This paper is to investigate the effects of replacing natural coarse aggregates (NCA) with recycled concrete aggregates (RCA) and additional of steel fibres (SF) on compressive strength and flexural strength of concrete. There are four beams are provided with concrete mix design in this project by partial replacing NCA by 25% RCA and by adding 0%, 1% and 2% of SF. To determine the flexural strength, the beams of size 150mm X 250mm X 1500 mm were casted. To determine compressive strength of concrete mix, 24 cubes of size 150mm x 150mm x 150mm were prepared and tested after the period of 7 and 28 days of water curing.
