Advancements in technology enhance not only human comforts but also damage the environment. Use of
steel fiber has become popular and safe now. Today the construction industry is in need of finding cost effective
materials for increasing the strength of concrete structures. Hence an attempt has been made in the present
investigations to study the behavior of fiber reinforced concrete in a composite material consisting of cement based
matrix with an ordered or random distribution of fiber which can be steel, nylon, polythene etc. The concrete incorporate
with steel fiber increases the properties of concrete, viz., flexural strength, compression strength, tensile strength and
shrinkage properties to name a few. This paper presents a detailed experimental study on fiber reinforced concrete at
age 28 days. The main variable investigated in this study is variation of bottle cap fiber dosage of 0.1%, 0.2%, 0.3%, and
0.4% by volume of concrete. Experimental investigation was done using C20, C25 and C30 mix and tests were carried
out as per recommended procedures by relevant Ethiopian & BIS codes. Test results indicate that the use of bottle caps
fiber in concrete has improved the strength of concrete. The study is conducted on a 1:1.5: 3 nominal concrete mixes,
with specimen sizes (150mm× 150mm × 150mm). The test results are compared for Compressive and split tensile
concrete strengths, with and without use of fibers.
