聚合物混凝土具有較傳統混凝土更高的抗壓強度，且早期強度發展快速、有更佳的耐化學腐蝕性及更佳的耐久性等優點。若以此為建材，可延長建築物壽命，進而能減少資源浪費及達到節能減碳之目的。而未來若能進一步使用於地下水庫或隧道，勢必面臨到液體與聚合物混凝土兩者間力學相關破壞機制，故本研究以聚合物水泥砂漿為材料，並與傳統水泥砂漿比較，藉由施做液驅破壞同步聲射定位技術之試驗，探討材料受液體壓力驅破之完整加載歷程及裂縫衍生之過程，以及巨觀、微觀之力學行為。傳統水泥砂漿之峰後可控制之時間會隨著試體強度提高而縮短，而聚合物水泥砂漿之強度會隨著養護時間增長而增加，且齡期一天及三天之試體受液驅破壞之行為亦不相同，分別為產生裂隙及完全開裂，而此現象與其膠結材固化程度有關。齡期一天之試體會因水壓洩出而試體回彈，齡期三天之試體則因完全開裂而無法得知其峰後資訊。

Polymer concrete has higher compressive strength than traditional concrete, and has the advantages of rapid development of early strength, better chemical resistance and better durability. If this is used as a building material in the future, due to its own strength and durability against harsh environments, the life of the building can be extended, and resource waste and energy saving and carbon reduction can be reduced. In the future, if it can be further used in underground water reservoirs or tunnels, it is bound to face the mechanically related failure mechanism between liquid and polymer concrete. Therefore, this study uses polymer cement mortar as the material and compares it with traditional cement mortar. Through the experiment of fluid-driven fracturing apparatus with coupling acoustic emission, the complete loading history of the material driven by liquid pressure and the process of crack derivation, as well as the macroscopic and microscopic mechanical behavior are discussed.
The time that can be controlled after the peak of the traditional cement mortar will decrease as the strength of the specimen increases, while the strength of the polymer cement mortar will increase as the curing time increases. Moreover, the behaviors of the one-day and three-day specimens damaged by fluid-driven are also different, which are cracks and complete cracking, respectively, and this phenomenon is related to the degree of solidification of the cement material. The one-day curing body will rebound due to water pressure leaking, and the three-day specimen will be completely cracked without knowing its post-peak information.
