Problems solved by technology

The autoclaved aerated concrete block or plate made of autoclaved aerated concrete has the characteristics of low density, fire resistance, fire prevention, sound insulation, heat insulation and heat preservation. However, the building materials made of autoclaved aerated concrete are mechanically In terms of strength, it is difficult to reach the mechanical strength of other building materials such as stone and red bricks. Once natural disasters such as earthquakes occur, buildings made of autoclaved aerated concrete will be prone to collapse.

Abstract

The invention discloses glass fiber autoclaved aerated concrete and a preparation method thereof. The method comprises the following steps: A, performing first mixing of oleic acid, triethanolamine and water for preparing soluble oil; B, performing second mixing of an aluminum source, a foaming agent and water for preparing aluminum powder suspension; C, in the presence of a magnetic field with the magnetic field strength of 0.002-0.003T, performing third mixing of cement, lime, fly ash, gypsum, glass fiber, phenolic resin, red brick particles, Fe3O4 and water, then adding the soluble oil and the aluminum powder suspension for fourth mixing and casting, and aerating for preparing the glass fiber autoclaved aerated concrete; the aluminum source is aluminum powder or aluminum paste, and the foaming agent is one or more substance of nekal, peregal, saponin powder, paraffin soap and washing powder. A building material prepared from the fiber glass autoclaved aerated concrete has excellent mechanical strength, density and frost resistance.

Description

technical field [0001] The invention relates to autoclaved aerated concrete, in particular to a glass fiber autoclaved aerated concrete and a preparation method thereof. Background technique [0002] Autoclaved aerated concrete is a building material with cement, lime, silica fume and coal ash as the main raw materials. The autoclaved aerated concrete block or plate made of autoclaved aerated concrete has the characteristics of low density, fire resistance, fire prevention, sound insulation, heat insulation and heat preservation, but the building materials made of autoclaved aerated concrete are mechanically In terms of strength, it is difficult to reach the mechanical strength of other building materials such as stone and red bricks. Once natural disasters such as earthquakes occur, buildings made of autoclaved aerated concrete will be prone to collapse. Contents of the invention [0003] The object of the present invention is to provide a glass fiber autoclaved aerated ...
