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 …

Sand that is being transferred and loaded can release dust into the work environment. For bulk loading sand into trucks or trains, NIOSH evaluated a Dust Supression Hopper (DSH) at two industrial sand processing plants. Results show that the DSH reduced airborne respirable dust levels by 39-88%, depending on the sand size being loaded.
Heavy Equipment and Utility Vehicles Used for Grading and Excavating Tasks Using heavy equipment and utility vehicles for earthmoving tasks such as grading and excavating does not in most cases generate hazardous levels of respirable crystalline silica dust. However, in dry conditions hazardous exposures can occur.
How is crystalline silica created? Materials at risk for silica exposure include rock, concrete, brick, block and mortar. Any high-energy operation such as cutting, sawing, grinding, polishing, drilling and crushing stone can create respirable crystalline silica.
