玻纤对珊瑚混凝土力学性能及耐久性的影响∗

摘要

The effect of fiberglass on coral concrete cube compressive strength, splitting tensile strength and impermeability was studied with chlorine ion flux as the evaluation indicator, and the optimal amount of glass fibers was explored. Experimental results showed that the cube compressive strength and splitting tensile strength were improved with fiberglass incorporation, but varying degrees of improvement. Glass fiber content of 1 kg/m3 , the cube compressive strength increased by the maximum of 12. 9%, when the glass fiber reached 2 kg/m3 , the splitting tensile strength increased by a maximum of 14. 3%, fiberglass incorporation had no significant effect on the impermeability of coral concrete.%研究玻璃纤维对珊瑚混凝土立方体抗压强度、劈裂抗拉强度以及以氯离子电通量作为评价指标的抗渗性的影响，并探究玻璃纤维的最佳掺量。试验研究结果为：玻璃纤维的掺入对立方体抗压强度和劈裂抗拉强度均有所改善，但改善程度不同。玻璃纤维掺量为1 kg/m3时，立方体抗压强度增幅达到最大，为12．9%；当玻璃纤维达到2 kg/m3时，劈裂抗拉强度的增幅达到最大为14．3%；玻璃纤维的掺入对珊瑚混凝土的抗渗性无显著影响。
