| Abstract | All efforts are being made to tailor the properties of concrete by replacing binder and filler with appropriate materials based on the environmental conditions. Many prospective players came into vogue for the purpose. Expanded clay showed promise for use in structural lightweight concrete. The addition of discontinuous discrete fibres proved to be beneficial in further improving the performance of structural lightweight concrete. A comprehensive laboratory investigation has been carried out to assess the influence of polypropylene fibres on the properties of expanded clay-based structural lightweight concrete. Expanded clay aggregates (ECA) have been used in varying percentages of 10%, 20%, 30%, 40% to replace coarse aggregates. Polypropylene fibres have been used in volume fractions of 0.1%, 0.2%, 0.3% and 0,4%. Based on trials, the optimum dosage of expanded clay aggregates for meeting the workability and strength requirements has been obtained. The laboratory results showed that the inclusion of polypropylene fibres improved the properties of structural lightweight concrete appreciably. |
