Abstract
The invention discloses an ardealite modified and strengthened damp-proof gypsum block which is mainly prepared by hemihydrate gypsum, vaporized slag ultra-fine powder, an activator and water. The strength of the block can be improved, the sound insulation, damp proofing and fire proofing effects are good, and meanwhile environmental pollution caused by chemical reaction can be avoided.
Description
Technical field
The present invention relates to a kind of building block, particularly a kind of phosphogypsum modification strengthens moistureproof gypsum block.
Background technology
Water gypsum is by phosphogypsum heat treated at different conditions, water in structure is sloughed and is formed.In the process of manufacture of cement, generally using phosphogypsum as solid waste process, wherein institute's fluoride, free phosphoric acid, P
2o
5, the impurity such as phosphoric acid salt is the principal element causing phosphogypsum to cause environmental pollution in the process of storing up.Storing up in a large number of phosphogypsum, has has not only occupied land resources, and due to the pollution of eroding, weathering causes air, water system and soil.Long contact time phosphogypsum, may cause death or the pathology of people.
Gypsum block is mainly as the partition wall of building building construction by laying bricks or stones, existing gypsum block utilizes industrial solid waste residue to be made as phosphogypsum or desulfurated plaster, bunt gypsum, fluorgypsum, the plaster of paris etc., has lightweight, heat-insulation and heat-preservation, builds advantage convenient and swift, that body of wall is attractive in appearance by laying bricks or stones.But there is the defect of insufficient strength, and sound insulation, waterproof and fp effect not very good.
Summary of the invention
The object of the invention is to, provide a kind of phosphogypsum modification to strengthen moistureproof gypsum block.The present invention can not only strengthen the intensity of building block, and sound insulation, protection against the tide and fp are effective, can avoid the environmental pollution that chemical reaction causes simultaneously.
Technical scheme of the present invention: phosphogypsum modification strengthens moistureproof gypsum block, it is made with the raw material of following weight parts proportioning;
