Fly ash application scope includes what
Fly ash mill application scope should be considered from the actual use of fly ash, its application scope mainly includes: cement industry and concrete engineering applications, applications in building products, as agricultural fertilizers and soil conditioners, recycling of industrial raw materials, as environmental protection materials, as raw materials for the production of raw materials, as raw materials for papermaking, etc., which has the widest range of applications in the construction industry and the largest amount of dosage.
Adding fly ash in concrete saves a lot of cement and fine aggregate; reduces water consumption; improves the compatibility of concrete mix; enhances the pumpability of concrete; reduces the creep of concrete; reduces the heat of hydration and thermal expansion; improves the impermeability of concrete; and increases the modification of concrete.
National Standard Grade I Concrete: The new modern concrete technology of using high-quality fly ash and high-efficiency water-reducing agent composite technology to produce high grade concrete is developing rapidly in the country.
National Standard Grade II Concrete: High-quality fly ash is especially suitable for the preparation of pumping concrete, mass concrete, impermeable structural concrete, sulfate-resistant concrete and soft-water erosion-resistant concrete, as well as underground and underwater engineering concrete, slurry concrete and crushed concrete.
National Standard Grade III Concrete: Fly ash concrete has the advantages of good compatibility, strong pumpability, improved final finish, improved impact resistance and enhanced frost resistance.
Fly ash instead of clay raw materials for the production of cement, not only to reduce costs, but also to improve the ease of concrete, improve the impermeability, gas, sulfate resistance and resistance to chemical erosion, reduce the heat of hydration, improve the high temperature resistance of concrete, reduce particle separation and precipitation of water phenomenon, reduce the shrinkage of concrete and cracking as well as inhibit the corrosion of stray currents on the steel reinforcement in concrete.
Steamed fly ash bricks, with high heat preservation efficiency, refractoriness, small thermal conductivity, can reduce the thickness of the furnace wall, shorten the firing time, reduce fuel consumption, improve thermal efficiency, reduce costs.
Fly ash has good physicochemical properties, can be widely used in the transformation of heavy clay, raw soil, acidic soil and saline soil, to make up for the defects of its acid thin board sticky, fly ash contains a large number of water-soluble silica, calcium, magnesium, phosphorus and other nutrients necessary for crops, so it can be used as agricultural fertilizer.
The specific application of fly ash here no longer a detailed description, for more information about the application of fly ash can consult the website customer service, 24 hours online, for your service.
