Opis

This research involves an experimental investigation into the improvement of bonding characteristics between a mixture of polyethylene/polypropylene fibers and concrete comparing various chemical and physical surface treatments and their effect on the mechanical properties of the fiber reinforced concrete (FRC). For the chemical surface treatment, several techniques of chemical etching of the fiber s surface were used, such as two types of chromic acid solutions, potassium permanganate, and hydrogen peroxide solutions. For the physical surface treatment, UV treatment and a combination of UV and Ozone treatment were used. Non-treated and treated fibers were added at 0.32% by volume and 0.50% for the best treatment method. Compressive, flexural strength and contact angle were measured to quantify bond improvement. Among the chemical treatment techniques, chromic acid solution type B was found to be the most efficient technique versus potassium permanganate which had negative effect on the bonding strength between fibers and concrete.
