"Comparing the effect of Kevlar fibers and meshes on the properties of high-performance perlite concrete"
Which took place in the hall of the late Professor Dr. Munther Al-Droubi in the Department of Mechanical Engineering - College of Engineering - University of Baghdad, on Wednesday, 4/10/2023.
The study dealt with the production of several lightweight concrete mixtures from lightweight perlite aggregate and reinforcement of that concrete with Kevlar 49 fibers at different volume ratios (0, 0.5, 1, 1.5%). A lightweight concrete mixture was also produced that was reinforced with Kevlar meshes. Many laboratory tests were conducted on the concrete produced, such as workability, density, compressive strength, splitting tensile strength, thermal conductivity and flexural resistance. Slow-speed impact testing was also conducted on samples of concrete beams.
After analyzing the results, drawing relationships, and discussing the outcomes of the study, it became clear that it is possible to produce lightweight structural concrete and semi-structural insulating lightweight concrete. It also proved that the optimal percentage of fibers is 1%, while the fibers had an effect in increasing the density and increasing the thermal conductivity of this type of concrete. Kevlar meshes also played a positive role in improving the impact resistance of this type of concrete
