Abstract

Concrete is most widely used material in the construction as it is relatively strong in compression but weak in tension and tends to be brittle. These two weaknesses have limited its use. Fiber reinforced concrete is most widely used for improving tensile and flexural strength of concrete. In this paper an attempt has been made to explore the effects of polypropylene fiber on some hardened properties of PFRC based on its compressive strength, flexural strength and flow ability. In this research, concrete mixes were added with polypropylene fiber of 0%, 0.2%, 0.4%, and 0.8% volume fraction and Steel Fibers were added in a varying dose of 0%, 0.2%, 0.4%, and 0.8%. An experimental result demonstrated a notable increase in flexural, tensile strength was found. However, no significant change in compression strength is observed.
