短碳纤维混凝土的弹性模量及泊松比性能试验

The experimental study on modulus of static compression elasticity and poisson ratio of short carbon fiber concrete

对短切碳纤维掺量为1%,2%的混凝土的150×150×150立方体的静力受压弹性模量及泊松比进行了试验,并和未掺短切碳纤维的普通混凝土的基体静力受压弹性模量及泊松比做了比较和分析,据此研究了一定基体混凝土强度下不同碳纤维体积分数对混凝土静力受压弹性模量及泊松比变化的影响,以期为以后研究积累经验。

The static pressured elasticity modulus and pisson ratio of 150×150×150 cube concrete blended with 1% and 2% short carbon fiber were tested, which were compared and analyzed with common concrete static pressured elasticity modulus and pisson ratio without short carbon fiber. The different carbon fiber volume fraction influences on concrete static pressured elasticity modulus and pisson ratio change under certain base concrete strength were studied, so as to accumulate experience for future research.
