Opis

After this first set of elastic experiments, the same specimens were gradually loaded in UTM until material's failure to determine damage sensing ability of the self-sensing concrete. All specimens with fibers showed initially decreasing resistance upon compression, but on increasing the compressive load the resistance also increased. The increase in resistance was gradual upto 75% of the fracture stress, but it was abrupt and quite linear for stresses beyond this range (i.e., above 75% of fracture stress). Thus, among the concrete mixes containing variable percentages of carbon fibres, the ones having fibre percentage greater than 1.5 were most attractive, as they exhibited a combination of linearity (between resistivity and stress) and large fractional resistivity increase.
