摘要：

High temperature can cause serious damage to building structures, so it is important in order to re-evaluate the residual properties of radiation shielding concrete (RSC) exposed to elevated temperatures for ensuring security of medical, industrial and defense building structures. Thus, the deterioration of the mechanical, gamma-ray shielding properties and acoustic emission character-istics of barite concrete (BC) and magnetite concrete (MC) exposed to elevated temperatures were studied. Research indicated that the performance of aggregates played a crucial role in the thermal stability, resi...
