Abstract Carbon fiber reinforced cementitious materials, with its desirable durability and mechanical characteristics, are a high-performanced cement composite suitable for use in a variety of conditions. The use of fly-ash, polymer in carbon fiber reinforced cement can provide the composite with improved dimensional stability and reduced weight.This research has been concerned with the strength characteristics of carbon fiber reinforced Polymer cement- concrete. Effects of fiber volume fraction, polymer cement fraction and antifoaming agent on the material properties of carbon fiber reinforced cement-concrete were experimentally investigated.The results obtained from the tests were summerized as follow:1.The increase in fiber volume fraction leads to consistent increase in water absorption sorption. But polymer modified CFRPCC is improved in their characteristic with increasing P/C+A ratio.2.Compressive strength of CFRPCC tend to be reduced with increasing fiber volume fraction and specific gravity tends to be less at higher fiber contents. The best results in this investigation were obtained with Vcf=1%, P/C+A=10%.3.The increase in fiber volume fraction leads to significant improvements in flexural strength of CFRPCC. The best results in this investigation were obtained with fiber volume fraction 1% to P/C+A=10%.4.The best effective results of modification and reinforcement in this investigation were obtained with Vcf=1.0%, P/C+A=10%.
