Abstract—The contribution deals with mechanical properties of functionally double layered thin slabs (totally thickness 25 mm) made from two cement-based composite materials with different properties and rupture behavior. The load bearing part of the slab was done from Ultra-High Performance Steel Fibere Reinforcement Concrete (here and after noted as UHPSFRC) with short brass coated steel fibres BASF MASTERFIBER® 482 0.2/13. The second layer of fine-grained Engineered cementitious composite (here and after noted as ECC) material with thickness about 10 mm reinforced by short PVA fibres Kuraray REC15/8 was spread on so prepared samples after 15 minutes. Total thickness of slabs was 25 mm. The performed functionally layered thin slabs were tested in a four-point bending test. The layered samples take advantage of the potential of the hi-tech UHPSFRC material and properties of the ECC matrix that thanks to the reinforcement by PVA fibres prevents a developing and spreading of micro-cracks and a getting out of steel fibres on to the surface of a structure.
