Abstract
In light of the fact that natural fibers are used, since many centuries for different purpose at the
beginning of civilization. They have been used for ropes, toughening of pots etc. Considering
global environmental warming problems, research and innovation in natural fiber reinforced
concrete has been rising rapidly at present. Interest is warranted due to the advantage of natural
fiber compared to others, such as synthetic fiber, which includes low environmental impact and
low cost and support their potential across a wide range of applications.
Natural fibers are categorized in to two. Those are natural inorganic fibers like carbon Asbestos
and so on and the other are the natural organic fibers likes coconut, palm, kenaf, jute, sisal,
Enset, pine, sugarcane, bamboo etc. The natural fibers are investigated by a lot of particular
researchers as construction materials that could be used in cement paste/mortar/concrete. Much
effort has long been made to improve their mechanical performance in order to expand fiber
capacities and applications. The present work is carried out to evaluate the compressive, tensile
as well as flexural strength of concrete using enset fibers.
Fiber length is the essential factor that influences the properties of fiber reinforced concrete.
Hence the prediction of effective fiber length becomes important. Results on compressive
strength, split tensile strength and flexural strength of concrete samples for quite a number of
combinations are analyzed with the use of different fiber length. Fibers used with length of
10mm, 15mm and 20mm with constant percentage of 1.5% by weight had been used for the
work. Natural fiber reinforced concrete is suitable for low-cost construction, which is very
desirable for developing countries. Normal C -20 mixes was used for the study. It is observed
that enset fiber length can affect significantly the mechanical properties of concrete.
