Abstract:
End of life of Cathode Ray Tubes (CRT) based Televisions, Monitors etc., end up as Electronic waste and the disposal of CRT glass poses a major environmental threat, mainly due to the presence of significant Lead in the Funnel part of CRT to an extent of about 30%. The present study attempts to a Novel usage of the Funnel glass from CRTs obtained from
E-Parisaraa Pvt. Ltd., Indiaâ€™s First Government authorized E-waste recycling facility, Bangalore, Karnataka, as an aggregate
substitute in the concrete admixture for application in radiation protection areas. Various proportions of funnel glass of
CRTs were experimented by preparing M20 grade standard concrete cubes with various curing schedules. The cubes were
subjected to various load bearing standard compression tests and correlated with X-ray Radiation Protection. The study
concludes that, up to 30% funnel glass substitution as aggregate in the concrete admixtures can be successfully used for
radiation protection walls, dooms of nuclear facilities, besides can also be used for radioactive waste containment and
disposal. Accordingly we can utilize this experimental work to construct building with these cement blocks which may
control the different radiation rays which solves the hazardous waste disposal problems and it is a sustainable environmental
protections.
