The testing of the tensil strenght concrete at bending
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 7
Abstract
The theme of this paper is the behavior analysis of the concrete girders classically armored with the addition of mineral wool fibers. The author made five sets of concrete girders of the same geometric characteristics: 12x20x250 cm and twelve concrete elements (cubes and prisms). The following parameters were tested: the strength of the classically armored concrete with the addition of mineral wool fibers, the concrete ductility and the control of cracking. The girders were loaded with the variable force: 2x5kN to 2x19 kN at the short time load after 28 days from the day of their making and at the long time load , during 365 days. The influence of the concrete , armored by the fibers mineral wool , reflected to the concrete strength at bending 16,5% .
