Problems solved by technology

But it still has certain defects, such as long preparation time and high cost, and the mechanical properties of foam concrete are not as good as ordinary concrete.
At the same time, there are many waste materials piled up in rural areas or cities, which not only take up space, but also pollute the environment

Abstract

The invention discloses a method for using a waste material to prepare a heat insulating wall. The heat insulating wall is formed by foam concrete, the waste material and an additive, and the waste material comprises one of crushed wood chip, broken glass, straw and waste gypsum; and according to the quality part, the raw material of the foam concrete comprises: 23-33 parts of cement, 15-25 parts of sand, 1-5 parts of cement foaming agent, 30-40 parts of lime, 10-20 parts of perlite, and 50-65 parts of water. The method comprises the steps: during the preparation, weighing the cement, sand, lime, perlite and water according to the weight part, uniformly mixing and stirring, adding the waste material and additive, uniformly stirring, and obtaining slurry; adding the water to the cement foaming agent for foaming; uniformly stirring the foam and slurry, forming a wallboard, and installing glass fiber gridding cloth in the wallboard; and obtaining the heat insulating wall by the maintenance. The method is capable of improving the utilization ratio of the waste material, and has the characters of simple preparation working procedure, short elapsed time, light heat insulating wall, heat preservation, heat insulation, low cost, safety, fastness, and difficult cracking.

Description

technical field [0001] The invention relates to a method for preparing building materials, in particular to a method for preparing a thermal insulation wall using waste materials. Background technique [0002] With the development of society, the country implements the wall reform policy to achieve the purpose of protecting land and saving energy. In recent years, more and more types of new wall materials have appeared in the society, among which there are more applications, such as gypsum or cement lightweight partition boards, color steel plates, aerated concrete blocks, steel wire grid foam boards, small Concrete hollow blocks, gypsum boards, gypsum blocks, ceramsite blocks, sintered porous bricks, shale bricks, solid concrete bricks, PC slabs, horizontal hole concrete wall panels, activated carbon walls, new partition wall panels, etc. New wall materials are new types of wall materials that are different from traditional wall materials such as bricks and tiles, limeston...
