Treatments on Polypropylene Macro Synthetic Fibers for Improving Adhesion in Structural Concrete Reinforcement: A Systematic Review

Journal of Applied Polymer Science, EarlyView.
Surface functionalization of polypropylene macrofibers to enhance fiber‐matrix interfacial bonding. ABSTRACT Concrete is the most used higher compressive strength‐building material, albeit brittle to tensile, and flexural loads. Polypropylene (PP) synthetic polymeric macrofibres are commonly employed as reinforcement material to prevent this situation ...

Influence of sizing of basalt fiber on the mechanical behavior of basalt fiber reinforced concrete

Journal of Materials Research and Technology, 2022
In this study, the original basalt fiber (BF), and the sizing-removed BF through the heat treatment were pneumatically dispersed by using an air compressor and then were added into normal strength concrete to produce BF reinforced concrete (BFRC). The compressive test, splitting tensile test, and flexural test of BFRC specimens with two types of BF ...
