Abstract—This paper presents a review on the high performance high volume flyash concrete reinforced with hybrid fibers. It is well known that manufacturing of one ton of Ordinary Portland Cement (OPC) absorbs about 4GJ energy and produces about 750kg to 1000 kg of CO₂ to the aerosphere and is claimed to affect ozone layers and lead to global warming. Researchers have tried to substitute fly ash for cement which generally leads to lower strength. Fibers in general have been used in recent years, mainly to toughen and strengthen the concrete matrices and to enhance the shrinkage cracking resistance. However, more research is required on the mechanical and durability properties of high performance high volume flyash concrete reinforced with hybrid fibers, as very little research or experimental work is reported in the literature. This paper investigates the provision of three different fibers; steel, polypropylene and basalt in individual and in hybrid form. Analysis shows that performance enhancement can be obtained by using fibers in hybrid form.
