sedimentary stone. Calcium Silicate Masonry Units are manufactured by mixing lime with an inherently strong, silica-based sand, and pressing under high pressure. The 'green' units are then subjected to high-pressure steam in an autoclave to produce a unit with a uniformly fine-grained texture. A calcium silicate hydrate binder is formed

The cause of a popout due to a chemical reaction is often related to alkali-silica reaction (ASR). Alkalis from cement or other source cause an environment of high pH (high concentrations of OH ions) causing the breakdown of silica and formation of an ASR gel, which absorbs water and expands, removing a small portion of the surface mortar with it.
