性能好，本发明针对方法还提供了混凝土制备装置，用于生产抗裂混凝土，避免浪费资源，节省生产成本，提高混凝土抗裂能力。
