Pengaruh Abu Ampas Tebu Sebagai Bahan Tambah Terhadap Kuat Desak dan Kuat Lentur Serta Daya Serap Air Paving Block

Abstract

In an effort to reduce the cost of the building, one way is to use cheaper materials such as waste-disposal waste processing natural results. One of the waste that is bagasse which is a waste product of sugar manufacturing process. Utilization of bagasse to produce by burning bagasse ash. Bagasse ash content of the element itself has reached 70% silica that can be used as a pozzolan and as an alternative material added manufacturing paving block. With the added material bagasse ash is expected to improve the performance of block paving and can make a positive contribution towards waste utilization. The composition of the mixture used for paving block is 1pc: 6PS fas value 0.35 while bagasse ash as an ingredient added use from 0%, 2.5%, 5%, 7.5% and 10% of the weight of cement in the one variation. The process of making paving blocks made using hydraulic pressing machines and vibrator. Tests performed at age> 28 days after the process of the test specimen. From the test results obtained, each additional bagasse ash can increase the value of a strong and powerful urges flexibility on block paving, strongly urged the value of the highest average obtained in the addition of 10% bagasse ash in the amount of 306.07 kg/cm2 and the highest flexural strength addition of 10% bagasse ash in the amount of 31.19 kg/cm2. The more the addition of bagasse ash resulted in greater water absorption on the paving block. Water absorption value of the highest average in the addition of 10% bagasse ash is equal to 7.52%.
