Kuat Tekan Dan Sifat Fisik Beton Opc Dan Opc-Rha Untuk Aplikasi Di Lingkungan Gambut

The aggressive environment, especially the peat environment contains many
chemicals that can unravel the elements in the concrete, causing damage to the
concrete. This study examines the strength and physical properties of OPC
(Ordinary Portland Cement) concrete and OPC RHA (Rice Husk Ash) concrete
exposed in peat environments. RHA as one of pozzolan with high silica is used as
a replacement of cement with the substitution of 5% and 10%. This concrete is
tested mechanically and physically such as compressive strength, porosity, and
permeability tests after soaking in peat canals for 7, 28, and 91 days, in addition
to fresh concrete tests such as setting time and workability. The concrete strength
of the planned concrete is K-250. The peat water used as a test immersion
medium has a pH of 3.5-4.5. The results of fresh concrete testing show that the
addition of RHA makes the workability decreases and the setting time becomes
longer. The lowest workability and the longest setting time were obtained from a
mix containing 10% RHA. The compressive strength of OPC concrete drops to
1,18% at 91 days. In contrast to OPC concrete, the compressive strength of OPC
RHA 5% and OPC RHA 10% continued to increase respectively 10,77% and
37,15% until the age of 91 days. The 10% OPC RHA concrete has the highest
compressive strength of 23,00 MPa. Porosity and permeability of OPC RHA
concrete decreased with increase in curing time. The lowest porosity and
permeability are shown by OPC RHA 10% concrete. Based on the results of the
test, it is concluded that the replacement of cement by RHA, has a positive effect
on all physical properties of concrete to exposed to peat environtment.
