In this study, Influence of plastic aggregate and curing condition on the mechanical properties of concrete containing silica fume has been investigated. Concretes included silica fume (SF) as a cement replacement levels of 10% and 15% and contain plastic waste aggregate (PWA) as a natural aggregate (NA) replacement. In this study plastic fine aggregate (PF) and plastic coarse aggregate (PC) are replaced at NA. The w/b ratio and total cementitious materials content were kept constant for all mixes at 0.50 and 350 kg/m3 respectively. Concrete mixes were evaluated for compressive and tensile strengths at 7, 28 and 90 days in two different environment: a) laboratory environment (LE) and b) out (Marine) environment (ME/OE). The results show that Concretes containing silica fume compressive strength decreases with increasing of PWA as a replacement and outdoor condition is more important for surveying curing position.
