Abstract:The aim of this paper is to examine the feasibility of using recycled tires steel fibres (RTSF) in recycled aggregate concrete (RAC) for structural applications. The utilization of recycled materials in concrete can potentially conserve the environment by eliminating unnecessary consumption of limited landfill areas and reduce energy consumption. The use of recycled aggregate (RA) from construction and demolition waste and the use of RTSF derived from post consumed tires are good examples. However, the variability in the characteristics of
RA and RAC are the main engineering concerns which hinder the use of RAC in structural application. This paper examines the effect of the addition of RTSF and RA on the behaviour
of concrete. The results show that RTSF significantly improve the mechanical properties of RAC. The flexural performance of RAC with 2% (by mass) RTSF is better than normal concrete without fibres and equivalent to normal concrete with 2% fibres.
