Abstract

The invention discloses high-performance concrete recycled from waste solids and a preparation method thereof. The high-performance concrete recycled from waste solids is prepared by the following steps of: reprocessing waste tires and waste plastics as main recycled materials, removing impurities in the materials, performing corresponding surface treatment, and mixing and stirring the materials with concrete. The high-performance concrete is prepared by replacing a part of aggregate with a rubber particle material, optimizing the proportion to a certain extent and adding a recycled polypropylene fiber material. The freezing resistance, the strength and the durability of the high-performance concrete are improved, and cracks of the concrete are reduced. The durability and anti-crack toughness of the concrete are improved. When cracks are generated and the tips of the cracks extend to the rubber particles, the deformation capability of the rubber particles dissipates the stress at the tips of the cracks, and further extension of the cracks is delayed. By adding the recycled polypropylene fibers, the concrete shows more superior residual strength and fracture energy than common concrete.

Description

technical field [0001] The invention relates to the technical field of concrete preparation, in particular to high-performance concrete for recycling waste solids and a preparation method thereof. Background technique [0002] The amount of waste tires and waste plastics produced in life is huge, and waste tires and waste plastics are generally buried in landfills, but during the process of waste tires and plastics being buried, waste tires pollute the environment, and the landfill location In addition, the utilization rate of waste tires and waste plastics is low, and a small amount of rubber concrete is added with rubber materials during the preparation of concrete, so that the concrete has a certain degree of ductility compared with traditional concrete. However, rubber concrete is not suitable for rubber The utilization rate of waste solids is not very high, and the performance increase of concrete is limited. Therefore, we propose a high-performance concrete and its pre...
