Technology for producing slag micro powder and application of slag micro powder in cement production

Abstract

The invention discloses a technology for producing slag micro powder and application of the slag micro powder in cement production. The cement comprises the following raw materials in part by weight: 25 to 30 parts of slag micro powder, 45 to 55 parts of clinker, 3 to 8 parts of desulfurized gypsum, 5 to 10 parts of coal gangue, and 5 to 10 parts of fly ash. The technology is low in investment and quick in response, a large quantity of blast furnace slag can be digested, and the produced cement product has excellent performance. When the slag micro powder is applied to common cement concrete, the consumption of the cement can be reduced, and the cost of the concrete is reduced.

Description

technical field [0001] The invention belongs to the field of cement manufacture, and in particular relates to a technology for producing cement by using slag. Background technique [0002] Based on the dense distribution of iron-making enterprises around Xujiagou and Shuiye Town, the applicant found that a large amount of granulated blast furnace slag, a by-product of the iron-making industry, was not fully utilized and seriously occupied land. The blast furnace slag was small, and the amount of slag discharged from the blast furnace was very large. At that time, the consumption of cement enterprises was very limited. These ironworks had to transport the slag outside the factory. When the wind blows, it will fly everywhere, and the river bed will be blocked by water washing in rainy days, seriously damaging the local ecological environment. In view of the increasingly serious situation, according to the cement production technology and several years of exploration, we took ...
