Colloid transport in a glacial sand aquifer. Laboratory and field

Based on calculated sticking efficiencies of the DNA-tagged silica tracer to the sand grains, we concluded that a large fraction of the DNA-tagged silica tracer colliding with the sand grain surface did also stick to that surface, when the ionic strength of the system was higher. The experimental results revealed the sensitivity of DNA-tagged ...

silica, compound of the two most abundant elements in Earth 's crust, silicon and oxygen, SiO 2. The mass of Earth's crust is 59 percent silica, the main constituent of more than 95 percent of the known rocks. Silica has three main crystalline varieties: quartz (by far the most abundant), tridymite, and cristobalite.

Polymeric Sand vs. Silica Sand: Which to Choose?

Silica sand consists mainly of silica, whereas polymeric sand only has a small amount of silica used as an additive. 3. They're Both Very Fine. Another similarity shared by both polymeric sand and silica sand is that they are both extremely fine. To the touch, they feel more like a fine powder than anything else.

Material Safety Data Sheet

*Crystalline silica is normally measured as respirable dust. The MSHA standard also presents a formula for calculation of the OEL based on total dust: 30 mg/m3 / (% SiO 2 +2). ** The ACGIH and NIOSH limits are for crystalline silica (quartz), independent of % silica content of the respirable dust sample.

synthesis

I found one reference instructing to wash 30 g of sand twice with 0.05 M sulfuric acid, then four times with distilled water. However, other references instructing to use only hydrochloric acid and de-ionized water, but have not specified how much or the concentration. Yet another reference says that sulfuric, hydrochloric or phosphoric acid ...

Silica Sand

To make calcium silicate bricks, silica sand is mixed with high calcium lime at a sand–lime ratio of 10 or 20. The mix is then compressed into moulds and "autoclaved" at about 170°C (340°F) for several hours. Some gel, similar to the calcium silicate hydrate gel of the type that is formed by cement, is formed, and this bonds the sand particles together.
