Development trend of radiation shielding concrete

The use of radiation is common in many fields of applications including in nuclear reactors,different types of industries and medicine.The potential impact of radiation on the environment and human health are of significant concern.This article presents a review of research efforts that have been made on developing radiation shield concrete in China and overseas countries.The review covers raw materials selection,effects of mineral admixtures on concrete properties,mix design,and long-term performance of the concrete.The current problems and research gasps are analyzed.A new technique of utilizing crushed leaded glass derived from waste cathode ray tubes(CRT) is proposed for the development of the radiation shielding concrete.
