Abstract

In this study electrically characterizing the changes in wood (organic) and smart cement (inorganic) due to moisture changes was investigated using 2-probe method. Also, Ultrasonic Pulse Velocity was used to investigate the changes in the compressive wave speed with changes in moisture content. Smart cement was modified by adding UH-biosurfactant and characterized the changes in the initial resistivity, curing characteristics and the piezoresistive behavior. Also, smart cement was exposed to different water levels (external) and changes in the resistivity were correlated with moisture content. The experimental results were correlated with Vicat Appartus tests and were modeled using Vipulanandan models and Artificial Neural Network (ANN) models. Wood, one of the most commonly used natural materials was studied for variable moisture saturation conditions and electrical measurements were then recorded to monitor and characterize the changes. Also, Ultrasonic Pulse Velocity test, one of the most established and widely used non-destructive test (NDT) was used to correlate with the moisture changes and resistivity in the wood.
