Thermal physical and mechanical properties of raw sands ...

2017-11-21 · The mechanical properties of sand cores were investigated with a special focus on the de-coring ability of sand cores. Five different sand cores composed of the same silica sand but with different binders and process parameters were tested. Silica sand cores were found to be consistent with the observation using SEM.

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.
