    摘要:

    采用纳米压痕和劈裂试验方法，研究了珊瑚骨料与水泥净浆界面试件在不同养护龄期的纳米压痕弹性模量、纳米压痕硬度、界面黏结劈拉强度、水泥净浆抗压强度和劈拉强度，以及它们之间的相关性.结果表明：与普通混凝土类似，珊瑚混凝土存在薄弱的界面过渡区(ITZ)，内掺10%珊瑚微粉能够强化珊瑚骨料水泥净浆界面的宏观和纳米力学性能，界面黏结劈拉强度不仅与水泥净浆抗压强度、劈拉强度间存在显著线性关系，还与ITZ、水泥净浆基体的纳米力学性能有显著相关性.

    Abstract:

    Nano indentation and splitting test were used to study the nano indentation elastic modulus, nano indentation hardness, interface bond splitting tensile strength, cement paste tensile strength and compressive strength and correlation of coral aggregate and cement paste interface specimens at different ages. The results show that similar to ordinary concrete, coral concrete has a weak interface transition zone(ITZ). Adding 10% coral micro powder can strengthen the macro and nano mechanical properties of ITZ. The interface bond splitting tensile strength is not only linearly related to the compressive strength or splitting tensile strength of the cement paste matrix, but also to nanometer mechanical properties of interface transition zone and cement paste matrix.
