STUDI PENGARUH TIGA METODE PEMADATAN BETON SEGAR TERHADAP KUAT TEKAN DAN SEGREGASI BETON DENGAN MUTU BETON K-300 (fc’=24,9 MPa)
ABSTRACT: Compaction of fresh
concrete is one of the processes in the concrete casting that has a significant
effect on the strength of concrete as final result of the casting. The research
conducted under the use of the Indonesian National Standard (SNI) and the
American Society of Civil Engineers (ASCE) is aimed to determine which of the
compaction methods is more effective in terms of compressive strength and the
effect of segregation. The results shows that the fresh concrete compacted by
using standard compactor achieved the highest strength value of 115.23% for
7-day-maintained concrete samples and 124.25% for the 28-day-maintained
concrete samples. While samples compacted using modified compactor achieved
average value of 112.39% for 7-day-maintained samples and concrete 117.57% for
28-day-maintained samples. Concrete compaction using native rod achieve the
lowest compressive strength of 108.70% for 7-day-maintained samples and 117.12%
for 28-day-maintained samples. Neither of each methods show any signs of
concrete segregation.
