Abstract

The invention discloses an ore powder mixture, and a preparation method thereof, and belongs to the technical field of ore powder processing. The preparation method is capable of solving a problem inthe prior art that the using effect is poor because of the low activity of ore powder. The ore powder mixture comprises, by weight, 80 to 85 parts of blast furnace slag raw material raw material, 2.5to 5.5 parts of siliceous rock, 5 to 7 parts of hemihydrate gypsum, 2 to 4 parts of bone black, 0.8 to 1.4 parts of a surface modifier, 1.1 to 1.7 parts of an exciting agent, 0.4 to 0.6 part of a dispersant, 1.2 to 1.8 parts of organic silicone alkane. The ore powder mixture is relatively high in activity, is capable of increasing the compressive strength, the compactness, and the impervious capability of concrete in using, and is excellent in using effect.

Description

technical field [0001] The invention relates to the technical field of mineral powder processing and production, more specifically, it relates to a mineral powder mixture and a preparation process thereof. Background technique [0002] Mineral powder generally refers to the material powder obtained by crushing mined ore. It is mainly used as an admixture for concrete, which can effectively improve the compressive strength of concrete, improve the compactness and impermeability of concrete, and reduce the cost of concrete. [0003] A Chinese invention patent with publication number CN106746809A discloses a composite mineral powder and its preparation method, including the following components in parts by weight: 20-60 parts of limestone, 5-25 parts of phosphorus slag powder, 5 parts of steel slag powder ~25 parts, 5~25 parts of slag, 5~25 parts of clinker and 5~25 parts of gypsum. [0004] In the above-mentioned patent, the steel slag, phosphorous slag and slag are finely g...
