This paper provides a review about the thermal and radiation shielding properties of geopolymer concrete. Geopolymer concrete is a type of concrete that is made by reacting aluminate and silicate bearing materials with a caustic activator. commonly, waste materials such as fly ash or slag from iron and metal production are used which helps to lead a cleaner environment. Radiation-shielding concrete (RSC) is used in nuclear power plants, health care facilities in conducting radiation therapy, nuclear research facilities, and storage/transport casks for radioactive waste. In RSC mixtures, high-density aggregates are used to attenuate gamma rays and light atomic weight aggregates are used to absorb neutrons, so their properties and proportions will affect a mixture’s radiation-shielding characteristics. Heavyweight concrete is extensively used as a shield in nuclear plants, radio therapy rooms and for transporting as well as storing radioactive wastes. For this purpose, concrete must have high strength and density. Heavyweight and high strength concrete can be used for shielding purposes. Such concrete with magnetite aggregates can have a density in the range of 3.2–4 t/m3, which is significantly higher than that with normal aggregates.
