Investigation of mechanisms of radiolytic H2 production in C-S-H: Influence of water content and radiation induced defects

Water radiolysis is a major concern for the conditioning of radioactive waste in cement materials. Synthetic calcium silicate hydrates (C-S-H), main concrete, were synthesized with different to ratios and relative humidity. The samples irradiated under γ- electron beam irradiation. radiolytic hydrogen production was quantified radiation induced defect produced at low temperature characterized by paramagnetic resonance. results show that H2 are 20% sensitive
