The present academic paper analyzed a
general approach of compressive strength
and rigidity behavior, through of modulus
of elasticity and Poisson’s ratio of a
concrete. Variables utilized were
polypropylene reinforcement in
percentages corresponding to 0.30 % and
0.50% of cement weight; as well as
laboratory furnace exposure, with the aim to
emulate the increase of the temperature that
happens progressively during a fire, using
different temperatures (room temperature,
130°C and 180°C). In order to obtain this
data, standard cylinders were manufactured
for further testing.
From obtained results was concluded that
the optimum percentage of polypropylene
fiber considering the exposure to high
temperatures was 0.50%, since it reported a
significant increase in compressive
strength, which would mean the
preservation of the supposed structure in
case of being exposed to a fire. Besides, the
mechanical properties that trigger
concrete´s rigidity showed results of
modulus of elasticity close to those
established by regulations, and Poisson’
ratio values obtained were close to those
established in the bibliography. |
