Özet:

 Concrete waste is one of the major components of construction and demolition wastes, as well as a material that must be removed in an environmentally safe manner. With the inclusion of concrete waste as a minor additional constituent, the popularity of its utilization has gained importance. This study utilizes concrete waste with replacement ratios of 20, 40, and 60, in both calcined and non-calcined forms. Two different calcination temperatures were applied to see the effect of calcination temperatures. Results show that as the replacement ratio of non-calcined concrete waste increases, mechanical performance decreases. However, calcination enhances the reactivity of concrete waste, and at an optimum replacement ratio of 20, the compressive strength is higher than that of the reference specimen. After freeze-thaw cycles, specimens with 20 calcined concrete waste exhibit lower compressive strength losses compared to the reference specimen. Regarding the mass losses after freeze-thaw cycles, 20 concrete waste calcined at 950 C have better performance than reference specimen. This study shows that with a 20 replacement ratio, calcined concrete waste can be used as a cement replacement material.
