Product Application
Silica fume,GGBS,Pulverized Fuel Ash.




1.Microsilica powder has the characteristics of high amorphous SiO₂ content, low impurity components, high chemical activity, fine particles, large specific surface area, etc., and it has a wide range of applications, which mainly include the following fields:
Construction field: used in high-performance concrete, which can significantly improve the performance of compression, flexural, seepage, etc., and prolong the service life of the concrete, and it is commonly used in high-rise buildings, harbour terminals, It can be used in high-rise buildings, harbour terminals, reservoirs and dams, etc. It can also be used in mortar, such as dry mortar, repair mortar, heat preservation mortar, etc. It can improve the performance of mortar, and enhance its adhesion, crack resistance and durability.
Refractory material field: it is an important additive for high-grade and high-performance low cement refractory castables and prefabricated parts, which can improve the refractoriness, high-temperature strength and thermal shock resistance, and prolong the service life, and it can also be used in the field of high temperature ceramics, such as large-scale iron gully and ladle materials, permeable bricks, coated patches and so on, as well as oxides-bonded silicon carbide products, high-temperature abrasion-resistant materials and other high-temperature ceramics.
Chemical field: it can be used as the reinforcing material of organic compounds, used in rubber, resin, coating, paint, unsaturated polyester and other polymer materials, which can improve the comprehensive performance of the material such as strength, toughness, abrasion resistance, etc. It can also be used as the anti-caking agent in the fertiliser industry to prevent the caking of fertiliser.
Other fields: it can be used in the production of chemical products such as water glass; as an adsorbent for wastewater treatment, removing heavy metal ions and organic pollutants in water; it can also be used as a soil conditioner, improving the soil structure, increasing the fertility and water retention capacity of the soil.
2.Fly ash has a wide range of applications, mainly including the following aspects:
Concrete admixture: can improve workability, improve compactness and durability, reduce cracking, but also reduce the amount of cement and the heat of hydration, used in the preparation of pumping, bulk and other types of concrete.
Production of building products: it can be used for autoclaved fly ash bricks, sintered fly ash bricks, autoclaved foam fly ash heat preservation bricks, fly ash silicate blocks, fly ash aerated concrete, fly ash ceramic granules and so on.
Road engineering: it can be used as road base or sub-base material, mixed with gravel to produce road surfacing material, and also can be used as additive for road repair material to improve the service life of road.
Production Equipment
The production process of silica powder includes raw material preparation, furnace preparation, calcination, crushing, classification, auxiliary treatment, packaging and storage. Among them, calcination and crushing are the key steps, which have an important impact on the quality and performance of the final product. Warrenty Building Materials factory has crushing equipment, grinding equipment, grading equipment, auxiliary treatment equipment, packaging equipment, dust removal equipment and conveying equipment. During the production process of silica powder, we strictly control every step to ensure the quality and stability of the product.
Our advantages
Production Market
Warrenty's sales of silicon powder and mineral powder products cover the whole country and are exported to Hong Kong, Macao, Japan, the Middle East, Southeast Asia and Europe.
After signing the silica fume supply contract with Hong Kong Alliance Building Materials, Warrenty Building Materials Limited, provide one-stop after-sales service such as supply of silica fume materials for Hong Kong Alliance Building Materials, which is deeply loved, so far, the co-operation and co-construction of the performance demonstrated.
Our Service
Our products are supported by highly qualified staff who provide customer service, technical support and product development advice. For example, many of our customers work closely with Warrenty to test products to different specifications at upstream customers, and Warrenty also provides samples and small batches to ensure that these products are perfectly tuned prior to high-volume production.
Once a customised product meets specifications, Warrenty silica powders are packaged in standard 25kg bags or 1000kg sacks, and bulk tanker trucking is available for customers in Hong Kong and Macau.
