The Silica Fume Association (SFA) was formed in 1998 to assist the producers of silica fume in promoting its usage in concrete. Silica fume, a by-product of silicon and ferro-silicon metal production, is a highly-reactive pozzolan and a key ingredient in high-performance concrete, dramatically increasing the service-life of structures.

SFA definition: Silica rök Association - Silica Fume Association

Today, very little is land filled in the USA. On August 28, 2001, the Environmental Protection Agency (EPA) published notice in the Federal Register (66 FR 45256) of its intention to add cement and concrete containing silica fume to the list of materials meeting the requirements for recycled materials under the auspices Overall, the procedures for this aspect of the work are not different from those of concrete without silica fume. The Silica Fume Association 38860 Sierra Lane, Lovettsville, VA 20180 Global Cement and Concrete Association. Silica fume. Once a nuisance waste product, silica fume is now a valuable addition to cement, creating concrete that is high strength, such as that used to build 311 South Wacker Drive, Chicago, once the world’s tallest reinforced-concrete building.

The experiments were designed using an orthogonal array technique in L16 array with four factors, namely, the water/cementitious ratio of 0.30, 0.35, 0.40 and 0.45, four different types of gradations with maximum aggregate size of 32 mm, 0, 5, 10, 15% Fly ash and 0, 10, 20 and 30% Silica fume by weight of cement. Microsilica of silica fume is een bijproduct van de productie van silicium voor onder andere geïntegreerde schakelingen.Het bestaat uit zeer kleine amorfe silica-bolletjes van gemiddeld 200 nm doorsnede, en is omwille van zijn fijnheid en hoog specifiek oppervlak (15-30 m 2 /g) een reactief puzzolaan (het neemt deel in de puzzolane reactie waarin het reageert met de calcium hydroxyde In April 2005, the American Silica Fume Association (SFA) issued a document called The Silica Fume User's Manual. This document is intended to provide practical information for individuals actually working with silica fume and silica-fume concrete. Red Industrial Products sells high quality Silica Fume in bulk for the Concrete Industry, the Oil and Gas Industry as well for the Mineral Processing Industry.
