This study compares, for the first time, MgO-based (MB) cement and Portland-based (PB) cement for stabilizing earth mortars. While MB and PB earth mortars reach similar strength, MB cement stabilization demonstrates superior early-age performance. Thermogravimetric analysis, X-ray diffraction, 29Si and 31P NMR spectroscopies show that the cement reacts in both systems and allow to establish the phase assemblages. The stabilized earth pastes contain less hydroxide phases, indicating a pozzolanic reaction in both cases.

使用 MgO 基水泥进行地球稳定



本研究首次比较了 MgO 基 (MB) 水泥和波特兰基 (PB) 水泥用于稳定土方砂浆的作用。虽然 MB 和 PB 土砂浆的强度相似,但 MB 水泥稳定剂表现出卓越的早期老化性能。热重分析、X 射线衍射、29Si 和 31P NMR 波谱表明,水泥在两个系统中发生反应,并允许建立相组合。稳定的土浆含有较少的氢氧化物相,表明在这两种情况下都是火山灰反应。
