Pemanfaatan Limbah Plastik Polypropylene (Pp) Sebagai Bahan Baku Pembuatan Ecological Bricks Dengan Kalsium Karbonat Sebagai Admixture
ABSTRACT
The country of Indonesia is currently published as the second largest contributor
of plastic waste in the world, amounting to 28.4 thousand tons of plastic waste /
day. Plastic has caused problems in the environment and become waste that is
difficult to be reprocessed. Ecobricks (environmentally friendly brick) are made
from plastic waste so that it can reduce environmental pollution caused by
garbage so as to minimize the generation of plastic waste and prevent air from
arising from the process of making ecobricks without having to go through
surgery. This study discusses polypropylene (PP) glass packaging and refined
aggregate containing carbonate mixtures with a variation of 5%, 7% and on the
compressive strength and movement of concrete water according to PUBI, 1982.
From the results of the research, the highest compressive strength of the concrete
block with PP plastic mixture and 5% carbonate mixture at 28 days is 93 kg /
cm2 . Batako at the time of 28 days, the highest absorption of air (absorption)
occurred in a normal brick that is 14 66%.
Keywords: ecobricks, polypropylene (PP), calcium carbonate, compressive
strength, water absorption (absorption)
