Thermal insulation and sound insulation concrete and preparation method thereof

Abstract

The invention belongs to the technical field of concrete, and discloses thermal insulation and sound insulation concrete and a preparation method thereof, the thermal insulation and sound insulation concrete comprises the following raw materials by mass: 80-120 parts of cement, 10-30 parts of rubber powder, 70-90 parts of rock wool slag and 20-40 parts of polyurethane particles. The prepared thermal insulation and sound insulation concrete has excellent thermal insulation effects and good thermal insulation and sound insulation effects.

Description

technical field [0001] The invention belongs to the technical field of concrete, and in particular relates to a heat-preserving and sound-insulating concrete and a preparation method thereof. Background technique [0002] Beijing and other cities have restricted the use of clay ceramsite and shale ceramsite, and there is actually no supply of ceramsite. After research, experimentation, and development of a dry-mixed composite light aggregate concrete cushion (referred to as "composite light aggregate cushion") to replace ceramsite concrete, this dry mix can be constructed by adding water and stirring on site. [0003] At present, the application process of dry-mixed composite light aggregate is energy-saving and environmentally friendly, the construction process is simple, the quality is easy to control, and the material has good durability and crack resistance. It is a good cement product and can completely replace the ceramsite concrete cushion construction. , the above c...

Problems solved by technology

[0003] At present, the application process of dry-mixed composite light aggregate is energy-saving and environmentally friendly, the construction process is simple, the quality is easy to control, and the material has good durability and crack resistance. It is a good cement product and can completely replace the ceramsite concrete cushion construction. , the above cement products generally have the characteristics of high thermal conductivity and poor thermal insulation performance, which cannot meet the national requirements for building energy conservation. Using the above materials requires a thermal insulation layer on the outer or inner surface of the wall to meet the relevant specifications. requirements, and there are still defects such as poor thermal insulation effect and heavy weight
