碳纤维混凝土的力学性能试验研究

The Experimental Study on Mechanical Properties of Short Carbon Fiber Concrete

通过试验,对短切碳纤维掺量为1%,2%的混凝土的150 mm×150 mm×150 mm立方体和150 mm×150mm×300 mm棱柱体试块的抗压强度、劈拉强度、静力受压弹性模量、泊松比等进行了试验,并和未掺短切碳纤维的普通混凝土的基体做了比较和分析,据此研究分析了一定基体混凝土强度下不同碳纤维体积分数对混凝土力学性能等变化的影响。

The compressive strength and splitting tensile strength and modulus of static compression elasticity and Poisson＇s ratio of the 150 mm×150 mm×150 mm concrete cube and 150 mm×150 mm×300 mm concrete prism with 1% and 2% mixing amount of short carbon fiber were tested and compared with ordinary concrete matrix without short carbon fiber,to analyze the effect of different added amount carbon fiber on mechanical properties of concrete under the same matrix strength.
