Description

Technical Field

[0001] The invention belongs to the technical field of concrete preparation, and in particular relates to a rubber concrete preparation device capable of reducing floating of rubber particles. Background Art

[0002] Rubber concrete (also known as colloid concrete) is a new type of concrete composed of rubber particles (usually from waste tires) and cement. It is a composite material with rubber and cement properties. Rubber concrete is made by using rubber particles as aggregate to partially replace traditional stones or gravel when preparing cement mortar or concrete, and then adding rubber latex and auxiliary admixtures to mix and solidify with cement. As one of the main directions for disposing of waste rubber tires, rubber concrete has considerable potential environmental benefits. In addition, rubber concrete has many advantages over ordinary concrete in terms of mechanical properties and performance, such as light weight, elastic shock absorption, noise reduction and sound insulation, etc. It has broad application prospects in construction engineering, bridge deck and road paving, rail transit and other fields. At the same time, the preparation process and economic efficiency of rubber concrete are not much different from those of ordinary concrete. From a long-term perspective, rubber concrete reuses waste rubber resources, which not only improves resource utilization but also has good economic value.
