Limestone used in asphalt mixing plants
Brief Introduction
Recent years, most of the domestic mine crushing and industrial sand making plants produce a large amount of limestone powder waste (high limestone powder content) in the production process, which not only pollutes the environment but also wastes raw materials, so how to turn limestone waste into treasure? It is imperative to seek a reasonable solution. domestic research shows that the use of limestone powder as admixture in concrete has the effect of improving concrete structure, enhancing concrete workability, and improving the resistance of concrete to sulfate attack at low temperatures.
GBM provide the complete solution of limestone powder preparation system for concrete plant. As a manufacturer of grinding equipment, GBM has established hundreds of limestone powder-to-batch system production lines in more than 120 countries and regions, which include Southeast Asia, Eastern Europe, South America, the Middle East and Africa.
According to the new《JGJ/T 318-2014 limestone powder in concrete application technical specifications》, 《 GB 50164 concrete quality control standards》 and other national and industrial standards.
