摘要

This paper presents the results of an experimental/analytical investigation on the development of eco-efficient and cost-effective self-consolidation concretes reinforced with hybrid steel industrial and recycled fibers. Particularly, eleven mixtures containing different combinations of the hybrid industrial/recycled steel fibers were cast and examined under the compressive, tensile, flexural, and the repeated drop weight impact tests. Then, the mechanical properties were correlated to the resistance to impact actions. The effects of fiber combinations on the cost and the released carbon emission into the atmosphere were studied. Finally, a simplified optimization approach was used to obtain the eco-efficiency and cost-effectiveness of the fiber-reinforced self-consolidation concrete.
