Properties of green high performance concrete reinforced with different fibers

An experimental work was carried out to investigate the mechanical properties of Green High Performance Concrete (GHPC) reinforced individually with three different types of fibers such as polypropylene fiber (PPF) ,carbon fiber (CF), and glass fiber (GF) with volume fractions 0.3%,0.6%,and 1%. For this, GHPC mixtures were produced using silica fume (SF) at 20 percent as a partial substitute by cement weight, in addition to using the super plasticizer (SP) to obtain the appropriate workability with low w/b ratio. A constant w/b ratio of 0.35 was used for the produced mixtures, and in order to control the workability of the mixtures, the super plasticizer ratios were modified. Standard curing was used in this study, then the specimens were tested for compressive strength and flexural strengths. The results show that the blends reinforced with polypropylene fiber, carbon fiber, and glass fiber with fractions of volume of 1%, 0.6 %, and 0.3 %, respectively, demonstrated the highest compressive and flexural strength.
