Abstract
Provided is a protective concrete for weaken the intensity of proton radiation, and it is prepared by mixing 525# cement 500-700 Kg; barite sand 1000-1400 kg, barite stone 1500-1800 Kg, lead powder 180-200 Kg and water 170-180 Kg. The barite that can absorb the proton radiation is used, so the present concrete is much better than conventional concretes in weakening the proton radiation, and 1.5 m-thick wall without lead plates which is prepared with the present concrete can achieve the same effect on weakening the proton radiation with a conventional 2 m-thick wall covering with lead plates.
