Studying the effects of alkali treatment on the properties of kenaf fiber for reinforced concrete elements

Kenaf fibers are coming into interest to use in reinforced concrete elements in recent years due to its attractive properties such as lightweight, non-abrasive, degradable, renewable and inexpensive. However, lack of good interfacial adhesion and high moisture absorption make the use of kenaf fiber...
