“…The polypropylene fiber market reached $122.7 billion in 2019 [14]. Many studies have been conducted to investigate the improvement of PPFincorporated cement-based materials' performance [15][16][17][18], especially the improvement in mechanical properties [19][20][21][22]. The addition of PPF can significantly reduce the drying shrinkage while improving the compressive strength and freeze-thaw resistance of concrete [23].…”

In this work, the relationships between the mechanical properties (i.e., compressive strength and flexural strength) and loading speed of polypropylene fiber (PPF)-incorporated cement mortar at different ages (before 28 days) were studied. A total of 162 cubic samples for compressive strength tests and 162 cuboid samples for flexural strength tests were casted and tested. Analytical relationships between the sample properties (i.e., sample age, PPF content, and loading speed) and compressive and flexural strength were proposed based on the experimental data, respectively. Of the predicted compressive and flexural strength results, 70.4% and 75.9% showed less than 15% relative error compared with the experimental results, respectively.

“…Therefore the number of articles is dedicated to usage of modern materials in order to ensure reliable RC structures` exploitation (Khmil et al, 2021a). Due to the depletion of their resources, many structures need to be restored and strengthened (Lipinski, 2017;Nikolic et al, 2020;Turba and Solodkyy;2021). According to modern technologies, a lot of RC structures are strengthened with the use of various composite materials (Vatulia et al, 2019;Vavrus and Kotes, 2019), reinforced concrete jacketing (Khmil et al, 2021b), external steel sheets, etc.…”

This article presents the materials of deformability studies of pre-stressed steel-concrete beams reinforced with a package of reinforcement with different ratio of tape and rebar in the pure bending moment zone. The aim of the research was determination of the reinforcement percentage influence, for pre-stressed reinforced concrete beams reinforced with a package of reinforcement on their deformability. Also, the aim was to evaluate the effectiveness of using pre-stressed rebar in combined reinforcement. The practical significance of the experimental research is to study the deformability in pre-stressed bending elements with external tape and rebar reinforcement, taking into account the influence of different ratios of reinforcement areas within the combined reinforcement and development of proposals for such structures` calculation and design. The scientific novelty of the research is in obtaining the deformability characteristics of reinforced concrete beams reinforced with a package of reinforcement (tape and steel bars with periodic profile) with different ratios in the case of static loads` action.

“…Particular attention should be paid to the establishment of residual load-bearing capacity of structures in which new materials are proposed (for example, composite (Turba and Solodkyy, 2021;Vavrus and Kotes, 2019)), as well as for structures with complex stress-strain state (such as pre-stressed structures (Bobalo et al, 2021)).…”

Each structure is exposed to different influences during operation. As a result, there are various defects and damages of these elements that affect their safe operation. The article presents the results of experimental studies of reinforced concrete beams with damages to stretched reinforcement made with and without initial load application. As the damages were accepted one or five Ø5.6 mm holes. In one case, the damage was made until the beam destruction (up to the 8.4 mm opening) Control samples of both series were destroyed due to crushing of the compressed zone of concrete. Samples that were damaged without initial loading collapsed due to rupture of the stretched reinforcement. The same type of failure was identified for damages at the operational load level.
