Abstract Here, we report the processing optimisation of two laboratory-prepared alite-belite-ye'elimite ecocements (standard and doped) that release to the atmosphere ~13% less CO2 than Portland Cement during fabrication. The processing was optimised through rheological measurements, where homogeneous pastes and mortars were finally prepared through the study and optimisation of both the superplasticiser content and the water-to-cement ratio. Both parameters were correlated with the phase assembly of selected pastes and compressive strength of the corresponding mortars. After optimisation, mortars with high compressive strengths (~72 and ~77 MPa for the standard mortar, and ~41 and ~75 MPa for the doped one, at 7 and 28 days, respectively) were prepared. Furthermore, the important increase in compressive strength from 7 to 28 days of the optimised mortar prepared from the doped ecocement is due to its composition (the higher content of belite jointly with the reaction of its active polymorph (α'H-belite)).

标准和掺杂的 alite-belite-ye'elimite 生态水泥浆糊和砂浆的加工和表征

摘要 在这里，我们报告了两种实验室制备的 alite-belite-ye'elimite 生态水泥（标准和掺杂）的工艺优化，它们在制造过程中释放到大气中的二氧化碳比硅酸盐水泥少约 13%。通过流变学测量优化了加工过程，最终通过研究和优化减水剂含量和水灰比来制备均匀的糊状物和砂浆。这两个参数都与所选糊剂的相组合和相应砂浆的抗压强度相关。优化后，制备了具有高抗压强度的砂浆（标准砂浆为~72 MPa 和~77 MPa，掺杂砂浆分别为~41 和~75 MPa，分别在7 天和28 天）。此外，
