This paper presents an experimental investigation on the behavior of six   reinforced concrete columns under elevated temperature. An expanded clay aggregate (LECA) was used in three ,other remain natural .All RC have similar cross sectional dimensions 150mm ×150 mm (width× height); and 1250mm total length. The were designed according to ACI Committee 318-2014 exposed different temper...
