1. The main chemical components of mineral powder are CaO, SiO2, Al2O3, Fe2O3, etc., which play a filling role in the asphalt mixture, and the purpose is to reduce the voids of the asphalt concrete. It is sometimes called filler, which can reduce the amount of cement, Improve the workability of concrete and reduce the heat of hydration.1TfUltrafine Grinder, Ultrafine Mill For Sale

3. The content of mineral powder is usually expressed by the powder-oil ratio. The larger the powder-oil ratio, the stronger the high-temperature rutting resistance of asphalt concrete, and the smaller the powder-oil ratio, the better the low-temperature crack resistance of the concrete.1TfUltrafine Grinder, Ultrafine Mill For Sale

4. After concrete is mixed with ground mineral powder, it can delay the hydration speed of the cementitious material and prolong the setting time of concrete. This property is beneficial to the transportation and construction of concrete in high temperature season.1TfUltrafine Grinder, Ultrafine Mill For Sale
