Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] The preparation process of basalt machine-made sand dry-mixed mortar in the following examples is:

[0019] (1) Dry and dedust the machine-made sand in the raw materials, control the water content of the machine-made sand to <0.4%, mud content <1.0%, and particle size <5mm;

[0020] (2) Mix and stir the components in the raw materials evenly, measure and bag them to obtain dry-mixed basalt sand mortar; wherein, the raw materials include 10.2 to 18.3 parts of cement, 1.8 to 3.2 parts of fly ash, and 77.7 to 87.4 parts of basalt Machine-made sand, 0.4-0.8 parts of admixture; or the raw materials include 10.2-18.3 part...

Abstract

The invention discloses basalt machine-made sand dry-mixed mortar and a preparation method thereof. The preparation method comprises the following steps: drying machine-made sand in a raw material, and controlling the moisture content in the machine-made to be less than 0.4 percent, the silt content to be less than 1.0 percent and the grain diameter to be less than 5mm; then uniformly mixing and stirring all components in the raw material, metering and bagging, thus obtaining the basalt machine-made sand dry-mixed mortar, wherein the raw material is prepared from 10.2 to 18.3 parts of cement,1.8 to 3.2 parts of pulverized fuel ash, 77.7 to 87.4 parts of basalt machine-made sand and 0.4 to 0.8 part of an additive. The basalt machine-made sand dry-mixed mortar disclosed by the invention isprepared by using the basalt machine-made sand locally produced in Lanzhou to replace original river sand and mixing with the cement, the pulverized fuel ash and the additive special for mortar and belongs to application of new materials, performance indexes of the basalt machine-made sand dry-mixed mortar meet the requirements, the technology is simple, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a basalt machine-made sand dry-mixed mortar and a preparation method thereof. Background technique [0002] With the rapid development of my country's construction industry, traditional construction mortar is a building material that is mixed with cement and river sand and water on site. During the construction process, quality problems cannot be controlled, and it will cause dust pollution to the environment, which can no longer adapt to the development of the market. need. In order to adapt to the development of the construction industry, the advantages of dry-mixed mortar are becoming more and more obvious, and it has become the general trend of development to replace traditional construction with dry-mixed mortar. Like commercial concrete, dry-mixed mortar has the characteristics of centralized production and unified supply, and at the same time has the...
