85% 濃度のマイクロシリカ (シリカフューム) 85d

85% 高密度のシリカフューム (85d) is a type of silica fume that has been processed to increase its bulk density. This makes it easier to handle and transport, and can also improve its performance in concrete.

85% 高密度のシリカフューム, is a byproduct of the production of silicon and ferrosilicon alloys. It is a highly reactive pozzolan with a high silica content of over 85% and a bulk density of around 550-700 kg/m3. The specific surface area of 85% Densified Silica Fume is very high, ranging from 15,000 to 30,000 m2/kg, making it an ideal supplementary cementitious material for enhancing the strength, 耐久性, and workability of concrete.

The cost of the silica fume is influenced by multiple factors, such as SiO2 content, logistics transportation cost, labor cost, ect. 一般的に, the price of silica fume ranges from $150 to $800 per metric ton. しかし, prices can sometimes exceed this range for high-quality, specialized products or for small orders.Due to different needs, which means that the price is changed, so we are unable to provide online quotes. We will send you the detailed quotation after you send us your requirements.

Silica fume and fly ash are both supplementary cementitious materials that can improve the performance of concrete. Silica fume is composed of extremely fine particles of amorphous silica, while fly ash is a byproduct of coal combustion and composed of small spherical particles of inorganic material. Silica fume particles are much smaller than fly ash particles, and it is generally considered to be a more reactive pozzolan than fly ash. Silica fume is known for improving the compressive strength of concrete at early ages, while fly ash is typically used to improve the long-term strength and durability of concrete. The choice of which material to use will depend on the specific application and performance requirements of the concrete being used.
