ABSORPSI AIR KOMPOSIT SEMEN SEKAM PADI DENGAN PENAMBAHAN POZZOLAN ABU SEKAM PADI DAN KAPUR PADA MATRIKS SEMEN
Abstract: This research aimed
to determine the role of rice husk ash as pozzolanic material in reducing water
absorption of rice husk cement composite. Rice husk ash obtained by burning
rice husk conventionally in kiln drum. Preparation of water absorption testing
samples was conducted according to ASTM C 140, while ASTM C 90 used to evaluate
the desired water absorption. Rice husk ash as of 40 % significantly reduced
water absorption of the composite, but only rice husk ash of 20 % dan 30 %
fulfilled the ASTM C 90 requirement. Addition of lime in the mixture increased
the water absorption.
