Cement-based Crystallizing Water-proof Material - MUHU ...

These needle-like crystals grow until all pores are blocked and no water can penetrate the concrete. The crystalline formula can allow concrete to self-seal hairline cracks up to 0.5 mm (0.02 in.), even years after the original construction. Concrete treated with these admixtures contains chemicals that lie dormant within.

Alkali-silica reaction in concrete - Understanding Cement

ASR is caused by a reaction between the hydroxyl ions in the alkaline cement pore solution in the concrete and reactive forms of silica in the aggregate (eg: chert, quartzite, opal, strained quartz crystals). A gel is produced, which increases in volume by taking up water and so exerts an expansive pressure, resulting in failure of the concrete.

Efflorescence (White Crystal Deposits) - Sherwin-Williams

Efflorescence is often seen as a white fluffy deposit of salt crystals on cementitious (e.g. masonry) wall surfaces. Efflorescence depends on the presence of salt and moisture, and the growth of crystals will continue as long as both are present. The salts are present in the mortar, blocks, or concrete structure, and the moisture is usually ...
