废橡胶粉可持续用于碱矿渣砂浆中，节约天然骨料用量，减少环境污染。同时，具有上级变形性能的RCR能有效地抵消风荷载、地震荷载等外部动力荷载。在这项研究中，AASMs的和易性，静态和动态力学性能，和环境影响与0% - 60体积%的RCR替代细集料混合进行了研究。在-70-70 °C的温度范围下，在0.5-2 Hz的频率范围内应用动态机械分析仪（DMA）。试验结果表明，随着RCR取代率的增加，AASMs的工作性能和力学强度下降。AASM的储能模量一般随RCR的增加而降低，但当RCR取代率达到60%时，AASM的储能模量高于对照砂浆，表现出典型的热塑性材料特性。随着RCR掺量的增加，材料的损耗因子显著增加，表明RCR具有良好的耗能性能。最后，经济和生态评价表明，AASM与RCR是有益的环境。
Recycled crumb rubber (RCR) can be sustainable used in alkali activated slag mortar (AASM) to economize nature aggregate consumption and reduce environmental pollution. Meanwhile, external dynamic loads (e.g. wind load and earthquake load) can be effectively counteracted by RCR with superior deformation performance. In this study, the workability, static and dynamic mechanical properties, and environmental impact of AASMs mixed with 0% - 60 vol% of RCR substitution for fine aggregates were investigated. A dynamic mechanical analyzer (DMA) was applied in a frequency range of 0.5–2 Hz at a temperature range of -70–70 °C. The experimental results indicate that the workability and mechanical strengths of AASMs decreased with the increase of RCR replacement rate. The storage modulus of AASM generally decreases with the increase in RCR, however, once the RCR replacement rate reaches 60%, the storage modulus is higher than that of the control mortar, presenting typical behavior of thermoplastic materials. The loss factor significantly increases with the increasing content of RCR, indicating that RCR serves competently as an energy dissipating material. Finally, an economic and ecological evaluation demonstrates that AASM with RCR is beneficial to the environment.
