Abstract
This study was carried out for designing concrete which has ability to resist the effects of nuclear explosions, this leads to discuss theses effects (blast, thermal, radiation and so on). The present study has been carried out with a view to establish the basic engineering data and information about the technology of heavy weight concrete from local materials. It can be used as shielding materials because of its potential properties, radiation attenuation, mechanical characteristics, durability and economic structural use. In this study, Ilmenite is used as coarse aggregate; serpentine is used as fine aggregate mixed with normal Portland cement and water. Also steel fibers were added with different percentages.
Different concrete mixes were designed, produced, cured, and tested for compressive, tensile, flexural, ultrasonic test and impact strength. Admixtures were employed to improve the mechanical properties. The results showed that the steel fiber Ilmenite-serpentine heavy weight concrete has good mechanical properties for construction of nuclear shelters. Results show that Ilmenite-serpentine heavy weight concrete has good mechanical property compared with the ordinary concrete in most of tests specially the tensile and flexural strengths. It has been found that the ISFHWC can be produced with a maximum density of the order 3.35 t/m3. Also, results show that Ilmenite-serpentine heavy weight concrete of suitable thickness will improve the impact strength more than the ordinary concrete with high values.
