2018-3-5 · Ettringite is a hydrated calcium sulphoaluminate that contains a high amount of water (45 wt%) and has a structure corresponding to Cae[Al(OHe]2(S04)s.25 H 2 0 (23). About twenty four of water molecules that are weakly bounded (interstitial position) are lost at 100-110°C with shrinkage of lattice.

2021-2-12 · Ettringite is an especially crystalline compound with a high aspect ratio that can form long needle like crystals. Once nucleation has occurred, ettringite crystals tend to grow lengthwise. Even when the tips of the crystals encounter solid material the growth continues resulting in very high localized stresses that lead to expansion and ...

2020-7-19 · This ettringite is often called primary ettringite. If concrete is exposed to moisture for long periods of time (many years), the ettringite can slowly dissolve and reform in less confined locations. Upon microscopic examination, harmless white needle-like crystals of ettringite can be observed lining air voids.
