Abstract
It is important to advance concrete technology in order to ensure that this vital material meets humanity's existing and future needs. This study, along with similar worldwide investigations, has produced experimental data which shows that traditional concrete mixes can be improved both structurally and environmentally by replacing partial quantities of normal coarse aggregate with waste products e.g., Crumbed Rubber (CR) and Crushed Glass (CG). This chapter presents details of both the mix designs investigated, and the testing results, including insights gained from the testing program. The investigation utilized sections of the most relevant methodologies for concrete technology within the Australian Standards. The mix designs and subsequent mixing and curing procedures were determined by using a Portland Cement Concrete mix (PCC) as the control, and varying the quantities of aggregates by weight. A constant water cement ratio (W/C) of 0.63 was maintained throughout the investigation. It was observed that a maximum of 25% of normal coarse aggregate could be replaced with CR and CG at ratios of 20% and 5% respectively. At the limit of the testing program the average slump value was maintained above 70mm, the density achieved was 2,320kg/m3, and a Modulus of Elasticity of approximately 15GPa, and an average compressive strength of 18Mpa, were achieved. Additionally, the flexural and indirect tensile strengths of the various mixes were tested and found to be acceptable for non-structural purposes. The findings can be considered as pioneering work for future developments in the field of concrete technology and for creating possible future mix designs. By bridging the gap in the body of knowledge relating to glass and rubberized concrete mix designs this investigation produced some surprising and informative results. It also provides researchers with additional information examining important implications involving the replacement of up to a quarter of the total coarse aggregate volume with smart, environmentally friendly materials.
