In this study, structural lightweight concrete mixtures are produced by using Kayseri pumice aggregate. The other constituent materials used in producing the lightweight concrete mixtures are; CEM I 42.5 cement as binder, silica fume and fly ash as mineral admixtures. The following properties are determined; slump, unit weight and air content of fresh mix, as well as unit weight, compressive strength, splitting tensile strength and flexural strength of hardened concrete. Test results show that the lightweight concrete mixtures prepared from Kayseri pumice have compressive strength far above 17.2 MPa proposed by ACI 213R-87 for structural lightweight concrete. Besides, the lightweight concretes produced in this study meet LC 20/22 and LC 25/28 strength classes given by TS EN 206-1.
