Spectral Response of Mortar Surfaces during Curing

Abstract

Imaging and non-imaging sensors that collect spectral data of surface materials are rapidly becoming available to engineers due to advances in electrooptics and sensor technology. Applications of remote sensing for the identification of surface materials and determination of some of their characteristics have been developed in the geological sciences. Transportation research systems are moving aggressively towards using these types of technologies for materials such as soil subgrades, concrete, asphalt, and, to a lesser extent, steel. A series of experiments were identified to analyze the spectral response of laboratory prepared surfaces, primarily of materials with a mineralogical origin, including soil, aggregate, and concrete. This paper presents the experimental procedure and results of a series of tests performed on a mortar mixture. Temperature, strength, and spectral reflectance were measured for a period of time during curing of the mortar. Results revealed apparent correlations between temperature, water content (curing rate), and spectral response.
