Embodiment Construction

[0009] An aerated brick for thermal insulation and load-bearing factory buildings, which consists of the following components in parts by weight: 12 parts of copper ore tailings, 35 parts of composite Portland cement, 12 parts of fly ash ceramsite, and 5 parts of shale ceramsite 5.2 parts of zirconium coupling agent, 2.5-3.5 parts of water glass, 3.5-4.5 parts of sodium lauryl sulfate, 2 parts of waterproofing agent, 5.8 parts of sawdust waste, 2.8 parts of nucleating agent, SY-G type high performance 1.4 parts of swelling anti-cracking agent, 95 parts of water;

[0010] According to the above parts by weight, the preparation method of the aerated brick is as follows: first feed copper ore tailings, composite Portland cement, sawdust waste, and water glass into a pre-heating machine with a steam pressure of 1.3Mpa and preheated to 115°C. Foaming, after 1.8h pre-foaming to obtain pre-foaming material; then fully stir the pre-foaming material with fly ash ceramsite, shale cerams...

Abstract

The invention discloses a heat preserving and bearing air-entrained brick for a factory building. The air-entrained brick is prepared from, by weight, 10-15 parts of copper ore tailings, 30-40 parts of composite Portland cement, 11-13 parts of fly ash ceramsite, 4-6 parts of shale ceramisite, 4.5-6 parts of a zirconium coupling agent, 2.5-3.5 parts of water glass, 3.5-4.5 parts of lauryl sodium sulfate, 1.5-2.5 parts of a waterproof agent, 5.4-6.2 parts of sawdust waste, 2.2-3.5 parts of a nucleating agent, 1.2-1.6 parts of an SY-G type high-performance expansion anti-cracking agent and 90-100 parts of water. According to the air-entrained brick, a design formula is further optimized, the technological process is simpler and more friendly to the environment, both a bearing function and a heat preserving function are achieved, and the existing air-entrained brick development requirements are met.

Description

technical field [0001] The invention relates to the field of building mortar, in particular to an aerated brick for heat-preservation and load-bearing workshops. Background technique [0002] Countries have done a lot of work in building design and construction, development and application of new building insulation materials, formulation and implementation of building energy-saving regulations, etc., while achieving considerable economic benefits, they have also improved the natural environment on which human beings live. Usually the bricks in the wall are non-load-bearing, hollow structure, easy to absorb water and crack when exposed to air for a long time, which requires further improvement in the formula design and manufacturing process of aerated bricks. Contents of the invention [0003] The purpose of the present invention is to provide an aerated brick for thermal insulation and load-bearing factory buildings. The design formula of the aerated brick is further opti...
