This paper analysis the new important advancement in the area of greatly sensitive strain sensors made from CNT and concentrates the piezoresistive property of the CNT/concrete composite to investigate its feasibleness as an inserted stress sensor for common structures, for example, roads, buildings and bridges. The piezoresistive effect for any material is a change in the electrical resistivity of that material when mechanical strain is given. The mechanical/electrical and piezoresistance properties of multi walled nanotubes are studied in deep. This paper surveys the ongoing significant advancements in the area of profoundly delicate strain detectors produced using CNT/polymer nanocomposites. Great concern has produced in constructing exceptionally sensitive strain detectors with these unique nanocomposites.The piezoresistive reactions of the composite with various CNT
