Over the past two decades, successful attempts were made to produce field concrete with compressive strength surpassing 100 MPa. Meanwhile, other attempts succeeded in producing engineered cementitious composites (ECC) of relatively higher ductility. There is still a need to produce concrete that possessed both high strength coupled with relatively high ductility. This work aims at producing High Strength/ High Ductility Concrete (HSHDC) using materials from different sources and compare them to a conventionally produced concrete. Three types of cement, two oil well cement and one ordinary Portland cement, were used together with un-densified silica fume. Polypropylene and polyethylene fibers were incorporated at volume fractions. The experimental work covered a set of tests to obtain the material properties. Several tests were done to evaluate the strength, ductility, toughness and durability of these concrete mixes. Results suggest that most of the produced mixes achieved the desired qualities, which are having strength above 50MPa and at the same time possessing high ductility. The use of oil well cement with addition of fibers yielded the best performing HSHDC. The use of latex showed promising results in some of the properties but it yielded lower toughness.
