Description
Commodity Name: Silica Fume
Use: Apply to such trade as the hydroelectric project, cement, refractory material, highway, bridge, tunnel, chemical industry, ceramics, rubber, ect.
Microsilica (silica fume) has been called the most important new product in concrete technology in the 1990's and has given civil engineers another tool in the design and construction of structures for the next century.
Bridge construction, marine structures, parking structures, water supply and sewage facilities all benefit from the use of microsilica (silica fume). The special properties of microsilica concrete give benefits in fresh concrete properties, so rheology improvements give benefits for concrete pumping and stability of the concrete mix. Special concretes like high strength concrete, light weight concrete (LWC, LWAC), shotcrete and low permeability concretes are better made with microsilica
Silica fume (microsilica) is usually added as an additional (supplementary) cementitious material at a (dry) percentage of the original cement content. In most cases the amount of microsilica can be added to the cement for the purpose of calculating the water –binder ratio, although a correction factor is sometimes applied for this purpose, reference should be made to the appropriate national or international standard for silica fume.
