We have developed Anti- Sievert® concrete, which is a concrete reinforced shielding function as a building material that shields the influence from radioactive materials and its radiation. Cement, water, aggregate, sand material, Anti- Sievert® # 210, Anti- Sievert® # 216 formulation was optimized as those materials constituting Anti- Sievert® concrete. As a result, we realized shielding concrete with high fluidity to realize construction suitability by concrete pump. Anti- Sievert® concrete has a shielding function of about 3 times as compared with ordinary concrete with respect to X ray (100 kV), and shows strength of more than 50 N/mm2. The durability characteristics against nuclear explosion using Anti-Sievert® concrete were simulated and reported in this paper.
