摘要

掌握無機聚合物與其他材料界面黏結特性為其推廣與應用的重要課題。本研究設計一系列含不同夾層傾角試體進行單軸壓縮試驗，透過實驗途徑探討無機聚合物與水泥砂漿界面的黏結特性。實驗結果顯示：無機聚合物與水泥砂漿黏結界面的視摩擦角接近無機聚合物自身的視摩擦角，且高出水泥砂漿的視摩擦角甚多；界面的視凝聚力則分別為兩側無機聚合物與水泥砂漿基材的32-43％。本研究基於實驗結果提出一考慮基材力學特性與黏結界面強度的破壞包絡線，可供判斷不同應力狀態下無機聚合物與水泥砂漿黏結結構破壞的主控因素。

A good understanding of adhesive characteristics of interfaces between geopolymer and neighboring materials is very important in promoting the usage of these industrial materials. This study investigated the adhesive characteristics by conducting a series of laboratory uniaxial compressive tests on rectangular cement mortar specimen containing geopolymer interlayers of varying dip angles. Experimental results showed that the apparent friction angle of the interface between these two materials is comparable to that of geopolymer, and is much greater than that of cement mortar. The apparent adhesion of the interface is approximately 32-43% of that of the geopolymer and that of the cement mortar. This study proposes a failure envelope based on the strengths of geopolymer and cement mortar, and the adhesion of their interface. This failure envelope is capable of predicting the possible failure modes of the composite specimen under various stress states.
