Embodiment 1

[0030] An environment-friendly, sound-insulating and waterproof concrete wall brick, the preparation method of which comprises the following steps:

[0031] 1) The construction waste is crushed, sorted, screened, shaped, cleaned, and dried to obtain recycled coarse and fine aggregates, wherein the particle size of the recycled coarse aggregate is 5-30mm, and the particle size of the recycled fine aggregate is 0-5mm;

[0032] 2) Mix 60 parts of cement, 35 parts of recycled coarse aggregate, 10 parts of ceramsite, 20 parts of recycled fine aggregate, 5 parts of bamboo fiber, 2 parts of silica sol, 0.5 parts of water reducing agent, and 20 parts of water, and mix well ,spare;

[0033] Among them, bamboo fiber is obtained by bleaching with hydrogen peroxide and drying naturally, with a tensile strength greater than 120MPa, a length of 10-20mm, an equivalent diameter of 2-3mm, and a water content of 8%-10%; ceramsite is made by adding cement to waste cinders. The non-burning garba...

Abstract

The invention relates to an environmental-friendly soundproof waterproof concrete wall brick and a preparation method thereof, and belongs to the technical field of a building material. The method comprises: firstly, carrying out processing of crushing, sorting and the like on building waste to obtain recycled coarse and fine aggregate; then carrying out batching on cement, the recycled coarse aggregate, haycite, the recycled fine aggregate, bamboo fibers, silica sol, a water reducing agent and water, and uniformly stirring; after sufficiently foaming a foaming agent by a foaming machine, mixing foam and slurry to prepare foam concrete; then carrying out pumping, injection molding and maintenance and demoulding to take the brick; finally, coating the surface with a modified polyurethane waterproof paint. The method is simple to operate; used raw materials are nonhazardous; the problem of the building waste can be effectively solved; the obtained concrete wall brick has the advantages of high intensity, good soundproof effect, excellent waterproof performance and the like.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an environment-friendly, sound-insulating and waterproof concrete wall brick and a preparation method thereof. Background technique [0002] With the continuous acceleration of the urbanization process, the amount of construction waste generated and discharged in the city is also increasing rapidly. While enjoying urban civilization, people are also suffering from the troubles caused by urban garbage. Among them, construction waste accounts for a considerable proportion, accounting for 30% to 40% of the total garbage. This undoubtedly aggravates the relationship between people and the environment. Therefore, how to deal with and utilize construction waste has become an important issue faced by government departments at all levels and construction waste disposal units. [0003] Many wastes in construction waste can be reused as renewable resources after sor...
