Abstract :
Experimental work was carried out to develop information about the properties of glass aggregate concrete reinforced with chopped basalt fibre. Recycled waste mixed colour glass was used as a partial replacement (20%, 40%, and 60% by weight) for the natural fine aggregate with different volume fractions of fibre (0%, 0.1%, 0.3%, and 0.5% by total mix volume). The combined effect of the glass and the basalt fibre on the mechanical properties of the fresh and hardened concrete was investigated. The heat transfer through the thickness for this type of concrete was also investigated. A statistical analysis was also carried out to investigate the variance of the data for each mix. The test results and the statistical analysis indicated that there is a slight reduction in the compressive and splitting tensile strength with the increase in the glass content above 20%. Using basalt fibre leads to an enhancement in it for all mixes and there is an optimum content of fibre in each percentage of glass sand which gives higher strength. A slight decrease in the heat transfer through the concrete specimens was also observed.
