Abstract

The invention discloses a non-autoclaved lightweight thermal insulation particle aerated concrete block and a preparation method thereof. The aerated concrete block comprises the following components:50 to 100 parts of cement, 0 to 37.5 parts of fly ash, 0 to 12.5 parts of superfine slag powder, 0 to 50 parts of light particles, 2 to 8 parts of a foaming agent, 0 to 5 parts of a coagulation accelerator, 0.025 to 0.175 part of a foam stabilizer, 0.2 to 1.4 parts of a water reducing agent, 0.1 to 0.7 part of a water repellent, 0 to 0.6 part of fibers and 30 to 60 parts of water. The aerated concrete block has the advantages of light weight, heat preservation and insulation, energy conservation, high strength, simple maintenance process and low cost, and solves the problems of non-ideal heatpreservation and insulation performance and complex maintenance process of the existing aerated concrete block.

Description

technical field [0001] The invention relates to the technical field of preparation of aerated concrete blocks, in particular to an autoclaved lightweight heat-preserving granular aerated concrete block and a preparation method thereof. Background technique [0002] According to forecasts, the world's energy demand is increasing by 2% year by year, and a large amount of energy consumption will have a huge impact on the environment, economy, and people's lives. For my country, building energy consumption accounts for about 30% of my country's total energy consumption, which is the main growth point of my country's energy consumption. Among them, wall energy saving is the core issue of building energy saving. The development of new wall materials with light weight, high strength, good thermal insulation performance, and comprehensive functions is not only the general trend of wall material development, but also the need to ensure sustainable economic and social development. ...
