Problems solved by technology

At present, there are two main ways to deal with waste clay bricks: one is to transport them to the suburbs for burial, occupying and embezzling a large amount of agricultural land; the other is to transport them to rivers and dump them to affect flood discharge during the flood season, and at the same time deteriorate and pollute the natural and ecological environment
In addition, the iron ore slag discharged by iron and steel enterprises is also difficult to deal with

Embodiment Construction

[0018] The preparation steps of the present invention include:

[0019] (1) Ingredients

[0020] Use a dry ball mill to mix and grind the waste clay bricks and iron ore slag, and control the particle size to 60-150 mesh. Then sequentially add CaCl 2 , water, calcium carbonate, glass fiber for mixing. The length of the glass fiber is 1-2cm, and the glass fiber is used to improve the overall bending strength of the lightweight wallboard.

[0021] The ratio is as follows: the amount of waste clay bricks is 38.5 parts, the amount of iron ore slag is 21 parts, CaCl 2 The consumption is 1 part, the calcium carbonate consumption is 1.5 parts, the glass fiber consumption is 2 parts, and the water consumption is 36 parts.

[0022] The chemical composition of waste clay bricks and iron ore slag is shown in Table 1, and its main composition is found from the table to be SiO 2 、Al 2 o 3 , CaO, the active substances are mainly CaO and Al 2 o 3 .

[0023] Table 1 Chemical composit...

Abstract

The invention discloses a light wallboard and a preparation method. The light wallboard is characterized in that waste clay bricks and iron ore slag are used as main materials, CaCl2 is used as a compound activator, and calcium carbonate is used as a dispersant; and glass fibers are also doped, wherein the length of the glass fibers is 8-15mm. The light wallboard comprises the following materialsin parts by weight: 37-40 parts of waste clay brick, 20-22 parts of iron ore slag, 1-2 parts of CaCl2, 1-2 parts of calcium carbonate, 1-3 parts of glass fiber and 34-38 parts of water. The light wallboard has the characteristics of low density, high strength and low cost.

Description

technical field [0001] The invention relates to the field of construction, in particular to a lightweight wallboard and a preparation method. Background technique [0002] With the development of urban construction, waste will be generated during the maintenance and demolition of buildings, and discarded clay bricks are one of them. There are two main ways to deal with waste clay bricks: one is to transport them to the outskirts for burial, occupying and embezzling a large amount of agricultural land; the other is to transport them to rivers and dump them to affect flood discharge during flood seasons, and at the same time deteriorate and pollute the natural and ecological environment. In addition, the iron ore slag discharged by iron and steel enterprises is also difficult to deal with. According to the test, these two materials contain higher SiO 2 、Al 2 o 3 , CaO, specific ingredients can be used to stimulate its gelling properties and be used to make lightweight wall...
