Abstract: 
An experimental program has been conducted at the laboratories at NTNU including small-scale tests on fibre reinforced lightweight concrete (FRLWC) and 4-point beam tests on larger hybrid concrete beams. The hybrid beams consisted of layers of FRLWC and normal concrete (NC). The small-scale tests included uni-axial tension tests (UATT) and 3-point bending tests (3PBT). Fibre counting has also been carried out. Material parameters influenced by the fibre content obtained in the small-scale tests constitute the basis for design of hybrid concrete beams.
