PENGARUH SEMEN OPC DAN PCC TERHADAP KUAT TEKAN DAN KUAT LENTUR PADA BETON MUTU TINGGI FAKTOR AIR SEMEN 0,36 DAN 0,39
ABSTRACT: This study used an
experimental method in the Laboratory of Structural and Construction Engineering
Faculty, University of Lampung. The test object in this research is a concrete
cylinder with a diameter of 15 cm and 30 cm high. And the concrete beam
specimen with a length of 60 cm, width 15 cm, height 15 cm. While testing the compressive
strength and flexural strength of high strength concrete made fas 0.36 and 0.39
after the test specimen was 14, 28 and 56 days. In testing the compressive
strength of concrete fas 0.36 and 0.39, OPC cement concrete without silica fume
replacement compressive strength higher than the compressive strength of cement
PCC. Value OPC cement with fas 0.36 and 0.39 in the concrete life of 56 days
each -masing amounted to 39.7264 and 34.9139 MPa. OPC concrete of cement with
silica fume replacement of 10% in testing concrete compressive strength fas
0.36 and 0.39, higher compressive strength of cement PCC. The compressive
strength of OPC cement with silica fume replacement fas 10% with 0.36 and 0.39 in
the concrete life of 56 days each for 33,7816MPa and 30,9507MPa. In the
flexural strength testing of concrete fas 0.36 and 0.39, OPC cement concrete
without silica fume penggntian strong bending higher than cement PCC. OPC
cement flexural strength values with fas 0.36 and 0.39 in the concrete life of
56 days each for 7,3778MPa and 7,6MPa. OPC cement concrete with the replacement
of silica fume 10% in flexural strength testing of concrete fas 0.36 and 0.39,
a strong bending higher than cement PCC. Flexural strength value of OPC cement
with silica fume replacement fas 10% with 0.36 and 0.39 in the concrete life of
56 days each for 7,8889MPa and 8,3333MPa.
