Method for determining chloride ion diffusion coefficient of fiber reinforced concrete
The invention provides a method for determining a chloride ion diffusion coefficient of fiber-reinforced concrete, which comprises the following steps: regarding the fiber-reinforced concrete as a five-phase heterogeneous material comprising gravel aggregate, fiber, cement paste, a gravel aggregate-cement paste interface transition region and a fiber-cement paste interface transition region, determining the volume ratio of five-phase components in the fiber reinforced concrete; and obtaining the chloride ion diffusion coefficient of the fiber reinforced concrete based on the volume ratio of the five-phase components and the chloride ion diffusion coefficient of each phase component. According to the method, the chloride ion diffusion coefficient of the fiber reinforced concrete can be accurately predicted, and reference is provided for proportion design of the fiber reinforced concrete.
本发明提供一种纤维增强混凝土氯离子扩散系数确定方法，包括：将纤维增强混凝土视为包含砂石骨料、纤维、水泥浆体、砂石骨料‑水泥浆体界面过渡区和纤维‑水泥浆体界面过渡区的五相非均质材料，确定纤维增强混凝土中五相组分的体积占比；基于五相组分的体积占比以及各相组分的氯离子扩散系数，得到纤维增强混凝土的氯离子扩散系数。本发明能够较为准确地预测纤维增强混凝土的氯离子扩散系数，为纤维增强混凝土的配比设计提供参考和借鉴。
