Kuat Tekan Dan Kuat Tarik Belah Sebagai Nilai Estimasi Kekuatan Sisa Pada Beton Serat Kasa Aluminiumakibat Variasi Suhu
Abstract: This study was aimed
to determine influence of temperature variation to the compressive strength and
split cylinder strength of aluminium wire-mesh fibre concrete. Specimen was
concrete cylinder with 15 cm in diameter and 30 cm in high, and the volume
fraction of aluminium wire-mesh fibre was specified equal to 0.2%. Temperature
variations applied in this research were 25oC (room temperature), 400oC and
800oC. The result showed that increasing of temperature had caused compressive
strength reduction.Compressive strength at temperature 400oC and 800oC for both
normal concrete and wire-mesh fibre concrete were equal to 22.04%, 39.21%,
21.68% and 45.81%. Split cylinder test at temperature 400oC and 800oC for both
normal concrete and wire-mesh fibre concrete showed reduction which were equal
to 20.36%, 51.27%, 21.98% and 56.30%. On the other hand modulus of elasticity
reduction at temperature 400oC and 800oC for both normal concrete and wire-mesh
fibre concrete were 2.20%, 65.22%, 6.79% and 61.33%, where all of tests
werecompared to normal concrete and wire-mesh fibre concrete at room
temperature (25oC).
