Abstract :
In this modern era, the construction of buildings in large cities is growing so rapidly. This results in the need for building materials such as gravel, sand, and cement will also increase. The building consists of roofs, walls, and floors. material commonly used in the manufacture of walls of concrete brick, brick, and brick. This research was conducted by using residual ash of garbage burning and fly ash as innovation of mixed material of solid brick making and as effort of waste utilization. In this research, it is done with two stages: material testing and making of test specimens with mixed cake mix of 0% (normal brick), 10% fly ash, 5% ash + 10% fly ash, 10% ash + 10% fly ash, 15 % ash + 10% fly ash which conducted compressive strength test and water absorption at 7 days, 14 days and 28 days. At the age of 28 days, the highest compressive strength was found in the variation of 10% fly ash mixture of 77.50 kg / cm ² and entered the quality level II with water absorption of 8.99%, while the lowest compressive strength was found in mixed variation 15% ash + 10% fly ash was 37.92 kg / cm2 and entered the quality level II with 11.21% water absorption.
