Abstract: This study is to investigate experimentally fire resistance of flat slab manufactured using recycled crushed ceramics as coarse aggregate. From an economic point of view, this experiment is costly; however, if it managed and done correctly it can save raw materials, and conserve natural resources. The test is carried out on six slabs measuring 1.65*1.65*0.15m tested under flexural load exposed to fire under load for about 120 min. Two slabs were control without recycled ceramics aggregate, one slab with recycled ceramics aggregate with ratio of 35%, and three slabs with different ratios of 20%, 35% and 50% cast in layers such that the lower layer which was exposed to fire contains crushed ceramics, and the upper layer from ordinary concrete. This paper examines the feasibility of using ceramics wastes in concrete. The behavior of R.C flat slabs manufactured with recycled crushed ceramics was similar to that the normal concrete.
