| Description | Its a manufacturing process. The technology of fiber reinforced concrete using polypropylene fibers treated with low-temperature plasma for application to concrete keystone for tunnel lining segment linear structures. Concrete with the addition of PP fibers treated by nízkoteploního plasma for the manufacture of precast keystone. Bulk density of fresh concrete was 2420 kg/m3. The consistency of concrete is F2. Concrete class according to EN 206-1: C40/50, F2, density of hardened concrete. 2390 kg/m3. The average compressive strength after 28 days of curing 69 MPa, tensile bending strength of 5.5 MPa. |
