The worldwide energy crisis and environmental deterioration are probably humanity's
greatest challenges. Thermoelectricity, which allows for the mutual conversion between …

Cesium-137 is a common radioactive byproduct found in nuclear spent fuel. Given its 30
year half life, its interactions with potential storage materials—such as cement paste—is of …

The paper characterizes concurrent effects of gamma-irradiation and presence of water in
Portland cement pastes. An extensive nanomechanical quantification (Young's modulus …

The long-lived (billions of years) 40 K, 235 U, 238 U, and 232 Th isotopes have a high
energy capacity and represent a potent internal source of energy. Together with the external …

Water radiolysis is a major concern for the conditioning of radioactive waste in cement
materials. Synthetic calcium silicate hydrates (CSH), the main hydrates of concrete, were …

This study investigates novel Portland cement-based mortars, developed for
hydrogen/tritium trapping and radioactive waste immobilization. They incorporate a γ-MnO …

Blended cements with high content of blast furnace slag (CEM III/C) can be used for nuclear
waste conditioning because of their low hydration heat as compared to ordinary Portland …

Water radiolysis is of particular concern for the conditioning of radioactive waste with cement
materials. For safety assessment, water radiolysis issued from pore solution and hydrates …

Radiation, heat and carbonation can all affect the performance of concrete structures. This
study applies either a 1.5 MGy gamma radiation dose or thermal treatment at 60° C, followed …

Buildings are responsible for a considerable fraction of the energy wasted globally every
year, and as a result, excess carbon emissions. While heat is lost directly in colder months …
