通过对硅铝质胶凝材料+水泥体系的水化产物和微观结构特征分析,研究多元体系叠加与互补效应对高性能复合材料工作性能及耐久性能的影响。结果表明:矿渣在水化释放OH-过程及粉煤灰水化消耗OH-过程有效加速了整体的早期水化进程,从而消除潜在不稳因素使其后期性能保持稳定。多元体系协同效应能够在工业废弃物大掺量前提下促进其水泥制品的耐久性能的有效改进。
Based on the analysis of the hydration products and microstructure characteristics of the silica-alumina cementitious material + cement system, the effects of the superposition and the complementary effects of the multi-system on the workability and durability of the high-performance composite material were studied. The results show that the process of OH- release from slag by hydration and the OH- consumption by hydration of fly ash effectively accelerate the overall early hydration process and thus eliminate the potential instability to stabilize the latter performance. The synergistic effect of multiple systems can promote the effective improvement of the durability of cement products under the premise of high volume of industrial waste.
