  • Silica Sand

    To make calcium silie 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 silie hydrate gel of the type that is formed by cement, is formed, and this bonds the sand particles together.

  • From sand to flat glass

    The use of recycled glass ( cullet) as an alternative to sand as a source of silicon dioxide (SiO 2) has proved to be an efficient way to reduce CO 2 emissions from flat glass manufacturing and sand consumption; one tonne of recycled glass replaces tonnes of sand. Over the last decades, the European flat glass sector has increased the share of cullet in its batch ...
