INTRINSICALLY SMART CONCRETE FOR STRUCTURAL HEALTH MONITORING

Abstract

Structural health monitoring and damage identification are most important to assess serviceability and safety in Civil Engineering Structures. Strain gauge or fibre-optic techniques often used for structural health monitoring but continuous monitoring and external equipment installation makes it complicated. Intrinsically Smart Concrete (ISC) is fabricated by adding functional fillers into conventional concrete which improves self-sensing ability without compromising its mechanical properties. The ISC has the potential to achieve sensing as well as a strengthening of structures along with design flexibility. There is a number of methods available to measure the resistivity but predominantly four probe method was used to measure electrical resistivity of ISC. This work is focused on the durability and strength - based quality control of concrete by considering the electrical resistivity.
