Study on basic mechanics and constitutive relation of uniaxial compression of carbon fiber reinforced concrete
MENG Wenhua
Abstract：The effect of carbon fiber volume on the basic mechanical properties and compressive constitutive relationship of concrete was investigated by experiments. The test results show that with the increase of carbon fiber content,tensile strength,flexural strength and axial compressive strength of concrete first increase then decrease,the peak strain and ultimate strain of concrete increase gradually. The tensile strength and flexural strength of concrete with 0.8% carbon fiber content reach the highest, in-creased by 30.6% and 19.1%,respectively. The parameter a of the rising curve of concrete compressive constitutive curve is less affected by the amount of carbon fiber,but the decline curve of b decreases gradually with the increase of carbon fiber content, and the curve of the falling section of concrete tends to be gentle,concrete ductility increases gradually.
