Anti-crack concrete containing modified polypropylene fiber and preparation method thereof
The invention discloses anti-crack concrete containing modified polypropylene fiber and a preparation method, the anti-crack concrete is prepared from the following main components: a strength improving component, a crack resistance improving component and a reinforcing component, and the strength improving component is composed of cement, a gelling agent, machine-made sand, broken stone and a water reducing agent. The strength of the concrete can be enhanced through the cement, the gelling agent, the machine-made sand, the gravel and the water reducing agent, the phenomenon of insufficient strength is avoided, the crack resistance of the concrete can be enhanced through the aggregate, the fly ash, the mineral powder, the additive and the modified polypropylene fiber, the phenomenon of cracking during use is avoided, and the service life of the concrete is prolonged. Through the clay, lime, gypsum and volcanic ash, the overall mixability of the concrete can be better, the phenomenon of dispersion is prevented, and the problems that the overall service life cannot be guaranteed and the use quality of the concrete is affected due to the fact that the surface of the concrete is prone to cracking after long-time use are solved.
本发明公开了一种含有改性聚丙烯纤维的抗裂混凝土及制备方法，所述抗裂混凝土制备配方的主要成分为：提高强度成分、提高抗裂性成分和加固成分，所述提高强度成分由水泥、凝胶剂、机制砂、碎石和减水剂组成。本发明通过水泥、凝胶剂、机制砂、碎石和减水剂，能够对混凝土的强度进行加强，避免出现强度不够的现象，通过骨料、粉煤灰、矿粉、外加剂和改性聚丙烯纤维，能够对混凝土的抗裂性进行加强，避免出现使用时开裂的现象，通过粘土、石灰、石膏和火山灰，能够使混凝土整体的糅合性更好，防止出现分散的现象，解决了在长时间使用时其表面容易开裂，这就导致整体的使用寿命得不到保障，影响了混凝土的使用质量。
