China is a large country of basic construction in the world, and the annual consumption of sand and gravel in China is up to 208 hundred million tons and is increased by 6.4 percent on year-by-year basis under the drive of the high-speed development of the construction industry in 2019. With the trend of increasing the natural sandstone resources and the increasing enhancement of environmental protection, the quantity of sandstone collection points and mines is greatly reduced, the supply of sandstone is slightly tense, and the average price of sandstone rises by 10% at the end of the year. In 2020, the market has the state of steady increase of demand and continuous improvement of sand and stone supply, 220 hundred million tons of mineral slag are expected to be produced in 2020 in China, the yield is increased by 13 hundred million tons every year, and more than 0.2 ton of mineral slag micro powder can be produced per 1 ton of machine-made sand produced.
The basalt slag micropowder is solid basalt slag micropowder produced in the production process of producing broken stones and machine-made sand for buildings, and if the basalt slag micropowder is not treated and comprehensively utilized and is stacked in the open air, not only can a large amount of land be occupied, but also dust can cause air pollution. Therefore, the open stacking of a large amount of slag micro powder is difficult to treat in the mine environment. At present, a great deal of research is carried out on utilization and harmless treatment of basalt slag micro powder at home and abroad, but the utilization and the harmless treatment of the basalt slag micro powder are mainly buried basically, a great deal of land is occupied, and the purposes of fundamentally eliminating environmental pollution and fully utilizing the basalt slag micro powder cannot be achieved; along with the continuous expansion of cities in China and the continuous improvement of the living environment of people, the urban landscaping needs to take a large amount of soil from rural cultivated lands, thereby occupying a large amount of land resources.
