Název v původním jazyce

Experimental tests of fiber-reinforced concrete slabs and comparison of deformations using 3D graphs

Popis výsledku v původním jazyce

The presented article deals with experimental testing of fiber-reinforced concrete slabs using a specialized testing device, the so-called Stand. The experimental testing involved a total of three slabs with different fiber dosing. Dosing was chosen of 25, 50, and 75 kg/m3. In the case of fiber dosing of 75 kg/m3, the concrete recipe was changed with regard of fiber dosing. The test equipment allows vertical loading of the elements and, together with the installed track sensors and computer technology, records the vertical deformations. The deformation of the slabs was evaluated using 2D deformation sections in the slabs of mounted sensors and using 3D deformation sections with the use of interpolation of intermediate values. The article is supplemented by a test evaluation of the mechanical properties. These were concrete compressive strength, modulus of elasticity, and tensile strength. The mechanical properties were also tested and evaluated for plain concrete (dosage 0 kg/m3). By evaluating the mechanical properties and deformations, it is possible to observe differences in the behavior of fiber-reinforced concrete elements for different degrees of fiber reinforcement. The article evaluates the positive effect of fibers on the load capacity and the deformations of slabs. (C) 2021 Sciendo. All rights reserved.
