Highway Mineral Powder

Guidance
Limestone tailings, stone powder, leftover bits and pieces are regarded as traditional wastes. It has become a trend to make concrete mixed with stone powder after grinding. A way of turning “waste” into treasure in green ecological mine is more and more favored by green mine project, aggregate recycling project, road and bridge project and high performance concrete project.
Domestic research results (GBT-30190-2013-limestone powder concrete) show that the use of limestone powder as admixture in concrete can improve the concrete structure, enhance the workability of concrete and improve the sulfate resistance of concrete at low temperature.
Technical Specifications for Construction of Highway Asphalt Pavements (JTG F40-2004) also stipulates the fineness of mineral powder of highway asphalt concrete. The research shows that mineral powder plays a filling role in asphalt mixture. The purpose is to reduce the void of asphalt concrete, reduce the amount of cement, improve the workability of concrete and reduce the heat of hydration. Mineral powder and asphalt form asphalt mortar together, which improves the strength and stability of asphalt concrete.
GBM is a high-tech enterprise which integrates crushing and grinding equipment. It can provide integrated solutions of design, supply and service. We have obtained extensive cooperation with well-known road and bridge companies and concrete mixing station companies in China. The projects are spread over more than 60 countries and regions at home and abroad.
Concrete mixing station: 325mesh D85
