Abstract

The invention relates to a high-strength and high-performance mineral admixture for high-strength and high-performance concrete and a production method thereof. The particle size of 97% of the total weight of the high-strength and high-performance mineral admixture is smaller than 20 microns. A closed-loop microsphere tube mill with a superfine powder concentrator is used for grinding. The production method has the advantages of industrial feasibility, energy conservation and the like. The high-strength and high-performance mineral admixture not only comprehensively utilizes a large amount of industrial waste residues in the industries of metallurgy, coal mine, thermal power, garbage treatment and the like, but also fundamentally improves the constructability of concrete and multiplies the strength and durability.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a high-strength and high-performance mineral admixture for high-strength and high-performance concrete and a production method. Background technique [0002] As we all know, concrete can be mixed with mineral admixtures that meet the relevant national standards of the host country to reduce the cost of concrete and comprehensively utilize industrial waste. However, after conventional methods add mineral admixtures to concrete, certain properties of concrete, such as : Strength, bleeding, anti-segregation ability, frost resistance, anti-carbonation ability, etc. are all reduced to varying degrees, and the proportion of mineral admixtures instead of Portland cement is low. Contents of the invention [0003] The problem to be solved by the present invention is to provide a high-strength and high-performance mineral admixture whose contribution to all comprehensive properties (con...
