Abstract:
High performance concrete (HPC) is one of
the prevailing techniques which have become popular due
to its mechanical and durability properties. To enhance
the property, fibre reinforcement is providing with
steel fibre and also overcome the insufficient curing
problem due to human irregularity during the period of
curing the self curing methodology have been adopted. In
this study mechanical property of self curing HPFRC is
examined with varies percentage of self curing agent of
Polyethylene Glycol (PEG400) with a constant proportion
of silica fume and steel fibre. The steel fibre of
aspect ratio 50mm is adopted for minimizing the cracks
in concrete and improving strength, durability, impact,
toughness etc. The HPC of grade M60 is prepared with
water cement ratio of 0.3 and PEG400 varies from 0% to
1.5% at 0.5% intervals with and without using steel
fibres and replacing cement with 6% of silica fume. To
enhance the workability of HPC, super plasticizer
(conplast 430) at a range of 1.8% of cement was used.
Mechanical properties like compressive strength, split
tensile strength, flexural strength and modulus of
elasticity were examined at 3 days, 7 days and 28 days
to evaluate the optimum percentage of PEG 400 with and
without steel fibre.
