Effect of Different Fibers and Mineral Additions on the Performance of FRSCC
This paper describes how several self-compacting concretes were prepared by using three different types of fibers made of steel, poly-vinyl-alcohol (PVA), high toughness poly-propylene (PPHT), and two different types of mineral addition (limestone powder and powder from recycled concrete). The water-cement ratio (w/c) was in every case equal to 0.40. Fresh concrete behavior was evaluated by means of slump flow, V-funnel, and L-box tests while the hardened concrete behavior was evaluated by means of flexure and compression tests as well as free drying and restrained plastic shrinkage measurements. Excellent performances were generally detected, particularly for the self-compacting concretes prepared with steel and PPHT fibers.
