  • Scawtite - Wikipedia

    en.wikipedia.org/wiki/Scawtite Scawtite is a hydrous calcium silicate mineral with carbonate, formula: Ca 7 (Si 3 O 9) 2 CO 3 ·2H 2 O. It crystallizes in the monoclinic crystal system as thin plates or flat prisms.. Scawtite was first described in 1929 for an occurrence at Scawt Hill in Northern Ireland.. Scawtite occurs as in skarns and hydrothermal veins in limestone.Associated minerals include melilite, spurrite ...

    www.sciencedirect.com/science/article/pii/S0016703713001877 Scawtite is hydrated but spurrite is not, so the former will be favored by high water activity. Since spurrite is more calcium rich than scawtite, spurrite formation will be thermodynamically favored over that of scawtite by high calcium activity in aqueous solution or higher Ca/Si ratios in the surrounding rocks, as well as by lower H 2 O activity

    www.onepetro.org/doi/10.2118/9286-PA Scawtite appears to be an inferior phase by itself, but in small quantities it can be helpful in strength development. Introduction. The failure of wells in several geothermal fields has been directly attributed to degradation of cement. This implies that the cementing materials used to complete geothermal wells had not been sufficiently evaluated.

    www.sciencedirect.com/science/article/pii/0008884684900139 The instability of scawtite under the C02 excess (C02/C7S6 > 1) is influenced by its structural arrangement. The present channels enable penetration of C02 molecules into the structure and formation of carbonated phases. Introduction Scawtite, 7Ca0.6Si02.C02.2H20, is the only known quarternary phase in the system Ca0-Si02-CO -H20.
