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 a glass fiber autoclaved lightweight concrete (ALC) slab and a preparation method thereof. The preparation method comprises the following steps: a, carrying out primary mixing on oleic acid, triethanolamine and water to prepare soluble oil; b, carrying out secondary mixing on an aluminum source, a foaming agent and water to prepare an aluminum powder suspension; c, in the presence of a magnetic field of which the magnetic field strength is 0.002-0.003T, carrying out tertiary mixing on cement, lime, fly ash, gypsum, a glass fiber, phenolic resin, red brick particles, iron oxide and water, adding the soluble oil and the aluminum powder suspension and carrying out quartus mixing to prepare a slurry; and d, weaving reinforcing steel bars of which surfaces are coated with asphalt into reinforcing steel bar meshes, pouring the slurry among multilayer reinforcing steel bar meshes and then aerating to prepare the glass fiber ALC slab, wherein the aluminum source is aluminum powder or aluminum paste and the foaming agent is one or more of nekal, peregal, saponin powder, paraffin soap and washing powder. The glass fiber ALC slab has the advantages of 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 (ALC) board and a preparation method thereof. Background technique [0002] Autoclaved aerated concrete is a building material with cement, lime, and fly 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 air-entra...
