Lightweight aggregate gypsum particle and production method thereof

Abstract

The invention relates to a lightweight aggregate gypsum particle and a production method thereof. The lightweight aggregate gypsum particle is prepared by the following raw materials according to weight ratio: hemihydrate gypsum powder, lightweight aggregate, dilatant, cement and water. The preparation method of the lightweight aggregate gypsum particle comprises the following steps: the mixed and stirred raw materials are prepared into particle; the particle is solidified and dried into lightweight aggregate gypsum particle finished product. The lightweight aggregate gypsum particle prepared by the method has the advantages that the forming effect is great, the particle is easy to be dry, especially, the gypsum is easy to be adhered to the lightweight aggregate and the dilatant, the volume weight is light, the strength is high, and the cost is low. Building materials, such as lightweight building block, hollow block, brick and plate for construction, that prepared by the lightweight aggregate gypsum particle have the advantages that the sound insulation and heat preservation effects are good, the bulk density is low, the volume weight is light, especially the production technique is simple, the materials are not broken easily, the rate of finished products is high, the production cost is low, and the strength is high. Therefore, the materials are very applicable in construction industry.

Description

technical field [0001] The invention relates to a light aggregate gypsum particle and a manufacturing method thereof, which use gypsum and light aggregate as main raw materials and process it into granules to manufacture lightweight building blocks for construction. Background technique [0002] The lightweight blocks used in the current construction industry, especially the lightweight blocks made by the non-burning method, are usually made of light aggregates such as plant fibers, fly ash, plastic foam, perlite expansion, cement, and semi-hydrated materials. Gypsum and water are mixed together and then pressed into shape, but in use, if the gypsum and cement are mixed together, due to the different hardening time, the maintenance of block products is difficult, and the proper setting strength of cement is weakened. In light aggregates, organic raw materials such as plant fibers cannot be treated with anti-corrosion and anti-moth. For foamed materials in light aggregates, ...

Problems solved by technology

It is also possible to use clay or fly ash to add expansion matter to make granules, and then add it to cement to make blocks, but most of them have insufficient compressive strength and cannot meet the building requirements; or the bulk density exceeds the standard and cannot meet the architectural design. Indicators and sound insulation effects; or use a lot of reinforcement when making blocks, which increases the cost
