High-performance foamed-concrete cement material and preparing method thereof

Abstract

The invention relates to a high-performance foamed-concrete cement material and a preparing method thereof. The high-performance foamed-concrete cement material is prepared from, by weight, 20-40 parts of mineral admixtures, 35-65 parts of cement, 2-4 parts of retarder, 6-12 parts of foaming agent, 1-3 parts of bubble wall reinforcing agent, 1-3 parts of foaming speed adjusting agent, 5-10 parts of magnesium hydrate, 5-10 parts of aluminium hydroxide and 5-15 parts of building mortar admixtures. The preparing method includes the step that the components are mixed to be even. Compared with the prior art, the concrete cement material is resistant to corrosion, high in strength, good in sound insulation and thermal insulation, excellent in fireproof performance and stable in performance, and is used at the high temperature, the service life is longer, the applications are extremely wide, mineral admixtures such as industrial waste residue fly ash can be used, the cement content is reduced, high pressure maintenance can not be used, and the more cost is saved; the preparing method is easy to operate, the investment cost is low, comprehensive utilization of resources is fully achieved, the cleaner production and environmentally friendly requirements are met, and the high-performance foamed-concrete cement material is quite suitable for large scale production.

Description

technical field [0001] The invention relates to the field of chemical materials, in particular to a concrete cement material and a preparation method thereof. Background technique [0002] The widespread use of concrete in construction has led people to try to improve the production efficiency and quality of concrete. With the development of commercial concrete industry and its technology, the role of cement, mineral admixtures, additives, etc. in the composition of concrete has been paid more and more attention. [0003] At present, the largest amount of domestic use is the dry discharge of fly ash in thermal power plants mixed into concrete. Although it can reduce the amount of cement, the quality variation coefficient of fly ash is large, which often leads to poor workability of concrete and large fluctuations in strength, making concrete The effect is not good. [0004] At present, there is still the case of adding foaming agent to cement, which is more suitable for gr...
