Problems solved by technology

The preparation process of red bricks and aerated bricks consumes energy and occupies a large amount in construction waste. If they are directly landfilled, they will occupy a large area and waste resources
In addition, due to the low strength of this part of light construction waste, if it is recycled, it is not suitable to be made into concrete recycled aggregate

Embodiment Construction

[0017] A foamed wall material, using light construction waste as the main raw material, including the following raw materials in parts by weight: 40-60 parts of light construction waste, 15-30 parts of cement, 5-20 parts of admixture, compound Foaming agent 0.5-5 parts, fiber 0.2-0.4 parts, water reducing agent 0.2-0.7 parts, foam stabilizer 0.08-0.15 parts, water 45-65 parts.

[0018] Among them, light construction waste includes: red bricks and aerated bricks, because the strength of red bricks and aerated bricks is low, after the building is demolished, the red bricks and aerated bricks generally only need to be broken slightly to obtain the particle size Particles of ≤31.5mm and particles with a particle size of ≤4.75mm are used as sand, and particles with a particle size between 4.75mm and 31.5mm are used as coarse aggregates to meet the requirements of recycling and reuse by the method of the present invention without further processing Grinding reduces unnecessary proce...

Abstract

The invention discloses a foamed wall material and a preparation method thereof. In the prior art, the method for recycling light construction waste does not exist. A purpose of the invention is to solve the disadvantage in the prior art. The invention provides a foamed wall material, which comprises the following raw materials by weight: 40-60 parts of light construction waste, 15-30 parts of cement, 5-20 parts of an admixture, 0.5-5 parts of a composite foaming agent, 0.2-0.4 part of fiber, 0.2-0.7 part of a water reducing agent, 0.08-0.15 part of a foam stabilizer and 45-65 parts of water.According to the invention, the foamed wall material is prepared by using the light construction waste as the raw material, the characteristics of the light construction waste are fully considered, and the light construction waste does not need to be further grinded after being grinded, so that the procedures and the energy are saved, the high-temperature and high-pressure maintenance with the boiler is not required, the energy consumption is reduced, and the utilization rate of the construction waste is increased.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a foamed wall material and a preparation method thereof. Background technique [0002] With the development of my country's construction industry and the continuous acceleration of urbanization, a large number of buildings have been demolished and rebuilt due to the renovation of old cities and the development of new cities, which has led to a continuous increase in the total amount of construction waste, and most of it has not been rationally utilized, which not only causes environmental damage It puts a lot of pressure on and wastes resources at the same time. At present, the processing methods for construction waste mainly include backfilling mine pits, crushing them to make permeable bricks, or crushing them to make building materials again. [0003] The light waste in construction waste is mainly the mixture of red bricks and aerated bricks. Red bricks are building bricks t...
