Mechanical Properties of Functionally Layered Thin Slabs

Popis výsledku v původním jazyce

The contribution deals with properties of thin slabs made from two different cement-based composite materials. The load bearing part of the slab was done from Ultra-High Performance Steel Fibre Reinforcement Concrete (UHPSFRC) with short brass coated steel fibres BASF MASTERFIBER® 482 0.2/13. After 15 minutes the layer of fine-grained ECC material with thickness about 10 mm reinforced by PVA fibres Kuraray REC15/8 was spread on so prepared samples with total thickness of 25 mm. Homogeneous slabs made from UHPSFRC and from ECC with thickness about 25 mm were prepared except the functionally layered samples. The performed 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.
