Durability
Calcium silicate bricks have good frost resistance, but should not be exposed repeatedly to either strong salt solutions, acids or industrial effluent containing magnesium or ammonium sulfates. The bricks have a negligible salt content and therefore efflorescence, and sulfate attack on the mortar, cannot arise from within the bricks. The bricks are themselves resistant to sulfate attack and can therefore be used below ground with a suitable sulfate-resisting cement mortar. However, calcium silicate bricks should not be used as pavers where winter salting can be expected.
