“…They found that the addition of PA and phase-5 seed crystals reduced the porosity The researchers have utilized a variety of SCMs to address this issue, including FA, silica fume, GGBFS, MK, alumina, nano silica, glass powder, sludge ash, and pulverized fuel ash, as well as soluble phosphates including PA, potassium phosphate, MFP, etc. [8,23,83]. The main aim of adding these admixtures and modifiers was to develop stable waterresistant hydrated products.…”

Magnesium oxychloride cement (MOC), an alternative to ordinary Portland cement (OPC), has attracted increasing research interest for its excellent mechanical properties and its green and sustainable attributes. The poor water resistance of MOC limited its usage mainly to indoor applications; nevertheless, recent advances in water-resistant MOC have expanded the material’s potential applications from indoor to outdoor. This review aims to showcase recent advances in MOC, including water-resistant MOC and ductile fiber-reinforced MOC (FRMOC), exploring their potential applications including in sustainable construction for future generations. The mechanism under different curing procedures such as normal and CO2 curing and the effect of different inorganic and organic additives on the water resistance of MOC composites are discussed. In particular, the review highlights the recent developments in achieving over 100% strength retention under water at 28 days as well as advancements in FRMOC, where tensile strength has surpassed 10 MPa with a remarkable strain capacity ranging from 4–8%. This paper also sheds light on the potential applications of MOC as a fire-resistant coating material, green-wood-MOC composite building material, and in reducing solid waste industrial byproduct accumulations. Finally, this study suggests future research directions to enhance the practical application of MOC.

“…Magnesium oxychloride cement (MOC) is a kind of MgO-MgCl 2 -H 2 O ternary composite system mixed with active MgO, MgCl 2 and H 2 O [23][24][25]. Compared to the bone cement typically utilized in clinical settings, MOC bone cement has excellent mechanical properties and is biodegradable, and the Mg 2+ produced during degradation can promote the absorption of Ca 2+ in the body, which is beneficial to bone repair [26][27][28].…”

In response to the shortcomings of magnesium oxychloride cement (MOC), which has excellent with outstanding mechanical properties and favorable bioactivity but poor water resistance, strontium hydrogen phosphate (SrHPO4) was used as a water resistance modifier for MOC in the paper, and the effects of SrHPO4 on the strength, water resistance, in vitro degradation and bioactivity of MOC were investigated; the results showed that SrHPO4 could enhance the water resistance of MOC, in which the initial strength of MOC containing 4.0 wt% SrHPO4 was 92.3 ± 2.5 MPa, and the strength was still 8.2 ± 0.9 MPa after 84 d of immersion in SBF solution; the degradation experiments of the samples in SBF solution showed that the degradation of SrHPO4-MOC was controlled, and the low alkaline environment created by the degradation promoted the deposition of hydroxyapatite on the cement surface, it indicated that SrHPO4-MOC material had good degradation properties and bioactivity; cell experiments showed that compared with MOC, SrHPO4-MOC was noncytotoxic and could promote cell proliferation, which was expected to be a new material for bone repair.
