Abstract

The invention discloses a modified nano mineral powder-containing aerated brick. The aerated brick is prepared from the following raw materials by the conventional process for preparing the aerated brick: 25 to 30 weight parts of carbide slag, 5 to 10 weight pars of cement, 10 to 15 weight parts of quick lime, 5 to 10 weight parts of modified nano mineral powder, 5 to 10 weight parts of shell powder, 3 to 5 weight parts of gypsum, 0.05 to 0.1 weight part of aluminum powder, 0.002 to 0.008 weight part of lauryl sodium sulfate, 0.03 to 0.08 weight part of tea seed cake powder, 0.3 to 0.5 weight part of soda ash, 0.5 to 0.8 weight part of expanded vermiculite powder, 0.3 to 0.5 weight part of zinc stearate, 0.01 to 0.03 weight part of aluminum hydroxide, 0.05 to 0.1 weight part of sodium diacetate and an appropriate amount of water. By adding the nano mineral powder, the volume weight of the brick, and the energy consumption are reduced; the brick is high in thermal insulation performance and sound insulation performance; compared with the conventional aerated brick, the aerated brick has the advantages that the thermal insulation performance and the sound insulation performance are improved obviously; the raw materials are mixed according to an optimized formula; and the intensity and the freezing resistance of the brick are improved obviously.

Description

Technical field [0001] The present invention involves the field of brick, which is precisely a gas -added brick containing modified nano -mineral powder. Background technique [0002] Aerated concrete is a new type of wall building material. It is unique that it is a very light new building wall material with a very light insulation and insulation.Qi concrete technology began one hundred years ago, and this technology in my country began to be relatively late, 40 years behind abroad. However, the development of the gas -added concrete industry in my country is indeed very fast.At present, the level of gas -added concrete technology technology can already reach the international advanced level. [0003] The biggest advantage of gas -added concrete is to save land resources without waste a lot of cultivated land, and its sources of raw materials are very extensive. Gray sand, slag, stabs, and coal gangsters are all raw materials for gas -added concrete.In addition, the performance ...
