PENGARUH PENAMBAHAN PASIR TERHADAP KUAT TEKAN DAN POROSITAS BETON POROUS
ABSTRACT: Porous concrete
consists of Portland cement, coarse aggregate, little or no fine aggregate,
admixtures, and water. Porous concrete
has high pore
volume, which results
lower compressive strength.
To increase the compressive strength of porous concrete
is done by add the sand into the mixture to reduce the pore volume to some
extent. Based on these issues,
the research on the
effect of the addition
of sand to the
compressive strength and porosity of porous concrete was done.
Cement-coarse aggregate weight
ratios used in
this study were
1: 5 and
1: 6, and
the water-cement ratios (wcr) were 0.3 and 0.4. Chemical
admixtures used are SicaCim Concrete Additive, with a dose 7.5 ml / kg of cement.
There were 3 specimens of each variation and the total of specimens were 36.
The samples used in this research
were concretes cylinder
150 mm x
300 mm. Compressive
strength and porosity
of porous concrete testing was
carried out after 28 days age.
From the results of this research, it can be concluded that the addition
of sand will decrease in slump value. Slump value of the mixture with water
cement ratio of 0.3 is smaller than 0.4, and cement-coarse aggregate ratio 1: 5
is greater than 1: 6. The addition of sand will increase in compressive
strength of porous concrete. Compressive
strength of porous
concrete with water
cement ratio of
0.3 is greater
than 0.4, and
cement-coarse aggregate ratio
1: 5 is
greater than 1:
6. The addition
of sand will
decrease porosity. Porosity
of porous concrete with water cement ratio 0.3 is greater than 0.4, and
cement-coarse aggregate ratio 1: 5 is smaller than 1: 6. The addition of sand
will increase density of porous concrete.
