СARRYING CAPACITY OF BENDING CONCRETE ELEMENTS REINFORCED BY FIBRO AND STRIPES TAKEN FROM USED POLYETHYLENE TEREPHTHALATE BOTTLES
Journal Title: World Science - Year 2018, Vol 1, Issue 2
Abstract
The results of prisms tests from fine-grained concrete in the sizes 400 mm x 100 mm x 100 mm on compression and three-point bend for a run 350 mm are submitted. The average cubic strength of the concrete was 31.21 MPa, of the prism - 23.23 MPa. The average flexural strength of the prism without a fibre is 58.54 kN • cm, with a PET fabric of 50 mm x 3 mm x 0.2 mm - 64 kN • cm and 71, 84 kN • cm for the percentage of reinforcement 1 and 1.5 respectively. The average flexural strength of the prism, reinforced with strips, made of 4 glued fragments of PET bottles in the sizes 200x80x0.25 mm - 79, 80 kN • cm. The destruction of fibrous concrete prisms was viscous, and prisms, reinforced with stripes, were fragile. The necessity of developing a deformation method for calculating PET-fiber-reinforced concrete bending elements, as well as the need to find ways to improve the adhesion of PET strips with concrete is shown.
