“…Within these MgO-hydromagnesite blends, the formation of an amorphous phase was observed, which could contribute to their cohesive binding [34]. A similar outcome was observed in AAS mixes, where the combined used of MgO and hydromagnesite led to improved performance via the adjustment of the pH to accelerate the dissolution of GGBS [28].…”

“…Other than nano materials, the use of hydromagnesite (4MgCO3•Mg(OH)2•4H2O) as an additive in cement-based mixes has also been investigated [23,28]. Other studies [29] looked into the influence of Mg 2+ on the kinetics of calcite precipitation and morphology.…”

“…Afterwards, the mass loss between 300 and 400 C is induced by the decomposition of hydrotalcite (Rey et al, 1992). Following the dehydration of hydrotalcite, a weak and broad peak around 600 C is generated by the decomposition of carbonates, for example, MgCO 3 , low crystalline calcium carbonate and amorphous calcium carbonate (Dung et al, 2019). The last small mass loss peak around 700 C is due to the decomposition of calcite.…”

“…Cement is a key ingredient in concrete and sandcrete production. Despite its advantageous use, the production process of cement generates a lot of CO 2 , reduction of lime stones reserves and high energy demand [7,8]. These disadvantages have led several researchers to seek out other alternatives to replace cement.…”
