MOC samples incorporating different admixtures are prepared, and their hydration products and microstructures are studied via X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results indicate that the addition of H3PO4, KH2PO4 and NaH2PO4 reduces the initial and final setting times and decreases the compressive strength. However, the compressive strength of MOC is higher than 30.00 MPa with the addition of 2.0 wt.% phosphoric acid and its phosphate after 14 days of air curing. The water resistance of modified MOC slurries is significantly improved. The softening coefficient of MOC with 2.0 wt.% H3PO4 is 1.2 after 14 days of water immersion, which is 3.44 times higher than that of the neat MOC. The enhancement in water resistance is attributed to the formation of amorphous gel facilitated by H3PO4, KH2PO4 and NaH2PO4. Furthermore, the improvement in water resistance is manifested as H3PO4 &gt; KH2PO4 &gt; NaH2PO4.<\/jats:p>","DOI":"10.3390\/ma17194828","type":"journal-article","created":{"date-parts":[[2024,9,30]],"date-time":"2024-09-30T11:32:05Z","timestamp":1727695925000},"page":"4828","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Effect of Phosphoric Acid and Soluble Phosphate on the Properties of Magnesium Oxychloride Cement"],"prefix":"10.3390","volume":"17","author":[{"given":"Qing","family":"Huang","sequence":"first","affiliation":[{"name":"School of Materials Science and Engineering, Shaanxi University of Technology, Hanzhong 723001, China"},{"name":"National and Local Joint Engineering Laboratory for Slag Comprehensive Utilization and Environmental Technology, Shaanxi University of Technology, Hanzhong 723000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Su","family":"Wang","sequence":"additional","affiliation":[{"name":"Lithium Resources and Lithium Materials Key Laboratory of Sichuan Province, Tianqi Lithium Corporation, Chengdu 610000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongsheng","family":"Du","sequence":"additional","affiliation":[{"name":"Key Laboratory of Comprehensive and Highly Efficient Utilization of Salt Lake Resources, Qinghai Institute of Salt Lakes, Chinese Academy of Sciences, Xining 810008, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhigang","family":"Yin","sequence":"additional","affiliation":[{"name":"Lithium Resources and Lithium Materials Key Laboratory of Sichuan Province, Tianqi Lithium Corporation, Chengdu 610000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bing","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Shaanxi University of Technology, Hanzhong 723001, China"},{"name":"National and Local Joint Engineering Laboratory for Slag Comprehensive Utilization and Environmental Technology, Shaanxi University of Technology, Hanzhong 723000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jie","family":"Zhang","sequence":"additional","affiliation":[{"name":"Lithium Resources and Lithium Materials Key Laboratory of Sichuan Province, Tianqi Lithium Corporation, Chengdu 610000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7541-3681","authenticated-orcid":false,"given":"Weixin","family":"Zheng","sequence":"additional","affiliation":[{"name":"Key Laboratory of Comprehensive and Highly Efficient Utilization of Salt Lake Resources, Qinghai Institute of Salt Lakes, Chinese Academy of Sciences, Xining 810008, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,30]]},"reference":[{"key":"ref_1","first-page":"102","article-title":"On a new magnesium cement","volume":"65","author":"Sorrel","year":"1867","journal-title":"Comptes Ren-Dus-Acad.
