Abstract
This paper presents the result of a study on the use of natural materials(saw dust, rice husk,and sugar cane bagasse)for removing of some radionuclides from liquid radioactive waste. Contaminated natural materials used are saw dust, rice husk and bagasse which were used as untreated species and treated species (treated by KOH, HCl).These natural materials were solidified into ordinary Portland cement.Compressive strength of the final solid waste blocks has been performed. Effect of temperature, different additives types (with and without treatment) and different additives weights on the compressive strength has been carried out. At 50°C the compressive strength for samples contain untreated saw dust, rice husk and bagasse was 76, 25 and 45KN respectively, while at 200 °C compressive strength was 120, 20 and 40KN respectively
