Karakterisasi Batu Bata dengan Campuran Abu Sekam Padi

Abstract

Have been done a research of bricks made clay with a mixture of dusty luced up paddy printed by compaction, drying, and baked at a temperature of 8000 C. After age 7 days, testing the characteristics of mechanical properties and physical properties test objects such as; compressive strength, bending strength, porosity and fired shrinkage . The bricks are made with varying mixtures 0%, 5%, 10%, 15%, 20% and 25% dusty luced up paddy to clay. The result of analysis obtained that value of compressive strength 5,68 MPa – 10,97 MPa , bending strength 0,53 MPa – 3,08 MPa, porosity 27,98% - 34,67% and fired shrinkage 0,34% - 1,72%. This result show that bricks can be made dusty luced up paddy with mixtures 5% - 20%.
