Problems solved by technology

Adding ceramsite to air-entrained concrete can reduce the bulk density of concrete, reduce the floor load, and also have the functions of heat insulation, sound insulation and sound absorption, antifreeze and impermeability, and environmental protection. However, ceramsite is a hollow and lightweight Aggregate, during the mixing process, due to the large proportion of the slurry, the ceramsite is easy to float, resulting in uneven distribution and product defects

Embodiment Construction

[0013] specific implementation plan

[0014] The present invention will be described in detail below through specific examples.

[0015] A ceramsite aerated block added with shell powder, made of the following raw materials in parts by weight (kg): shell powder 14, ceramsite 50, fly ash 27, quicklime 12, cement 20, aluminum powder 0.5, gypsum powder 4. Silt 20, calcium lignosulfonate 0.5, iron powder 3, nano-aluminum oxide 5, carbon black 3, absolute ethanol 16, appropriate amount of water;

[0016] A ceramsite aerated block added with shell powder according to the present invention is made by the following specific steps:

[0017] (1) Add iron powder, carbon black and nano-alumina to anhydrous ethanol containing 0.5% silane coupling agent KH-550, and ultrasonically disperse evenly. After drying, mix them with ceramsite and add them to the sintering furnace. Sintering for 2 hours at °C for subsequent use;

[0018] (2) Soak the sintered ceramsite prepared in step (1) in a wa...

Abstract

The invention discloses a ceramsite aerated building block added with shell powder, which is characterized by being prepared from following raw materials, by weight, 12-14 parts of shell powder, 30-50 parts of ceramsite, 15-30 parts of fly ash, 8-12 parts of quick lime, 16-20 parts of cement, 0.2-0.5 parts of aluminum powder, 2-4 parts of gypsum powder, 15-20 parts of sludge, 0.3-0.5 parts of calcium lignosulphonate, 1-3 parts of iron powder, 3-5 parts of nano aluminum oxide, 2-4 parts of carbon black, 15-20 parts of anhydrous ethanol and a proper quantity of water. A technical method in the invention solves the problem that ceramsite is liable to be crushed during processing and is non-uniform in distribution in a slurry material. The added shell powder can regulate moisture of the building block, so that the building block is not liable to crack, thereby achieving excellent indoor living condition under proper moisture. The building block is high in waste recycle rate, is simple in process, is low in cost, is environment-protective and saves natural sources, and is valuable to popularize.

Description

technical field [0001] The invention relates to the field of aerated blocks, in particular to a ceramsite aerated block added with shell powder. Background technique [0002] In the past, the masonry materials used in house construction in my country mostly used clay sintered bricks, but in recent years, due to the protection of the soil, the use of clay sintered bricks has been gradually reduced, and the policy of prohibiting the use of clay sintered bricks has been introduced in some areas In execution. Therefore, looking for a masonry material that replaces clay fired bricks has become a top priority in the construction industry. A series of masonry materials such as lime-sand bricks, hollow masonry, and cement bricks are used in construction. Aerated concrete blocks have also entered people's field of vision, and gradually become a new favorite in the construction industry relying on their own characteristics. Air-entrained concrete blocks have numerous small, independ...
