The MgO to SiO<jats:sub>2<\/jats:sub> proportion for the binder was fixed at 1:1. The nature of the hydration products were characterized using a variety of techniques including isothermal calorimetry, XRD, FTIR, and SEM. The primary binding component of the paste was determined to be magnesium silicate hydrate (M-S-H). The recovered silica exhibited faster reactivity compared to commercially available silica fume. Compressive strengths in excess of 20\u00a0MPa were obtained using the materials recovered from olivine.<\/jats:p>","DOI":"10.3389\/fbuil.2021.640243","type":"journal-article","created":{"date-parts":[[2021,5,21]],"date-time":"2021-05-21T06:34:00Z","timestamp":1621578840000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":13,"title":["Use Of Olivine For The Production Of MgO-SiO2 Binders"],"prefix":"10.3389","volume":"7","author":[{"given":"Scott","family":"Allan Nye","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shah","family":"Vineet","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Oze","family":"Christopher","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shanks","family":"Barnaby","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cheeseman","family":"Chris","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2021,5,21]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"78","DOI":"10.1016\/j.conbuildmat.2018.08.171","article-title":"Combined Impact of Silicate-Amorphicity and MgO-Reactivity on the Performance of Mg-Silicate Cement","volume":"189","author":"Abdel-Gawwad","year":"2018","journal-title":"Construction Building Mater."},{"key":"B40","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1520\/C0109","article-title":"Standard Test Method for Compressive Strength of Hydraulic Cement Mortars ( Using 2-in or 50mm Cube Specimens)","volume":"4","year":"2010","journal-title":"Am.
