Abstract
The present research focuses on durability aspects of limestone calcined clay cement (LC3) using different piezo configurations specifically aimed at acid attack. The experimental study was carried out on concrete cylindrical specimens of ordinary Portland cement (OPC) and LC3, which were immersed into the sulphuric acid (H2SO4) and hydrochloric acid (HCl) solution. Different piezo configurations were installed to acquire the data in the form of conductance and susceptance signatures via electro-mechanical impedance (EMI) technique. From the acquired data, the equivalent structural mass parameter was extracted which was then validated with actual mass obtained by physical measurement. Based on the results, it can be concluded that the equivalent mass parameter is able to identify the mass loss in the specimens subjected to acidic environment non-destructively.
