Embodiment 1

[0127] Production of Light Aggregate Concrete Hollow Slabs

[0128] 1. Crushing and screening of raw materials. The raw materials that do not meet the formula requirements are first crushed and screened. For example, the slag should be crushed to the allowable particle size range in the formula with a pulverizer.

[0129] 2. Ingredients. According to the recipe requirements, after the various raw materials are measured, such as the lifting bucket of the mixer, they are injected into the mixing drum for stirring. And repeat the batching to ensure the continuous work of the mixer. The formula ratio (percentage by weight) is as follows:

[0130] Slag - 30%, particle size below 8mm.

[0131] Fly ash - 35%, aggregate diameter below 2mm.

[0132] Construction waste - 15%, particle size below 8mm, powder content below 10%.

[0133] Cement - 20%. According to the requirements of wall materials for different purposes, rapid hardening sulfoaluminate cement or modified Portland ce...

Embodiment 2

[0146] Inner wall panels: Mainly develop two kinds of industrial waste slag light aggregate wall panels and coal gangue wall panels after spontaneous combustion. The invention can improve the sound insulation performance of the product to ≥42dB and reduce the shrinkage rate to ≤0.05mm / m.

[0147] 1. Crushing and screening of raw materials. The raw materials that do not meet the formula requirements are first crushed and screened. For example, the slag should be crushed to the allowable particle size range in the formula with a pulverizer.

[0148] 2. Ingredients. According to the recipe requirements, after the various raw materials are measured, such as the lifting bucket of the mixer, they are injected into the mixing drum for stirring. And repeat the batching to ensure the continuous work of the mixer. The formula ratio (percentage by weight) is as follows:

[0149] Industrial waste - 40%, particle size below 8mm.

[0150] Coal gangue after spontaneous combustion - 40%,...

Embodiment 3

[0164] Exterior wall panels: Mainly develop construction waste sandstone wall panels. Improve product density, strength, impermeability, freeze-thaw resistance, etc. Strength ≥ 10Mpa, impermeability ≤ 10mm, freeze-thaw ≥ 15 times.

[0165] 1. Crushing and screening of raw materials. The raw materials that do not meet the formula requirements are first crushed and screened. For example, the slag should be crushed to the allowable particle size range in the formula with a pulverizer.

[0166] 2. Ingredients. According to the recipe requirements, after the various raw materials are measured, such as the lifting bucket of the mixer, they are injected into the mixing drum for stirring. And repeat the batching to ensure the continuous work of the mixer. The formula ratio (percentage by weight) is as follows:

[0167] Sand, gravel - 40%, particle size below 8mm.

[0168] Construction waste - 40%, aggregate diameter below 2mm.

[0169] Cement - 20%. According to the requiremen...

Abstract

The invention provides a light wall slab, which is producing by the following materials in weight percentage: 30 percent of slag with the grain size of less than 8mm, 35 percent of fly ash with the pellet diameter of less than 2mm, 15 percent of construction waste with the grain size of less than 8mm and the power content of less than 10 percent, and 20 percent of cement; moreover, a water reducing agent, a water repellent and an accelerating agent are added into the materials, and water of which the weight accounts for the total weight of the slag, the fly ash, the construction waste and the cement dry material is between 17 and 22 percent is added into the mixture; and the production process comprises the following: crushing raw materials, screening, preparing materials, mixing and stirring the materials, extruding by a slat extruder, curing, cutting, lifting the slab and pile-curing. The light wall slab has the advantages of improving the construction speed of single buildings, saving energy, increasing usable floor areas, meeting building requirements on various levels and prompting the wall material to develop towards industrialization and modernization of the housing industry. The light wall slab can promote the development of internal wall slabs and external wall slabs, and increase types of heat preservation wall slabs. Compared with expanded perlite, the sound insulation property of the industrial residue light aggregate wall slab is improved by more than 30 percent.

Description

technical field [0001] The invention belongs to the building material manufacturing industry, and relates to a lightweight wallboard and its manufacturing process, in particular to a kind of construction waste, slag or coal gangue after spontaneous combustion, fly ash, cement, adhesive, water and other substances processed, Lightweight wallboards and their manufacturing processes formed by manufacturing processes such as proportioning, mixing, and molding. Background technique [0002] At present, in the production of similar light-weight wall materials in our country: the variety of wallboards is single, and the quality level of products is low. In recent years, the wallboard industry has developed to an initial stage, and most wallboard manufacturers use molds to produce water-expanded perlite wallboards. The production process and equipment of this kind of wallboard are simple, the quality of the product is low, the sound insulation can only reach 30dB, and the shrinkage...
