The high resistivity and low permeability of micro-silica sprayed concrete in the project can reduce the corrosion of steel bars and wire mesh by chlorides, reduce the amount of rebound, reduce permeability, and improve the durability of freezing and thawing. Improved bending and compressive strength.
Micro silica fume can be used as a binder, active agent and mineralizer for refractory materials and kiln furniture materials, which is conducive to improving the solid-phase reaction and sintering driving force of refractory materials, enhancing the reaction speed and sintering density of materials, and is conducive to crystal transformation. performance of the material.
Using silica fume as the main raw material to prepare composite silicate thermal insulation materials has gradually become a hot spot in the application of silica fume. Composite silicate thermal insulation coating is one of the most widely used thermal insulation coatings at present. It belongs to barrier type thermal insulation coating.
Silica fume can improve the performance of concrete mixture, reduce air bubbles on the surface of concrete, improve the strength of concrete surface, make the surface of concrete smooth, inhibit the carbonation of concrete, resist the erosion of harmful external media, and help improve the durability of concrete. help improve the durability of concrete.
By adding micro silica fume, optimizing concrete mix ratio, temperature control and other technical means, the PHC pipe pile can be realized without high-pressure steam curing and energy-saving technology, which not only simplifies the process, but also greatly reduces coal and electricity consumption, and also reduces carbon dioxide. emission.
Concrete mixed with silica fume is mainly used in water cushions, ponds, flood discharge tunnels and other parts. As an auxiliary cementitious material, microsilica fume can significantly improve the strength of cement stone in the concrete matrix, and at the same time greatly improve the relationship between cement stone and aggregate. between the bond strength.
Adding micro silica fume to oilfield cement can improve the thermal stability of oilfield cement, change the C/S ratio of cement, and change the composition and structure of cement hydration products. With the addition of different amounts and ambient temperatures, it can be obtained A series of hydration products with good stability, high strength and low permeability.
There is no fine sand in the permeable concrete, and the porosity is relatively large. A small change in the water-cement ratio of the blank sample can cause a large change in the fluidity of the mixture. The water-cement ratio is difficult to control, and the water-cement ratio can be significantly improved by adding silica fume. workability of fresh concrete mixtures.
Micro silica fume is used in high-grade high-performance low-cement refractory pouring materials and prefabricated parts. The service life is three times that of ordinary castables, the refractoriness is increased by about 100°C, and the high-temperature strength and thermal shock resistance are significantly improved. It has been widely used in ceramic industries.
Micro silica fume is used for agricultural fertilizer and improved soil varieties. Micro-silica fume is mixed with potassium hydroxide or potassium carbonate and heated to make potassium silicate slow agricultural fertilizer. It is not easy to volatilize and lose, can protect the soil, promote the development of crop roots, and inhibit pests and diseases.
As a manufacturer of silica fume, we offer factory direct price without trader's difference and have certain price advantage.
With an annual production capacity of 110,000 tons, we have 5 factories in china, and can arrange delivery near to customers according to their requirements to save logistics costs.
