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 …

High maintenance cost, huge carbon-dioxide emission from cement and steel industries and early failures of the traditional timber, concrete and steel sleepers motivated the composite sleepers as an alternative to replace those in the existing rail track. This poster presented the optimised composite railway sleeper concept and their static performance in laboratory scale. Results found that the optimised shape can reduce two-third volume of materials from the traditional rectangular shape and their behaviour is comparable with timber sleeper.
