Composite sleeper is becoming a suitable alternative for replacing the existing concrete, steel and particularly timber sleeper in both mainline and heavy haul rail network. Composite sleeper technologies are already available in the last 20 years but they have gained limited acceptance by the railway industry. For better understanding of the reasons for their slow uptake in the market, a comparative study was conducted among the existing composite sleepers. Firstly, this paper accumulated information on the performance of commercially available composite sleepers. Secondly, issues on the application and developments of composite sleepers are identified. Thirdly, the ongoing research on the …

The limited research on the geopolymer concrete mix design for targeting a specific strength is identified an obstacle for their effective design and wide use. In this paper, a mix design procedure has been proposed for fly-ash based geopolymer concrete and its use as infill hybrid composite beam is investigated. Then, the structural performance of geopolymer concrete filled hybrid composite beam is investigated to determine their possible application in civil infrastructure. Firstly, a detailed procedure of mix design for fly-ash based geopolymer concrete is presented. Secondly, three hybrid beams filled with geopolymer concrete were prepared and tested in a four-point …
