Abstract:
Today many countries are producing self compacting concrete (SCC)
and it is known that SCC has many advantages compared to conventional concrete.
In order to improve tensile strength of concrete steel fibers can be added in
concrete. Although fiber reinforced concrete (FRC) is being produced in Cyprus
for a long time, SCC is a new product for construction industry. Therefore,
combination of SCC & FRC would bring many benefits.
This study was split into 3 parts. First part was based on the design of FRC 2
different fibers namely steel and polymer. Second part was based on designing
SCC with locally available materials of Cyprus in addition to chemical additives.
The third part was based on combination of SCC and FRC. Produced self
compacting fiber reinforced concrete (SCFRC) was tested for fresh mix properties
such as flow spread, T50, L-box, V-funnel, and hardened properties such as
compressive strength, splitting tensile strength and permeability. The results have
shown that the addition of fibers improve hardened properties. It has also been
found that better workability can be obtained for SCFRC by adjusting w/c ratio and
admixture.
