High-performance rubber concrete

Abstract

The invention relates to high-performance rubber concrete which is prepared by mixing 150-400 parts of concrete, 150-400 parts of rubber particles, 50-60 parts of calcium carbonate, 5-6 parts of crosslinking agent and 2-4 parts of polyvinyl alcohol, and stirring and polymerizing the mixture and polyamic acid resin and a nano-scale modified material at normal temperature, wherein the polyamic acid resin has solid content of 10-25%. The regeneration of waste rubber can be realized, the production process causes no pollution, and the production efficiency is high. The compression resisting strength, the rupture resisting strength and the flexural toughness of the produced concrete are greatly improved.

Description

Technical field: [0001] The invention belongs to building materials, in particular to a high-performance rubber concrete. Background technique: [0002] At present, with the rapid development of the automobile industry, the amount of waste tires is also increasing year by year. Waste tires are industrial hazardous solid wastes, which are one of the harmful wastes that deteriorate the environment, destroy vegetation growth, affect human health, and endanger the ecological environment of the earth. These waste rubber tires are difficult to degrade in the natural environment and can only be disposed of by incineration or landfill. However, when incinerated, many harmful gases such as hydrogen chloride will be produced due to high-temperature combustion, which will cause great harm to the environment. In landfilling, the toxic substances in the rubber will seep out, causing secondary pollution and affecting the use value of the land. Therefore, a new process is needed to obta...
