Abstract
The invention relates to a desulfurization gypsum block, belonging to a building material. A mineral admixture comprises quick lime, white cement and coal ash, the weight percentage of desulfurization gypsum is 78.6%, the weight percentage of SC gypsum retarder is 0.2%, the weight percentage of the mineral admixture is 20%, and the weight percentage of glass fiber is 1.2%; the ratio of the quick lime to the white cement to the coal ash in the mineral admixture is 1:4:3, the water consumption for normal consistency is controlled to be 53%-58%; the coal ash is II-level coal ash, the white cement is P.C32.5, and the glass fiber is 15-20 mm. The advantages are as follows: the desulfurization gypsum block is mainly prepared from industrial residues, is applicable to a filler wall in a frame structure under a dry environment, can be prefabricated in a factory, and can achieve convenient and rapid construction. The desulfurization gypsum block prepared by the invention is remarkably improved in working performance and physical and mechanical properties, and has no radioactivity, hazardous substance or corrosivity.
Description
Technical field
The present invention relates to a kind of material of construction, particularly a kind of desulfurization gypsum block.
Background technology
At present industrial employed flue gas desulfurization produces a large amount of industrial residue-desulfurated plasters, stack these industrial residue-desulfurated plasters and taken a large amount of soils, good farmland, also there is not a kind of good treating method, bringing secondary pollution for our life, also is the pollution problem to environment that we need to be resolved hurrily.
Summary of the invention
Technical problem: the objective of the invention is to provide a kind of desulfurization gypsum block, utilizes industrial by-products, solves industrial residue to the pollution problem of environment.
Technical scheme: the object of the present invention is achieved like this: this desulfurization gypsum block comprises desulfurated plaster, SC calcium sulphate retarder, mineral admixture and glass fibre; Described mineral admixture is unslaked lime, white cement and flyash; Described desulfurated plaster is 78.6%, the SC calcium sulphate retarder is 0.2%, mineral admixture is 20%, glass fibre is 1.2%, all is weight percentage; The unslaked lime of described mineral admixture: white cement: flyash=1:4:3, consumptive use of water normal consistence is controlled at 53% ~ 58%; Described flyash is the II level, and white cement is P.C32.5, and glass fibre is 15mm ~ 20mm.
Beneficial effect: owing to adopted such scheme, owing to mix multi-component admixture again, obviously improved, improved serviceability and the physical and mechanical property of gypsum block, when satisfying national regulation, improved largely the performance of desulfurization gypsum block.Prepared desulfurization gypsum block, first final setting time are 49min and 68mi n, length, height and thickness deviation be respectively+2.3mm ,+1.4 mm and-0.6 mm, planeness is 0.9mm, apparent density is 1092 kg/m
3, 3d and 28d breaking load are respectively 7.06kN and 12.87kN coefficient of softening 0.69 all satisfies standard.Utilize desulfurated plaster to prepare desulfurization gypsum block for main raw material(s), solved desulfurated plaster take stocking and storing as main, the land occupation resource, environment is produced the problem of harm, for China's material of construction provides new variety, effectively controlled the problem of environmental pollution of China, for the modern urban construction of China provides novel starting material, selected material has desulfurated plaster and the flyash of larger component, has solved the problem of part industrial residue environmental pollution; For striding forward, the novel material of construction of China made outstanding contribution.
Advantage: this desulfurization gypsum block mainly is comprised of industrial residue, is applicable to the infilled wall of dry environment frame structures under action, and the production that can be prefabricated in the factory can realize convenient, fast construction.The prepared desulfurization gypsum block of the present invention significantly improves its serviceability and physical and mechanical property, "dead", unharmful substance and non-corrosiveness.Can realize improving the target that environment is saved the material of construction of the energy and innovation China, produce good Social benefit and economic benefit.
