Construction workers may be exposed to hazardous dust containing silica when cutting fiber-cement siding. The National Institute for Occupational Safety and Health (NIOSH) found that workers' exposures could be reduced by attaching a regular shop vacuum to a dust-collecting circular saw providing a simple low-cost solution.
It can also be used in construction, for example in making concrete or as a bedding material for underground pipelines. Silica sand with a particle size distribution of 0.0-1000 would contain no particles smaller than 1000 microns (1 millimeter) in size. ... ceramics, and even white cement. This type of silica sand is also used as a abrasive ...
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. Silica fume is a by-product of the silicon metal/ferrosilicon alloy industry.
It causes a decrease in the cement hydrate volume and an increase in porosity and water absorption. The simultaneous increase in BSS and substitution ratio causes an increase in WA from 4.2% (M0) to 6.8% (M4-BSS3). The observed trend is attributed to the angular shape of silica sand grains, making granular stacking a bit …
The investigation employed two distinct mixing techniques, mixing cement and silica fume, before extracting appropriate samples; alternatively, a magnetic stirrer was used to prepare samples by dissolving silica fume in water. The cement mortars were also prepared with three different water–cement ratios: 0.44, 0.47, and 0.5.
CEMEX Microsilica + is a supplementary cementitious material, comprising of amorphous silica produced by electric arc furnaces as a byproduct of the production of elemental silicon or ferro silicon alloys and selected additives.
