Abstract

The invention belongs to the technical field of new materials and discloses elastic concrete. The elastic concrete comprises the following raw materials in parts by weight: 30-40 parts of cement, 10-20 parts of slag powder, 40-80 parts of rubber particles, 1-3 parts of a composite fiber, 0.01-0.05 part of polyoxyethylene sorbitan monostearate, 30-60 parts of emulsified asphalt, 10-30 parts of water-borne epoxy resin, 0.5-2 parts of a polycarboxylate superplasticizer, 0.01-0.05 part of a defoamer, 1-2 parts of calcium metaaluminate, 3-8 parts of modified zeolite powder, 50-60 parts of sand and10-30 parts of water. The elastic concrete is compounded by inorganic materials, is low in price, high in elasticity, good in flexibility and excellent in anti-freezing property, can be used for outdoor works, can effectively absorb an impact force brought by exercise, improves the degree of comfort during exercise and reduces injuries of the impact force on a body; and as the rubber particles arelow in heat conductivity coefficient and high in flexibility, an outdoor sport field can be prevented from free-thaw damages, and the service life of the field is prolonged.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to elastic concrete. [0002] technical background [0003] With the development of urban construction and the improvement of people's living standards, people expect the ground of leisure, fitness and entertainment venues such as sports fields and exhibition halls to have a certain degree of elasticity and noise reduction. At present, some sports grounds are laid with plastic track, and the main component is polyurethane material, which is expensive. [0004] At the same time, with the rapid development of the automobile industry, the generation and accumulation of a large number of waste rubber tires has constituted a serious "black pollution". Processing waste rubber materials and mixing them into concrete can not only solve the problem of environmental pollution caused by waste rubber, but also make good use of the elasticity of rubber powder to prepare concret...
