碳纤维增强混凝土抗压强度变化规律研究

Experimental Study on Basic Mechanical Properties of C30 Carbon Fiber Reinforced Concrete

对0.05%,0.10%,0.15%,0.20%等四种不同掺量碳纤维在C30混凝土中发挥的作用和对混凝土基本力学性能的影响进行了试验研究。结果表明,随着碳纤维掺量的增加,C30混凝土基本力学性能有了较大的变化,表现为抗拉强度逐渐增大,抗压强度逐渐降低,0.20%体积率下的抗拉强度达到最大值,而抗压强度达到最低值。

The effects of different carbon fibers adding content （0.10%, 0.15%, 0.20%） on the mechanical properties of C30 concrete were studied. The results show that with the increase of the carbon fiber, the basic mechanical properties of concrete C30 has a lot of changes for the flexural strength increases, the compressive strength decreases and the flexural strength reaches the maximum value in the 0.20% volume rate, while the compressive strength reaches the lowest value.
