The flexural behavior of multi-layer high performance self-compacting hybrid fibers concrete slabs

Fiber concretes are a new type of composite material in the manufacturing industry, due to lack of information, identification behavioral characteristics requires laboratory studies. In this research, the bending behavior one layer and multi-layer slabs made with high performance self-compacting con...
