The present study investigates the potential of carbonation-cured belite-rich cement (BRC) to resist magnesium sulfate (MgSO₄) and sulfuric acid (H₂SO₄) environments. BRC mortar was submerged in 5% and 10% MgSO₄ and H₂SO₄ solutions. The gains of the compressive strength and mass under MgSO₄ environment significantly depend upon the buffer (unreacted belite phase) left in the specimen after 28 days of curing. The lowest buffer level, found after 28 days of carbonation curing, stemmed from the higher reactivity of the belite phase as opposed to water curing followed by carbonation curing. Furthermore, degradations in the strength and mass were found in the H₂SO₄ environment. The presence of the calcium carbonate phase in carbonation-cured BRC mortar increased the acid resistance. An XRD analysis showed sulfate-based mineral phases in the external and core areas of a carbonation-cured BRC mortar cube, representing the higher diffusion efficiency of acid ions than magnesium ions in BRC.

本研究调查了碳化固化富伯利特水泥 (BRC) 抵抗硫酸镁 (MgSO ₄ ) 和硫酸 (H ₂ SO ₄ ) 环境的潜力。BRC 砂浆浸没在 5% 和 10% MgSO ₄和 H ₂ SO ₄溶液中。_{MgSO 4环境}下抗压强度和质量的增益明显取决于固化 28 天后试样中留下的缓冲液（未反应的贝利特相）。在碳酸化固化 28 天后发现的最低缓冲水平源于贝利特相的较高反应性，而不是水固化然后碳酸化固化。此外，在 H 中发现强度和质量的下降₂ SO ₄环境。碳化固化BRC砂浆中碳酸钙相的存在提高了耐酸性。XRD 分析表明，在碳化固化的 BRC 砂浆立方体的外部和核心区域中存在硫酸盐基矿物相，这表明 BRC 中酸离子的扩散效率高于镁离子。
