摘要

地聚合物混凝土是一种复合材料，具有替代传统混凝土的潜力。本文对整体式地聚合物混凝土界面抗剪强度进行了试验研究。共铸造和测试了18个跨界面加筋和不加筋的推脱试件。将地聚合物混凝土的试验抗剪强度与现有的普通混凝土抗剪强度分析模型进行了比较。试验结果表明，整体式地聚合物混凝土界面抗剪强度提高，达到一定的地聚合物混凝土抗压强度。现有的分析模型在估计地聚合物混凝土抗剪强度时大多是保守的。

A comparative study of shear strength of monolithic geopolymer concrete interface

Geopolymer concrete is the composite and has prospective potential to become one of the alternatives to conventional concrete. This paper presents an experimental investigation on the shear strength of monolithic geopolymer concrete interface. A total of 18 push-off specimens with and without reinforcement across the interface were cast and tested. The experimental shear strength of geopolymer concrete is compared with the shear strength evaluated, using the available analytical models for normal concrete. The test results indicated that the shear strength of monolithic geopolymer concrete interface has increased up to certain compression strength of geopolymer concrete. Most of the available analytical models are conservative in estimating the shear strength of geopolymer concrete.
