Several critical studies have recently focused on the recycling of industrial waste materials owing to their storage problems. Considering the increase in supply and demand for aggregate and limited natural raw materials, researchers have focused on producing artificial aggregates with low energy usage and environmental friendliness. Therefore, industrial wastes, such as fly ash, are being used for artificial light aggregate production. In this study, fly ash was obtained from a Yatagan thermal power plant used in light-coarse aggregate production. A mould was designed to produce aggregates with an 18-mm diameter geometry between a cube and a sphere using the cold binding method. The mould was designed to generate a fly ash aggregate (FAA) through a pressing way without a sintering process. Aggregate production is based on a homogenous mixture of mainly fly ash, Portland cement, and water. The strength and availability of the aggregates produced in concrete were tested in several ageing tests (freezing-thawing, wetting-drying, and outdoor exposure). In general, it has been found that there are no significant changes in the physico-mechanical values after 160 wetting-drying cycles on FAA concrete samples. In 1080-day outdoor testing, FAA concrete examples performed better than conventional concrete samples. In addition, the density of fly ash aggregates is about 1.83 g/cm(3), and that of limestone aggregates is 2.69 g/cm(3).
