In this study, it has been planned to produce light-weight aggregates and lightweight concrete from fly ash of Seyitomer Thermal Power Plant. After the specifiying of the physical and chemical properties of fly ash, various types of pellets were produced from lime and gypsum which are mixed of five different rates. The most durable pellets were found to consist of fly ash (88%), lime (6%) and gypsum (6%) mixture. Three types of light-weight concrete have been produced by mixing different rates of Portland cement (16%, 20%, 24%) with the light-weight aggregates. The concretes have been subjected to several mechanical tests after certain durations of time (1, 3, 7, 14 and 28 days). Compressive strength and flexural tensile strength have been investigated in mechanical tests. The volumetric unit weights of the concrete samples remained below 2 ton/m3. According to the mechanical tests, the light-weight concrete with 20 % cement addition has been found to be much more durable.
