Flyash : well be used for concrete brick production
It refers to the fine ash collected by the flue gas after the coal combustion burned. a major solid waste from coal-fired power plants.
Advantages : mixed with flyash in the concrete saves a large amount of cement and fine aggregate. Improve the workability of concrete mixing. Enhance the permeability of concrete brick. Reduce the creep of concrete. Reduce the hydration heat, heat expansion. Improve the ability of concrete permeability. Increase concrete modification.
3 Grade flyash :
National standard level 1: adopting the high quality of flyash and high-efficiency water reducing agent of composite technology in the production of high-grade concrete in modern concrete technology is developing rapidly in the country.
National standard level 2: especially suitable for the preparation of pumping concrete, mass concrete, the impermeability of concrete structure, sulfate resistance of concrete and soft water erosion resistance and underground, underwater engineering concrete, concrete grouting concrete, and RCC
National standard level 3: has good workability, pumpability, impact-resistant ability improves, frost resistance enhancement, etc.
Flyash is a good raw material to produce concrete blocks, it can save the cost of raw materials, and also can do high-quality blocks, it is the good choice of the customers.
