Abstract
ABSTRACT
The study on bricks without combustion is needed to create an environmental friendly bricks, using coconut husk ash, clay and cement as an adhesive.
Study sites in BulotadaaBarat village, SipatanaSub-district. Materials used are a mixture of cement, clay and coconut husk ash, made four different samples with different mixtures in which 10% of cement and coconut husk ash (5%, 10% and 15%), clay, and water after was dried for 28 days and then coated with mortar and dried at room temperature for 2 weeks, ready to be compressive strength and water absorption test.
The results obtained, the physical volume shrinkage of 0%, 5%, 10% and 15% at 5.46%, 5.10%, 5% and 4.69% with the lowest volume shrinkage occurs in a mixture of 15% at 4.69% , while the compressive strength of the addition of coconut husk ash at 0%, 5%, 10% and 15% at 5.46%, 5.10%, 5% and 4.69%, where the highest compressive strength achieved in the percentage use of coconut husk ash at 5% amounted to 45.638 kg/cm2and water absorption of 0%, 5%, 10% and 15% at 15.505%, 13.456%, 14.686% and 16.014% with the lowestwater absorption at 5% as many as 13.456%.
Keywords: coconut husk ash, brick without combustion, compressive strength test, water absorption test
