In order to explore the feasibility of using hazardous waste cathode ray tube (CRT) funnel glass to replace high density mineral aggregates in the radiation shielding concrete, various barite concrete samples were prepared with portland cement, ground funnel glass sand as the substitute for barite aggregates, and fly ash as mineral admixtures, and the rates of funnel glass for fine and coarse (5–10 mm) barite aggregate were 25%, 50%, 75%, 100% and 10%, 20%, 30%, respectively. The work performance, mechanical properties, dry shrinkage, alkali-silica reaction (ASR) expansion and lead leaching were investigated, and the γ-ray attenuation coefficients were obtained by experiment, XCOM program and MCNP code. The results show that the slump, ASR expansion and lead leaching of the concrete increase while its apparent density, mechanical properties, dry shrinkage, and γ-ray shielding properties decrease with the increase of the rate of funnel glass. Adding fly ash to the concrete can inhibit the leaching of Pb, and reduce the ASR expansion. The concrete samples with 25–50% fine funnel glass sand or 10–20% 5–10 mm coarse aggregate have good performances. The results show that it’s efficient, economical and environmental-benign to use funnel glass to produce the high density radiation shielding concrete.
