Problems solved by technology

[0003] Because the density of rubber particles is quite different from that of sand and cement, and the bonding between rubber particles and cement is relatively weak, most of the rubber concrete made by traditional methods has layers and uneven distribution of rubber, which greatly reduces the The mechanical properties of rubber concrete, and its degree of delamination is difficult to control, making rubber concrete samples or components have large individual differences

Abstract

The invention provides a novel rubber concrete material. The novel rubber concrete material comprises the following raw materials: cement, sand, rubber particles, a water reducing agent, hydroxypropyl methyl cellulose and water. The invention also discloses a preparation method of the novel rubber concrete, which comprises the following steps: screening rubber particles and sand with proper particle sizes, measuring cement, sand, rubber, a water reducing agent and water with required weight, pouring the cement, sand and rubber into a container, carrying out dry mixing to obtain a uniform rubber-sand-cement mixture, fusing the water reducing agent, hydroxypropyl methyl cellulose and water, slowly pouring water containing the water reducing agent and the hydroxypropyl methyl cellulose into the container filled with the rubber, the sand and the cement, and conducting stirring while adding the water until the materials are uniformly stirred; and loading the uniformly stirred slurry into a mold within 15 minutes, uniformly conducting vibrating, conducting standing for 3-4 hours, removing the mold, and conducting curing to obtain the required rubber concrete. The rubber concrete disclosed by the invention has good energy absorption and vibration reduction performance.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a novel rubber concrete material, and also to a preparation method of the novel rubber concrete. Background technique [0002] In recent years, the problem of environmental pollution caused by discarded tires has become more and more serious, making the research on its recycling become a hot topic, and has achieved rich research results. Based on this, a new type of rubber concrete anti-seismic material is proposed, which can not only solve the problem of waste rubber by reusing waste. Pollution problems can also change the mechanical properties of concrete and improve the earthquake resistance of concrete. [0003] Because the density of rubber particles is quite different from that of sand and cement, and the bonding between rubber particles and cement is relatively weak, most of the rubber concrete made by traditional methods has layers and uneven distribution of rubb...
