Replacement of Polymer Fibers with Hemp Fibers in Concrete

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
Abstract In our experiment, we tried to replace polymer fibers with hemp fibers and verify whether the properties and advantages of polymer fibers in concrete will be retained even with this interchange. Polymer fibers are added to the mixer to produce fresh concrete or mortar, and we did the same in our case.

Investigation of the use of hemp fibers in recycling spinning

open access: yesActa Scientiarum: Technology, 2023
In recycle yarn spinning, the original fibers are added to the blend as a carrier because of the recycled fibers obtained by opening from fabric scraps are very short and coarse. In the textile recycling industry, mostly petroleum-based synthetic fibers
