摘　　要：通过平板抗裂试验及RCM法研究了海工耐久混凝土的早期抗裂性与抗氯离子渗透的能力。结果表明，使用P·Ⅱ42．5硅酸盐水泥、Ⅱ区中砂、5～25mm碎石、Ⅰ级或Ⅱ级低钙粉煤灰、粒化高炉矿渣粉及新一代高性能高效减水剂可以配制出C50～C60海工耐久混凝土。The early anti-cracking behavior of marine structure durable concrete and resistance of the concrete to chlorine ion permeability attack are studied through flat slab cracking tests and RCM method. The results of the study indicate that the C50～C60 marine structure durable concrete can be well proportioned and produced by utilization of P ·Ⅱ 42.5 Portland cement, Region Ⅱ medium sand, 5～25 mm cracked stones, Grade Ⅰ or Ⅱ low calcium flyash, granulated furnace slag powder and new generation of high performance and high efficiency water reducing agent.
