What is it about?
Evaluation of the possibility of improving the adhesion between PP fibers and mineral matrices in cementitious composites by modifying the fibers’ surface with tannic acid. This modifier was previously used for PE fibers only. Cement mortar containing modified PP fibers and mortar containing unmodified fibers were tested. The physical and mechanical properties (apparent density, compressive strength, flexural strength and modulus of elasticity) were determined, and the fibers’ morphology after the specimens’ destruction was observed.

Why is it important?
The use of a fast tannic acid surface modification technique has not been performed on the polypropylene fibers for concrete before.
Perspectives
The results of research can be used for the industry purpose.
