BEHAVIOR OF CONCRETE WITH POLYVINYL ALCOHOL (PVA) FIBERS

Concrete possessed characteristics whereby it has high strength in compression
but weak in tension. In order to mend this disadvantage of concrete, Polyvinyl Alcohol
(PVA) fibers are infused in concrete mix. It is considered as one of the most suitable
polymeric fibers to be used as the reinforcement of concrete due to its advantages such as
it will never rust, having high bond strength with concrete or mortar, having high
modulus of elasticity etc.
Along the project period, properties of PVA fibers were studied as well as some
other fibers commonly used in concrete technology. The characteristics of PVA fibers
and concrete were also investigated in order to determine the ideality of mixing them
together and what the significant impacts are, This project focuses on the properties of
hardened PVA fiber reinforced concrete. In order to determine that, all concrete samples
w1,1re tested for their compression and flexural strength. From the result obtained, it can
be concluded that PVA fibers improved characteristics of concrete in terms of its
strength.
