Polypropylene fiber foam light soil based on waste tire rubber powder as well as preparation method and application of polypropylene fiber foam light soil
The invention provides polypropylene fiber foam light soil based on waste tire rubber powder and a preparation method and application of the polypropylene fiber foam light soil, and belongs to the technical field of building material preparation. Research finds that the rubber powder has good shock resistance, it can be considered that the rubber powder is added into the foam light soil to improve the shock resistance and recycle the rubber tires, which is a good solution. In addition, the polypropylene fiber has higher strength and elasticity modulus, is fast to disperse and has strong bond stress with the surface of cement, and when the polypropylene fiber is added into the foam light soil, the breaking strength can be improved, the toughness and crack arrest performance of the light soil can be improved, the fatigue resistance, shock resistance and freeze thawing performance of the light soil can be improved, and concrete cracking can be prevented. The polypropylene fiber can act together with the rubber powder, so that the impact resistance is improved, and the practical application value is good.
本发明提供一种基于废旧轮胎橡胶粉的聚丙烯纤维泡沫轻质土及其制备方法和应用，属于建筑材料制备技术领域。经研究发现，橡胶粉具有较好的抗冲击性能，可考虑将橡胶粉加入到泡沫轻质土中来既能提高抗震性能又能回收利用橡胶轮胎，不失为一种较好的解决方法。此外，聚丙烯纤维具有较高的强度和弹性模量、分散快、与水泥表面握裹力强，其加入到泡沫轻质土中可以提高抗折强度，可以增加轻质土的韧性及止裂性能，还可以提高轻质土的抗疲劳、抗震、冻融性能，阻止混凝土开裂。聚丙烯纤维能和橡胶粉一起作用，提高抗冲击性能，因此具有良好的实际应用之价值。
