Problems solved by technology

[0003] Due to the accelerated pace of urbanization across the country, a large amount of waste concrete has been produced. How to solve the stacking of waste concrete and make full use of these waste concrete has become an urgent problem to be solved. The traditional treatment method is mainly landfill, which not only takes up a lot of waste. fill the site, but also cause environmental pollution

Abstract

The invention discloses a recycled concrete polyphenyl particle light thermal insulation hollow building brick and a preparation method thereof. The recycled concrete polyphenyl particle light thermal insulation hollow building brick comprises the following raw material components in parts by weight: 420 kg of cement, 185 kg of water, 1,152 kg of recycled coarse aggregate, 622 kg of fine aggregate and 0.35 m<3> of polyphenyl particles. The preparation method comprises the following steps of: (1) firstly, placing and uniformly stirring the fine aggregate, the cement and the polyphenyl particles; (2) stirring while adding the water to fully contact cement slurry with the polyphenyl particles, fully adhering boundaries of two phases, and fully wrapping the particles with the cement slurry; and (3) finally adding the recycled coarse aggregate, stirring while adding water to uniformly distribute various raw materials, and controlling concrete vibrating time to be 10-15 seconds. By using the recycled concrete polyphenyl particle light thermal insulation hollow building brick and the preparation method thereof, the waste concrete and the polyphenyl particle garbage can be fully utilized, the strength of the building block meets the requirements of the non-load-bearing walls, and the building block has the advantages of light weight, thermal insulation, heat insulation, environmental friendliness and the like.

Description

1. Technical Field [0001] The invention relates to a non-load-bearing wall material in construction engineering in the field of civil engineering and a preparation method thereof, in particular to a lightweight heat-insulating hollow block of recycled concrete polystyrene particles and a preparation method thereof. 2. Background technology [0002] Wall material is a kind of building material that is used very large in the field of construction engineering. With the rapid development of urban and rural construction in my country, the demand for wall materials has increased sharply. The traditional wall materials are mainly clay bricks and non-energy-saving Building materials are mainly used, which not only destroys arable land and wastes resources, but also causes environmental pollution. Therefore, the promotion of wall material innovation is a concrete manifestation of the development of a circular economy and the construction of a resource-saving society. It is of great signifi...
