Abstract

Highlights: CRT waste glass was recycled as fine aggregate for heavyweight filling material. The durability of the filling material is better than in normal mortar. The linear attenuation coefficient of the filling material increased by 2.56 times. The filling material have good potential for use in radioactive disposal facilities. Abstract: Environmental problems caused by municipal and industrial waste are serious worldwide. In particular, landfill of recyclable industrial waste due to a lack of technology is a serious loss of resources. Heavyweight waste glass is an industrial waste that has been studied by many researchers for use as a fine aggregate. Until now, the heavy metal is removed through complex pretreatment. However, in this study, the waste glass was recycled through a simple crushing process without pretreatment. We investigated the fundamental properties, durability, and shielding property of filling material containing waste glass. The test results show that the durability and shielding property were all better than in ordinary mortar. Also, the reduction in strengths, and the expansion due to ASR, can be solved by using a mineral admixture. In conclusion, mortar containing a mineral admixture and waste glass is considered to be viable as filling material in radioactive waste disposal facilities.
