Abstract
Description
technical field
[0001] The invention relates to a lightweight board for construction, in particular to a lightweight board with fly ash, which is suitable for assembling inner or outer walls of buildings and belongs to the field of building materials. Background technique
[0002] Fly ash is the fine powder waste residue produced during the power generation process of thermal power plants. The annual discharge of fly ash in my country is about 100 million tons. In order to save energy, my country encourages the use of fly ash to produce building materials. The utilization rate of coal only reaches about 30% of its total emissions. In terms of building materials, most of them are used to produce low-end products such as fly ash blocks or insulation bricks. Although these products have certain strength, they have low toughness and are easy to Broken, it can only be used for the interior and exterior walls of non-load-bearing walls, and cannot be used in parts that require high s...
Examples
Embodiment 1
[0015] Embodiment 1, fly ash lightweight board, the raw material composition of described lightweight board includes fly ash, cement, perlite, and described raw material composition also includes polypropylene fiber, water reducer, acrylic acid emulsion, foaming agent and Water, the weight configuration ratio of each component in the light board raw material is: 50 parts of fly ash, 20 parts of cement, 8 parts of perlite, 0.3 part of polypropylene fiber, 0.5 part of water reducer, 2 parts of acrylic emulsion, hair 0.2 parts of foaming agent and 19 parts of water. The production process is to mix and stir the above-mentioned raw materials. After stirring evenly, roll pressing is carried out first, and then vibration and pressure molding are carried out to make light-weight boards.
[0016] After experimental research, the mechanical properties of the product are shown in the table:
[0017]
[0018] The light board has been tested by the standard, and its mechanical p...
