Variation of chloride-permeation resistance of concrete for ocean construction with time at early ages was studied through measurement of compressive strength,chloride permeability and pore structure.

50时,海工混凝土早龄期抗氯离子渗透能力远小于它们的28 d抗氯离子渗透能力,且其随龄期变化规律不同于抗压强度随龄期的变化规律;在早龄期时由于海工混凝土的孔隙率高、孔径大于50 nm的大孔数量多,因此其抗氯离子渗透能力较弱;尽管在设计海工混凝土时选用了高抗氯离子渗透能力的高性能混凝土,但其在早龄期时也不具有抗氯离子渗透能力。
