Özet
A laboratory study was undertaken to assess the compressive and cylinder splitting tensile strength and drying shrinkage properties of concrete mixtures containing colemanite ore waste (CW). Possibility of using Kutahya-Emet CW in cement based materials as a shrinkage reducing ingredients was also discussed. Five concrete mixtures including Portland cement and CW concrete mixtures were prepared. The compressive strengths of concrete mixtures were measured at 7, 28, 56 and 90 days. The splitting tensile strength was measured at 28 days. The strength results showed that concrete mixtures containing 3 and 5% CW developed higher strength values than control concrete. The test results also showed that Kutahya-Emet CW reduced drying shrinkage of the mortar by 37% when compared to control concrete. Based on these results, it was concluded that Kutahya-Emet CW can be used as a cost-effective shrinkage-reducing agent.
