Abstract
Civil infra-structural designs now need a new dimension, different from conventional strength and reliability approaches in that they are less energy intensive and ecologically sustainable. This brought in the use of other materials and admixtures into concrete preparation and in this study, role of flyash and nylon fibres for replacing cement and improving performance in terms of stiffness and flexibility is shown with testing and design emphasis. Beams with normal concrete, termed as CC, with flyash termed as CCF and with flyash and nylon fibres CCFN are cast and tested for performance under service, ultimate and failure conditions and results clearly indicate improvements in rotational flexibility at ultimate and failure conditions. Compressive strength enhancements are shown in Fig.1, while load deflection characteristics of beams tested are shown in Fig.2. Using these as bases, section designs are made with less energy and more eco-friendly properties for the required ultimate or service load, resulting in 15 to 20% savings and carbon emission.
