Compressive strength of concrete with fibres at elevated temperature

Concrete, when exposed to high temperature, can cause spalling, cracking,
and severe damage, which could lead to a sudden collapse of a building. One
of the solutions for overcoming this weakness of concrete is by incorporating
fibres in the concrete mix. Concrete incorporated with more than one type of
fibres is often known as hybrid concrete. In this paper, the compressive strength
of the hybrid concrete when exposed to elevated temperature is studied. The
result is compared to concrete mixed with a single type of fibre of polypropylene
or steel fibres. An observation of spalling is also carried out to verify the
compressive strength test. The test results showed that both the single fibre
specimens with steel fibre and hybrid specimen improved by 23.34% and 24.60%
in residual strength compared with other residual strengths of concrete
specimens.
