# In this paper, we reviewed briefly about the barrier materials for the safe disposal of radioactive waste. The primary concept of the radioactive waste disposal is safety. The goal of the radioactive waste management are to assure that the environment is not adversely affected and also public. There are wide variety of materials are available for the radioactive waste disposal or storage. Among those coal fly ash is one of the significant materials are used as barrier material. Here we reported, the Calcium sulfo aluminate (CSA) from coal fly ash is effectively suitable for the radioactive waste disposal. This is the one of way of utilization of waste and manufactured the valuable materials for future indeeds.
