Research Institute completes project to develop polymer fibers to improve reinforced concrete properties - Sarmad

(KUNA) – The Kuwait Institute for Scientific Research announced on Sunday the completion of a research project aimed at developing synthetic polymer fibers from polypropylene and polyethylene to enhance the properties of reinforced concrete and improve its resistance to impacts and cracking.

In a press release, the institute stated that the project was carried out by the Petroleum Research Center, under the directorship of Dr. Salah Al-Anzi, Head of the Petrochemicals and Materials Technology Program, in collaboration with Equate Petrochemical Company and with support from the Kuwait Foundation for the Advancement of Sciences.

It clarified that the project’s results led to the development of polymer fibers from polypropylene and linear low-density polyethylene (PP/LLDPE) blends, which are suitable for manufacturing and use in concrete.

The institute added that tests showed improved impact resistance of fiber-reinforced concrete, along with increased durability and load-bearing capacity after cracking, with only a limited effect on its compressive strength.

It noted that the project aims to maximize the added value of locally available polymers by converting them into specialized engineering products that support the construction and national industrial sectors.

The institute pointed out that the project’s outputs included identifying potential applications for the developed fibers in industrial flooring, pavements, and precast concrete elements, as well as submitting a scientific paper for publication in the peer-reviewed international Journal of Building Engineering.

The institute emphasized that the project aligns with its efforts to develop innovative scientific and technological solutions, enhance the utilization of local materials, and foster collaboration between the research and industrial sectors, thereby supporting sustainable development in the State of Kuwait.
