Embodiment Construction

[0021] An environmentally friendly aerated brick containing coniferous wood pulp, which is made from the following weight (kg) raw materials: polypropylene fiber 2, polyvinyl alcohol 1, calcium carbonate 15, coniferous wood pulp 3, animal ashes 3, concentration 20% hydrogen peroxide 1, iron ore tailings 5, quicklime 1.5, sodium chloride 1.8, calcium lignosulfonate 3, modified waste concrete 35, cement 10, gypsum 3, water in proper amount;

[0022] Described modified waste concrete is made by the raw material of following weight (kg):

[0023] Waste concrete 30, sodium citrate 1.5, monoglyceride stearate 1, polyoxyethylene abietic acid 1.6, sodium dibutylnaphthalene sulfonate 1, sodium dodecylbenzene sulfonate 1, nano silicon dioxide 3, Lecithin 4;

[0024] The preparation method of described modified waste concrete is:

[0025] (1) The waste concrete was irradiated with ultraviolet rays for 12 hours, mixed with an appropriate amount of water, then added monoglyceride stearat...

Abstract

The invention discloses an environmental-friendly aerated brick containing needlebush pulp. The environmental-friendly aerated brick containing needlebush pulp is prepared from the following raw materials in parts by weight: 2-4 parts of polystyrene fiber, 1-3 parts of polyvinyl alcohol, 13-15 parts of calcium carbonate, 2-3 parts of needlebush pulp, 2-3 parts of animal bone ash, 1-3 parts of 20-30% hydrogen peroxide, 3-5 parts of iron ore milltailings, 1-1.5 parts of quick lime, 1.8-3 parts of sodium chloride, 1-3 parts of calcium lignosulphonate, 23-35 parts of modified waste concrete, 10-15 parts of cement, 3-5 parts of gypsum and a proper amount of water. By virtue of hygroscopicity and good dispersibility of the needlebush pulp, the toughness of the concrete is improved. By applying industrial waste carbide slag to produce a wall body material, the strength and toughness of the brick are improved, and the double effects of governing environmental pollution and comprehensively and efficiently using wastes are achieved.

Description

technical field [0001] The invention relates to the field of aerated bricks, in particular to an environment-friendly aerated brick containing coniferous wood pulp. Background technique [0002] Aerated bricks are flexible because of their hollow properties, while the main body of the building is supported by reinforced concrete structures, and the bricks only play a filling role. When an earthquake occurs, the reinforced concrete structure will be deformed. If it is a solid brick, the reinforced concrete structure will have no place to expand and contract when it is deformed and backlogged, and it will burst and collapse. The use of hollow bricks can leave a good expansion space for reinforced concrete structures. [0003] Due to the poor compatibility of the materials, the existing aerated bricks tend to become brittle, the strength is not long enough, the service life is not long enough, and they are not environmentally friendly.
