Embodiment 1

[0030] In the slag activator, the addition ratio of titanium gypsum and calcium carbide slag is 75%:25%. The slag activator in the slag masonry powder accounts for 18% of the mass of the slag masonry powder, and the slag accounts for 82% of the mass of the slag masonry powder. %.

[0031] The building block prepared by slag masonry powder has a strength of ≥10MPa in 3 days and a strength of ≥20MPa in 28 days, reaching the standard of low-grade cement.

Embodiment 2

[0033] In the slag activator, the addition ratio of titanium gypsum is 5% and calcium carbide slag is 95%. In the slag masonry powder, the slag activator accounts for 18% of the mass of the slag masonry powder, and slag accounts for 82% of the mass of the slag masonry powder.

[0034] Building blocks made from slag masonry powder set superfast and have insufficient strength development

Embodiment 3

[0036] Among the slag activators, titanium gypsum accounted for 98% and calcium carbide slag 2%. In slag masonry powder, slag activator accounted for 18% of the mass of slag masonry powder, and slag accounted for 82% of the mass of slag masonry powder.

[0037] The setting time of building blocks prepared by slag masonry powder is too long, the slag is not sufficiently intensified, the activity cannot be exerted, and the strength is low

Abstract

The invention relates to a slag activation agent and a manufacturing method thereof, and slag masonry powder and a manufacturing method thereof, and belongs to the field of preparation of building materials from mineral wastes. According to the technical scheme, the slag activation agent comprises titanium gypsum and carbide slag, the titanium gypsum accounts for 5-98% of the total mass, and the carbide slag accounts for 2-95% of the total mass. According to the invention, the industrial wastes such as the slag, the titanium gypsum and the carbide slag are used as building raw materials, so that the industrial waste slag of waste minerals is recycled, and the aim of environmental protection is fulfilled; the waste part is accumulated for a long time, the product is effectively utilized, and economic benefits are achieved; and moreover, the carbide slag and the blast furnace slag are comprehensively utilized as building complementary materials, so that the quality requirements of building materials are met.

Description

technical field [0001] The invention relates to slag intensification and its manufacturing method, slag masonry powder and its manufacturing method, and belongs to the field of building materials prepared from mineral waste. Background technique [0002] Titanium gypsum is the industrial waste mud produced by the production of titanium dioxide in chemical plants. It has a water content of about 40-55%, is non-toxic, has a high viscosity, and is iron red. Because it contains sulfur trioxide similar to gypsum, it is called "titanium gypsum" for short. . According to the analysis of the chemical composition of titanium gypsum, it can be completely applied to cement production. However, due to the high viscosity of this type of solid waste, the site occupied by wet materials entering the factory is too large, the viscosity is high, and the accumulation will collapse. When drying, it adheres to the dryer, blocks the discharge port, sticks to the belt, and sticks to the elevator....
