Abstract

New heavy weight concrete is proposed to be used in shelters to protect airplanes against shock wave and radiation emitted during nuclear bursts specially gamma and neutrons. In this study, ilmenite is used as a coarse aggregate and serpentine is used as fine aggregate. Different concrete mixes were designed, produced, cured and tested to study the effect of gamma radiation up to 1000 M Rad and temperature up to 500°C. The results showed that the effect of heating and irradiation on the compressive strength of concrete depends on the elemental composition and on the moisture content of the concrete components.
