Civil structures are important to society. For durable and safe service lives, good design, quality construction as well as appropriate management during service are important goals of structural engineering management and monitoring are often essential parts of managing activities. Therefore, monitoring structures from construction to the end of the service may be useful for concrete structures; this includes monitoring during the early age. In this paper we had develop a structural health monitoring using fiber optic sensor and strength of concrete improved by E-Waste. For many point view, fiber optic sensors are the ideal transducers for civil structural monitoring. Being durable, stable from the incentive to external perturbations. They are particularly interesting for the long term health. Now a day’s in India the construction is slowed down due to the increase in demand and unavailability of construction materials at feasible cost. Using alternative materials will overcome this problems an effort have been made in the construction industry to use non-bio degradable components of E-waste as a partial replacement for the coarse aggregate. And manufactured sand as a fine aggregate. It is purpose made fine aggregate produced by crushing and screening or further processing i.e. washing, grading, classifying of quarried rock, cobbles, boulders or gravels from which natural fine aggregate had been removed. An experimental study is made on the utilization of E-waste particles as coarse aggregate in concrete with a percentage replacement ranging from 0% to30% with the strength criteria of M40 concrete. Compressive strength, tensile strength, flexural strength of concrete with and without concrete as a coarse aggregate and the stress and strain induced in the structural member by using optical fiber sensor was observed. Ultrasonic tests on strength properties were executed and the feasibility of utilizing E-plastic particles with partial replacement of coarse aggregate and fiber optic sensor for structural health monitoring has been presented.
