Limited information is available on ettringite formation in sulphate enriched marine clays (Rajasekaran, 1994, Rajasekaran et al., 1997). Hence, studies on ettringite should be critically investigated for the successful application of deep cement and lime mixing techniques in marine clays (Rajasekaran, 1994).

Ettringite was synthesised in an anoxic glove box under a nitrogen (N₂) atmosphere following the method reported by Perkins and Palmer [26]. The synthesis involved mixing 0.02 M Al 2 (SO 4) 3 ·18·H 2 O and 0.12 M Ca(OH) 2 in 1 L of ultrapure water, which had been previously boiled and N₂-sparged to minimise CO 2 …

A comparison of the results, indicated in Table 2 and previous works, shows that as the time required for ettringite formation increases the value of P decreases. It should be noted that by rearranging Eq. (4) to fit the form of Eq. (1), the coefficient of N will be 1/0.63 or 1.59 and coefficient of P will be 0.00033, which are in the same order of …

The use of ettringite-based materials for thermochemical heat energy storage has attracted researchers' attention in recent years since ettringite has advantages like low material cost and high energy storage density (~500 kWh/m 3).However, carbonation, which modifies its structure and reduces the capacity of energy storage, is …

Ettringite-based thermochemical energy storage has been recommended to be used in buildings for thermal energy supply because of its low material cost (<1000 €/m 3), low working temperature and high energy storage capacity.However, several physicochemical properties of ettringite were still not clear, such as reversible reaction …
