Pengaruh Fire Proofing pada Balok Beton Pasca Bakar
Abstract: Problem of
buildingfire, which is often happened, cannot be avoided. Burning that happened
generally reach temperature of above 200oC, what of course influence concrete
strength. Concrete material will become brittle, spelling, and barest easyto
and its strength is downhill effect of high temperature. In this research the
specimens are cylinder shape of concrete and reinforced concrete beams. For
this type of concrete cylinder specimens were made with size of 15 cm diameter
and 30 cm high, while for the typeof reinforcedconcrete beam specimens were
made with size of 15 cm x 20 cm x 150 cm. Each type of specimen for each
variety is made of 3 repetitions. Variations in temperature used are normal
temperatures, 400o C, 600o C and 800o C.The results of research show that the
use of fire proofing provide the value of concrete compressive strength better
than the concrete without fire proofing.The fire proofing increased the
compressive strength by 2.50%, 5.70% and 11.89% for temperature of 400o C, 600o
C and 800o C respectively. While the influence of fire proofing on the flexural
strength of reinforced concrete beams at the respective temperatures are 4.99%,
23.97% and 20.55%.
