BATAKO LUMPUR LAPINDO SEBAGAI ALTERNATIF MATERIAL PASANGAN DINDING
Abstract: Block made of mud is
a building material used in making wall for building that is made from sand,
cement, and fly ash using certain percentage mud in sand. This research aimed
to know the effect of the use of lapindo mud towards the compressive strength,
the absorption of block water with the mud dosage in sand are: 0%, 10%, 20%,
30%, and 40%. This research was an experimental research; each design was made
in size 10x20x40 cm using 5% of fly ash and without fly ash. The result of this
research showed that the highest compressive strength was raised in 10% mud in
sand with 5% fly ash that was 195 kg/cm2 or increased about 3.44 kg/cm2 within
increasing percentage about 10.651% towards the compressive of block without
lapindo mud with 5% of fly ash, and was included in class I quality of block.
While for the 30% and 40% mud percentage is lower compared with normal
compressive strength of block. The test result of water absorption of lapindo
mud block showed the higher value than 20% for lapindo mud block with 5% fly
ash, in framing the mud blocks as the wall, those blocks need to be soaked
first because the absorption value of block is higher than 20%. Lapindo mud
block without 5% fly ash has bricks water absorption less than 20%, while in
framing those bricks, they don’t need to be soaked because the absorption of
brick if lower than 20%. By using fly ash in mud block, we can get the higher
compressive strength and the lower water absorption.
