    • PURPOSE: A fiber-reinforced concrete composition for an atomic power plant containment building is provided to reinforce toughness and shock resistance of the atomic power plant containment building. CONSTITUTION: A fiber-reinforced concrete composition for an atomic power plant containment building contains cement, aggregate, and a blending material. The water-binder ratio of the concrete composition is 30-50%. The concrete composition includes 10-30 parts by weight of fly ash based on 100 parts by weight of cement. A fibrous reinforcement material(100) is mixed at 0.01-2.00 wt% based on the total weight of the concrete composition. The fibrous reinforcement material is composed of hydrophilic fibers. A coating layer(120) is formed on the surface of the fibrous reinforcement material by hydrophobic surfactant. The fibrous reinforcement material has the length of 5-200mm and the diameter of 0.01-20mm.
