Abstract

Microwave materials characterization techniques have been extensively and successfully used for evaluating important properties of a wide range of cement-based materials and structures. Recent investigations using these techniques for studying properties of mortar with alkali-silica reaction (ASR) gel have also been very promising. In this research, microwave dielectric properties of multiple mortar samples with different compositions and when subjected to different humidity levels are investigated. This paper presents the results of these experiments and the subsequent analysis pertinent to humidity-related issues in the mortar samples.
