Abstract

Abstract Buildings subjected to elevated temperatures or thermal shock can be exposed to many changes in their properties, such as phase transformation and weight loss; therefore, the thermomechanical stability of mortars is essential to maintain their properties. In this work, different ratios of partially stabilised nano-zirconium oxide (ZrO2) were used as a partial replacement by weight of kaolin to prepare a refractory mortar. Five ratios (5, 7.5, 10, 12.5, and 15%) of ZrO2, as well as unfired kaolin, water, and internal lubricant (potassium silicate) were applied to increase the specimen’s cohesion. The results showed that ZrO2 additives are suitable to be used for the production of refractory mortar as a result of increased physical and mechanical strength.

部分稳定化纳米ZrO2对粘土基耐火砂浆性能影响的实验研究

摘要受到高温或热冲击的建筑物可能会发生许多性能变化，如相变和重量损失；因此，砂浆的热机械稳定性对保持其性能至关重要。在这项工作中，使用不同比例的部分稳定的纳米氧化锆（ZrO2）作为高岭土的部分替代物来制备耐火砂浆。应用五种比例（5、7.5、10、12.5和15%）的ZrO2，以及未烧制的高岭土、水和内部润滑剂（硅酸钾）来增加试样的内聚力。结果表明，ZrO2添加剂由于提高了物理和机械强度，适合用于生产耐火砂浆。

期刊介绍： The journal focuses on the micromechanics and nanomechanics of materials, the relationship between structure and mechanical properties, material instabilities and fracture, as well as size effects and length/time scale transitions. Articles on cutting edge theory, simulations and experiments – used as tools for revealing novel material properties and designing new devices for structural, thermo-chemo-mechanical, and opto-electro-mechanical applications – are encouraged. Synthesis/processing and related traditional mechanics/materials science themes are not within the scope of JMBM. The Editorial Board also organizes topical issues on emerging areas by invitation.
