AbstractIn this study, Jordanian volcanic tuff aggregates were used as a source of construction materials in concrete mixtures. Five concrete mixtures were prepared by replacing normal aggregate with volcanic tuff aggregate of similar size in ratios of 0, 25, 50, 75 and 100%. The impacts of this replacement on concrete density, slump, bleeding, compressive strength, flexural strength, modulus of rupture, modulus of elasticity and stress-strain behavior were investigated. The results revealed an improvement in compressive strength and flexural strength at a replacement ratio of 25%, with concomitant reduction at higher replacement ratios. Modulus of elasticity, workability and unit weight decreased for all mixtures containing volcanic tuff. The impact of replacement on compressive strength was much higher than on flexural strength. Based on these results, it can be asserted that the addition of Jordanian volcanic tuff at a ratio of 25% will improve some characteristics with adverse impacts on the modulus of elasticity and workability.
