Recycled concrete as well as preparation method and application thereof
The invention belongs to the technical field of recycled concrete, and particularly relates to recycled concrete as well as a preparation method and application thereof. Waste concrete blocks are crushed and recycled to serve as coarse and fine aggregates of the recycled concrete, meanwhile, retired automobile bumper plastic parts are crushed and recycled to obtain polypropylene particles, the polypropylene particles are used for filling gaps of the recycled concrete aggregates, the void ratio of the recycled concrete is reduced, the mechanical property of the recycled concrete is improved, and the polypropylene particles have high ductility and are not prone to deformation. The polypropylene particles are added, the workability of the recycled concrete can be improved, shrinkage cracking of the recycled concrete is inhibited, and meanwhile the corrosion resistance of the recycled concrete is improved by means of the corrosion-resistant material performance of the polypropylene particles. The waste concrete blocks and the decommissioned automobile bumper plastic parts are used as raw material sources of the recycled concrete, the utilization rate of the waste concrete and the decommissioned automobile waste plastic parts can be increased, the economic value and resource recycling of the recycled concrete are achieved, and environmental pollution is reduced.
本发明属于再生混凝土技术领域，具体涉及一种再生混凝土及其制备方法和应用。本发明通过破碎回收废弃混凝土块，作为再生混凝土的粗、细骨料，同时通过破碎回收退役汽车保险杠塑料件得到聚丙烯颗粒，将其用于填充再生混凝土骨料的空隙，减少再生混凝土的空隙率，提升其力学性能，而且聚丙烯颗粒具有高延展性，能增加再生混凝土的和易性，抑制再生混凝土的收缩开裂，同时利用聚丙烯颗粒自身抗腐蚀的材料性能，提升再生混凝土耐腐蚀性能。本发明利用废弃混凝土块和退役汽车保险杠塑料件作为再生混凝土的原料来源，能提高废弃混凝土、退役汽车废弃塑料件的利用率，实现再生混凝土的经济价值和资源循环利用，减少环境污染。
