Radiation-proof material
The invention provides an anti-radiation material which comprises a binding material, water, an additive and a barium-based material, the binding material comprises cement and fly ash, the additive comprises a water reducing agent and alkali-resistant fibers, the barium-based material comprises a first barium-based material and a second barium-based material, or the barium-based material comprises a first barium-based material and a third barium-based material, and the binding material comprises cement and fly ash. The particle size of the first barium-based material is 0-3mm, and the apparent density is greater than or equal to 4000 kg/m < 3 >; the particle size of the second barium-based material is 5-25 mm, and the apparent density is greater than or equal to 4000 kg/m < 3 >; the particle size of the third barium-based material is 0-0.5 mm, and the apparent density of the third barium-based material is greater than or equal to 4200kg/m < 3 >. The anti-radiation material provided by the invention is high in protective lead equivalent, free of any lead-containing material, non-toxic, good in environmental protection property, excellent in crack resistance and stable in anti-radiation performance.
本公开提供了一种防辐射材料，包括：胶凝材料、水、外加剂以及钡基材料，所述胶凝材料包括水泥和粉煤灰，外加剂包括减水剂和耐碱纤维，所述钡基材料包括第一钡基材料和第二钡基材料，或所述钡基材料包括第一钡基材料和第三钡基材料，所述第一钡基材料的粒径为0‑3mm，表观密度大于等于4000kg/m3；所述第二钡基材料的粒径为5‑25mm，表观密度大于等于4000kg/m3；所述第三钡基材料的粒径为0‑0.5mm，所述第三钡基材料的表观密度大于等于4200kg/m3。本公开提供的防辐射材料防护铅当量高，防辐射材料中不含任何含铅材料，无毒且环保性好，抗裂性能优良，防辐射性能稳定。
