Protective engineering concrete for weaking proton radiation strength

This invention provides a protection work concrete of weakening proton radiation. It is mixed by the following materials: number 525 cement 500-700 kg; Barite sand 1000-1400 kg; Barite cobble 1500 -1800 kg; ceruse 180-200 kg; Water 170 - 180 k. The invention use barite that has good proton ray absorption, therefore, its anti-proton radiation effect greatly superior to the traditional concrete. The pouring concrete wall thickness of 1.5 meters, not using radiation protection grid, will be able to achieve the radiation protecting effect of two-meter thick wall with radiation protection grid of abroad outsourcing.
