Embodiment 1

[0031] Example 1. Phosphogypsum modified reinforced moisture-proof gypsum block, which is made of the following raw materials in proportion by weight;

[0032] 80 parts of hemihydrate gypsum;

[0033] 15 parts of superfine powder of gasified blast furnace slag;

[0034] 2 parts of activator;

[0035] 70 parts of water.

[0036] The activator is calcium oxide.

[0037] The hemihydrate gypsum is α-type hemihydrate gypsum.

[0038] The gasification blast furnace slag ultrafine powder is obtained by grinding the vitreous slag into ultrafine powder from the vitreous slag remaining in the gasification blast furnace produced by synthetic ammonia. The gasification blast furnace is a gasification blast furnace for producing ammonia.

Embodiment 2

[0039] Example 2. Phosphogypsum modified reinforced moisture-proof gypsum block, which is made of the following raw materials in proportion by weight;

[0040] 80 parts of hemihydrate gypsum;

[0041] 15 parts of superfine powder of gasified blast furnace slag;

[0042] 2 parts of activator;

[0043] 70 parts of water;

[0044] Fiber 3 servings.

[0045] The activator is calcium oxide.

[0046] The hemihydrate gypsum is α-type hemihydrate gypsum.

[0047] The fibers are glass fibers.

[0048] The gasification blast furnace slag ultrafine powder is obtained by grinding the vitreous slag into ultrafine powder from the vitreous slag remaining in the gasification blast furnace produced by synthetic ammonia. The gasification blast furnace is a gasification blast furnace for producing ammonia.

Embodiment 3

[0049] Example 3. Phosphogypsum modified reinforced moisture-proof gypsum block, which is made of the following raw materials in proportion by weight;

[0050] 40 parts of hemihydrate gypsum;

[0051] 6 parts of superfine powder of gasified blast furnace slag;

[0052] 0.5 parts of activator;

[0053] 20 parts of water.

[0054] The activator is calcium hydroxide.

[0055] The hemihydrate gypsum is β-type hemihydrate gypsum.

[0056] The gasification blast furnace slag ultrafine powder is obtained by grinding the vitreous slag into ultrafine powder from the vitreous slag remaining in the gasification blast furnace produced by synthetic ammonia. The gasification blast furnace is a gasification blast furnace for producing ammonia.

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 [0001] The invention relates to a block, in particular to a modified phosphogypsum reinforced moisture-proof gypsum block. Background technique [0002] Water gypsum is formed by heating phosphogypsum under different conditions to remove water from the structure. In the process of cement production, phosphogypsum is generally treated as solid waste, which contains fluoride, free phosphoric acid, P 2 o 5 Impurities such as phosphogypsum and phosphate are the main factors causing environmental pollution during the storage of phosphogypsum. The large stockpiling of phosphogypsum not only encroached on land resources, but also polluted the atmosphere, water system and soil due to wind erosion and rain erosion. Prolonged exposure to phosphogypsum may cause death or disease in humans. [0003] Gypsum blocks are mainly used as partition walls for masonry buildings. The existing gypsum blocks are made of industrial solid waste such as phosphogypsum or desulfuriz...
