Abstract Alkali-activated dolomite (AD) was successfully prepared from dolomite powder by alkali activation via the process of compression molding at room temperature (22 °C). The AD put up excellent early strength and high strength properties: the 2-day and 28-day compressive strength of AD reached 58 MPa and 122 MPa respectively. Based on the corresponding characterization analysis, such as XRD, SEM, EDS, the polymerization mechanism of AD polymer was discussed. The consolidation process of dolomite powder was considered to involve two kinds of chemical reactions that were dolomitization and ion cross-linking.

碱活化白云石及其优异的机械强度

摘要 以白云石粉体为原料，通过常温（22 ℃）压缩成型工艺，成功制备碱活化白云石（AD）。AD具有优异的早期强度和高强度性能：AD的2天和28天抗压强度分别达到58 MPa和122 MPa。基于相应的表征分析，如XRD、SEM、EDS，讨论了AD聚合物的聚合机理。白云石粉体的固结过程被认为涉及白云石化和离子交联两种化学反应。
