PENGARUH PEMAKAIAN LIMBAH GENTENG BETON TERHADAP MUTU BETON SEDANG
Abstract: In line with the
economical development, there are a lot of old buildings renovation which
produces material waste like roof tile.To use the existing roof tile waste, the
research on the use of cncrete roof tile waste for concrete mixture was
performed considering that concrete roof tele fraction is hard enough. By using
part of concrete roof tile fraction in the agregate for concrete mixture, it is
expected that it doesn’t affect the quality or pressure strength of produced
concrete. This is more economical since the pebble price is more expensive than
concrete roof tile price. The aim of the reseach is to find out the percentage
of concrete roof tile fraction in the coarse aggregate for concrete mixture so
that it doesn’t affect the concrete pressure strenght, seek for the correlation
between concrete pressure strenght and the precentage of concrete roof tile
fraction in coarse aggregate for concrete mixture, seek for the correlation
between concrete pressure strenght and aggregate weathering. In the research,
the testing material is in the form of cube 15 x 15 x 15 cm with slump value as
the fixed variable mean while the non fixed variable is the precentage of
concrete roof tile fraction in the mixture, that is 0, 10, 20, 30, 40, 50 % of
is coarse aggregate. From the result of the research, it is obtained that in
the 10 % percentage of concrete roof tile fraction, the generated concrete
pressure strength doesn’t change or has no influence. The correlation between
concrete pressure strength and the percentage of concrete roof tile fraction in
the aggregate is y = -1.539 x + 242.6 and the correlation between concrete
pressure strength and the aggregate weathering is y = -6.519 x2 + 242.2 x –
2013. With the percentage ot roof tile fraction in the aggregate asmuch as 50 %
may affects the decreasing of concrete quality and the concrete pressure
strength reaches 29.5%.
