Effect of heat treatment on neutron attenuation characteristics of high density concretes (HDC)

Effect of elevated temperature on the mechanical properties and microstructure of heavy-weight magnetite concrete with steel fibers

“…At 120 °C, all unbound water is lost. The water loss phenomena reduce the neutron attenuation of the radiation-shielding concrete [26,27]. In the temperature interval of 180-300 ºC, the first stages of dehydration of the C-S-H gel begin due to the loss of bound water [28].…”
