Mineral powder is a general designation of stone powder and its substitutes that meet the engineering requirements. It is the product of crushing ore, a step of ore processing and smelting, and one of the most important steps. The hydrophilic coefficient of mineral powder is the ratio of the expansion volume of unit mineral powder in the same volume of water (polar molecules) and kerosene (nonpolar molecules). In highway engineering, the mineral powder whose hydrophilic coefficient is less than 1 is called alkaline mineral powder.

Nowadays, energy and environment have become the focus of the world, and every country and region is making great efforts

Thermal insulation mortar

Thermal insulation mortar

Promote energy conservation and emission reduction. In China, 65% control index of building energy conservation is proposed as a national mandatory index, and the external wall insulation system plays an important role in the field of building energy conservation. The implementation of national building energy conservation index makes the external wall insulation system widely used, and the amount of insulation mortar matching with it also increases dramatically. Cement is simply used as inorganic cementitious material Although the thermal insulation mortar can also meet the requirements of relevant standards, in order to pursue better mortar performance and economic benefits, the test of thermal insulation mortar production with mineral dressing instead of part of cement is carried out and better results are obtained. Although the addition of mineral powder reduces the tensile bond strength of mortar to a certain extent, it still meets the standard requirements. The amount of water absorption and the compression ratio of the plaster mortar are improved by adding a proper amount of mineral powder. The safety of external insulation is more effectively guaranteed. Because the price of mineral powder is higher than that of cement, the economic benefit of the production formula of this kind of mix proportion is obvious when choosing the right mix alligator. Large dry mixed mortar manufacturers can also consider using bulk cement and mineral powder for production, further reducing the cost.
