Abstract: Optical spectroscopy is a viable approach for subsurface monitoring of pH levels in civil engineering materials. In this work, we describe a method by which optical fibers may be implemented as probes for the in situ ...

Abstract: This paper presents the results of a study on the effect of high temperatures on the mechanical properties of high-strength concretes. Mixtures were prepared with water to cementitious material ratios of 0.40, 0.35, and ...

Abstract: Understanding the behavior of steel-concrete interaction is of fundamental importance to the study of reinforced concrete structures. In this paper, a technique for the development of a constitutive model for that interaction ...

Abstract: This paper demonstrates the usefulness of near-infrared optical fiber analysis for sensing moisture and liquid hydrocarbons in soil. Through experiments we have carried out sensing probes which have been developed, comprising ...

Abstract: Phase-change materials (PCMs) have a high heat of fusion compared to that of traditional material, and for this reason, they are able to store and release larger amounts of energy at their transition temperature. The ...
