Abstract

The effects of the chemical surface treatment of polypropylene fibres on the compressive strength of polypropylene fibre reinforced concrete was investigated. A 3500 psi concrete design mix with Portland Type 1 cement was utilised as the base-composite and control group. The chemical solutions used to treat the polypropylene fibre (PPF) surfaces were a basic solution and a mild organic acid. The PPF as well as the chemically treated PPF were utilised in the preparation of the fibre reinforced concrete samples. The compressive strengths of the concrete samples were tested according to ASTM 4.02, C-39 procedures. The failed surfaces of the PPF were prepared and analysed using the scanning electron microscope (SEM). Interfacial characteristics of the fibre surfaces and the hydration crystalline products were evaluated prior to and after the chemical treatment. A correlation between the microstructural analysis, chemical surface treatment of the PPF, and the compressive strength of the reinforced composite is reported. © 1987.
