The influence of steel fibers obtained by recycling waste tires on the properties of concrete
Апстракт
The paper shows the influence of steel fibers obtained from steel wire separated in the recycling process of waste car tires on the properties of concrete. The reference concrete was prepared, as well as concretes with the addition of steel fibers, which were varied in contents at 20 kg/m3 and 40 kg/m3. The slump test of fresh concrete was performed using the Webe method, where it was established that with an increase in the amount of fibers, concretes with a stiffer consistency are obtained. Concrete beams were tested for strength during flexure tension (limit of proportionality (LOP) and residual flexural strength).
Can be concluded that the residual flexure strength greater than 1.5 MPa at a CMOD of 0.5 mm is already achieved with the addition of 20 kg of fibers per m3 of concrete, while both conditions for the residual bending strengths are satisfied with the addition of 40 kg of fibers per m3 of concrete and that they amount to 2.4 MPa at a CMOD of 0.5 mm and 1.4 MPa at a CMOD of... 3.5 mm.
