Introduction In the ever-evolving world of construction, marine concrete structures face unique challenges due to the harsh and corrosive environment they operate in. Seawater, salt spray, and constant exposure to moisture can wreak havoc on traditional concrete, leading to premature degradation and costly maintenance. At HSA, we understand these challenges and have developed a pioneering […]

Microsilica and silicon metal powder are two very different products, in the actual use of the process, these two products are often confused, because they are inextricably linked. Microsilica We usually say that Microsilica, also known as silica fume, microsilica powder, is in the production of silicon metal or ferroalloys in the process of recycling

Silica fume, or microsilica, presents an important by-product produced during the manufacturing process of ferrosilicon and silicon metal alloys. The compound finds wide uses in concrete and provides important benefits for the marine, building construction, and oil and gas industries around the world. At HSA, the leading provider of silica fume in China, we know

Composition Condensed silica fume consists primarily of pure silica in non-crystalline form and contains more than 90% silicon dioxide. Small amounts of magnesium, iron, and alkali oxides are also present. Most particles are smaller than 1 mm with an average diameter of 0.1 mm. ASTM C 1240 limits the percent retained on the 45-mm sieve

Since microsilica particles are only about 1 / 100 the size of cement grains, the material may be hard to batch and ship. These handling problems may be overcome by mixing microsilica with water (and sometimes other admixtures) in a slurry which replaces part of the normal concrete mixing water. Densification and pelletization have also

Properties: Silica fume is an ultrafine material with spherical particles less than 1 μm in diameter, the average being about 0.15 μm. This makes it approximately 100 times smaller than the average cement particle. The bulk density of silica fume depends on the degree of densification in the silo and varies from 130 (undensified) to
