Abstract

The invention relates to the technical field of preparation of concrete materials, and particularly relates to a heat-insulating and sound-isolating light foamed concrete material and a preparation method thereof. The concrete material comprises the following components in parts by weight: 20-60 parts of cement, 20-40 parts of coal ash, 5-15 parts of sands, 2-15 parts of modified rubber particles, 1-5 parts of foamer and 0.1-5 parts of assistant. Compared with the prior art, the heat-insulating and sound-isolating light foamed concrete material prepared by adopting the technical scheme of the invention is excellent in sound-isolating performance, heat-insulating performance, impervious performance and toughness, can realize the performance indexes of the construction industry standard of PRC: foamed concrete (JG / T266-2011), and is low in production cost and environment-friendly, so that the social benefit can be effectively improved and the social resources are effectively saved. Therefore, the material is suitable for being popularized and applied on a large scale.

Description

technical field [0001] The invention relates to the technical field of concrete material preparation, in particular to a thermal insulation and sound insulation lightweight foamed concrete material and a preparation method thereof. Background technique [0002] With the rapid development of the automobile industry, the types and quantities of waste rubber products will continue to grow. Because waste rubber has good chemical resistance and biological resistance, it is not easy to degrade, and it will pollute the environment after landfill and incineration, and it is difficult to deal with it. How to effectively utilize waste rubber has become a topic of great concern to the research community. Accelerating the comprehensive utilization of waste rubber resources and improving the comprehensive utilization level of waste rubber resources are of great importance for alleviating the shortage of rubber resources in my country and promoting energy conservation and emission reducti...
