Perbandingan perilaku balok beton bertulang dengan menggunakan ordinary portland cement (OPC) dan portland composite cement (PCC)
Abstract: The development of
environmentally friendly knowledge emerging done and campaigned given the
severity of the effects of environmental damage caused by humans. One industry
that has contributed to the destruction of nature and the causes of global
warming is the effect of CO2 due to the cement industry. One way to overcome
this is to produce cement quality is maintained and environmentally friendly.
It is stated in the CDM (Clean Development Mechanism), which regulates the
development of more environmentally friendly with no prejudice to the functions
of the cement itself. Referring to the CDM, was made known by the Portland
Cement Composite Cement (PCC), where the mixture is not just made up of clinker
and gypsum alone, but it has been mixed with Pozolan materials such as fly ash.
PCC itself is still in the development stage, so it still needs a lot
more research on the use of this type of cement in the concrete mix. During
this new research conducted to investigate the compressive strength of concrete
using cement PCC. Therefore conducted this study aimed to determine the
compressive strength, flexural strength and crack pattern cement concrete using
PCC and compared with the behavior of flexural strength and fracture pattern
cement concrete using OPC.
Tests conducted in the laboratory based on ISO 03 - 2847- 2002. Covering
compressive strength test, flexural test and observation cracked reinforced
concrete beam pattern with a compressive strength of 25 MPa plan. The results
show that the compressive strength and the use of PCC up to the age of 28 days
is higher than the compressive strength of concrete with cement OPC. Crack
pattern that occurred showed a similar pattern, while the flexural strength of
concrete with cement OPC has higher flexural strength than concrete blocks with
cement PCC.
