Effect of Electron Beam Irradiation on Strength of Iron Slag Concrete in Different Doses
Concrete is a composite material composed of aggregate with fluid cement which hardens over time. This paper presents the effects of electron irradiation on iron slag concrete in 3 doses 15, 150 and 300 kGy. Iron slag aggregates generally have desirable properties such as soundness, strength, shape, abrasion resistance and gradation. The reason for the use of iron waste in construction is because it is useful for the economy and the environment and increase compressive strength. In this research we used cement with different percentages of iron slag by weight (5%, 15%, and 30%). Irradiation was carried out using electron beam with 10MeV energy and current of 4 mA by rhodotron accelerator. From the experimental results, it was found that the strengths have been increased with increasing the addition of iron slag. Also it is seen that the strength have been decreased with increasing the high electron doses.
