urrently, civil infra-structural designs need a new dimension different from conventional strength and reliability approaches in
which 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 fly ash and nylon fibers 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 fly ash termed
as CCF and with fly ash and nylon fibers termed as CCFN are cast and tested for performance under service at ultimate and failure
conditions and results clearly indicate improvements in rotational flexibility at ultimate and failure conditions. Compressive strength
enhancements are shown in Figure (1), while load deflection characteristics of beams tested are shown in Figure (2). Using these as
basis, 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.
