Embodiment Construction
[0007] The raw materials used in the present invention are: by weight ratio, 270 parts of ceramsite, 270 parts of slag, 100 parts of cement, 15 parts of fly ash, steel fiber and glass fiber; first ceramsite and slag are saturated with water, cement and 50 parts Parts of water are mixed to make cement slurry, and then the water-soaked ceramsite and slag, cement slurry and fly ash are mixed and stirred evenly to make a mixed slurry, and then 1.2% of the mixed slurry volume is added to the mixed slurry Steel fibers and glass fibers with a volume of 2.4% of the mixed slurry are mixed evenly and poured into the mold, solidified and demolded; the maximum diameter of the ceramsite and slag used is 10mm, and the specification of the steel fiber is 70mm in length and 0.65mm in diameter. The length of the fiber was 30 mm.
[0008] After testing, the drying shrinkage value of the wallboard of the present invention is 0.56mm / m within half a month, and 0.58mm / m within half a year, which ca...

Abstract
High-intensity light wallboard, the used materials are: according to the weight ratio: ceramicite 235 - 300, slag 235 - 300, cement 120 - 80, coal ash 10-20 and steel fiber; first dipping the ceramicite and the slag in water, mixing the cement and 45-55 water and preparing cement slurry, then mixing and stirring the water dipped ceramicite and slag, cement slurry and coal ash uniformly and preparing mixed slurry, then adding steel fiber into mixed slurry which volume is 0. 15%-2. 4% of mixed slurry volume, stirring uniformly and casting into die, preparing the plate after solidifying, and demoulding; maximum diameter of used ceramicite and slag is 10 mm, the length of steel fiber is 50 - 75mm and the diameter is 0. 6 -0. 7 mm. It has advantages of high strength, small drying shrinkage, no cracks generated between wallboards, no efflorescence when meets water and good sound insulation, its weight is light, the board is thin, it can be planed, sawed and drilled, it is easy to be punched and embedded hanger, it has non-inflammability, the fire prevention performance is good, it uses slag and coal ash as raw materials, it is benefit for environmental protection.
Description
technical field [0001] The invention relates to a lightweight wallboard for construction, especially a high-strength lightweight wallboard. Background technique [0002] At present, light-weight wallboards are widely used in building construction, but the existing light-weight wallboards have low strength, or large drying shrinkage, and cracks are easy to occur between wallboards, or they are easy to pulverize when exposed to water, or the sound insulation effect is not good. Shortcomings. Contents of the invention [0003] The object of the present invention is to provide a high-strength lightweight wallboard with high strength, small drying shrinkage, no cracks between wallboards, no pulverization when exposed to water, and good sound insulation effect. [0004] Technical solution of the present invention is: [0005] The raw materials used in the present invention are: according to the weight ratio, 235-300 parts of ceramsite, 235-300 parts of slag, 80-120 parts of ce...
