Abstract:

This paper presents the studies on under repeated low-energy horizontal impact loading through experimental programs of Railway PSC sleepers integrated with next generation Nano based Carbon along with Fiber Reinforced Concrete. Load-time variation, displacement-time history and energy absorption capacity were studied. Carbon nano tube, Carbon fibers, Polypropylene fibers integrated with High Performance Concrete using a design mix of M60 grade of concrete. Five different PSC test specimens were casted and tested viz. M60, M60+CNT, M60+CNT+PF, M60+CNT+CF, M60+CNT+PF+CF. Carbon Nanotubes were first dispersed in deionized water and surfactant using an ultrasonic mixer, then the CNTs, Carbon fibers, Polypropylene fibers were combined with concrete as per state-of -art techniques. It can be seen that the properties of concrete matrix used in PSC railway sleepers were enhanced with respect to energy absorption capacity and peak load.
