Portland cement mortar reinforced with polypropylene wires for thin-walled concerte units
The non-metallic reinforcement has a great interest in concrete elements because this type of reinforcement is not subject to corrosion as the steel reinforcement. This fact is particularly important in the case of thin-walled elements due to small cover of reinforcement. The non-metallic reinforcement in thin-walled elements has been already investigated Meshes of more resistant materials, as glass, carbon, aramid, PVA, or polyethylene fibres have been studied in spite of the polypropylene presenting lower strength and lower elastic modulus than other previously mentioned materials, it has interest in situations where it is not necessary high strength reinforcement, and only mortar tension strength is enough. This paper presents results of bending and tension tests of cement mortar reinforced with polypropylene wires. The results show that polypropylene wires could work as a safety against the fragile rupture. In order to achieve this behaviour, it is recommended 1 % of polypropylene wires in volume for mortar of 30 MPa or less compression strength.
