Pengaruh Penambahan Abu Serbuk Kayu terhadap Kuat Tekan Beton

Abstract

Concrete is a material that is widely used and become the main element in the building. The advantages of concrete, among others, have a strong high pressure than the tensile strength, easy to form, does not require special care, the material is easy to obtain from the surrounding, and more durable than other building materials. The more concrete is used as a constituent material of the concrete, it encourages research to develop the material as well as the way of making concrete. Sawmill sawdust is one type of wood particles whose weight is very light in dry and easily flown by the wind. Where the wood powder itself is known as industrial waste furniture that many buried and tend to become garbage because its utilization is still little or relatively small, so need to be handled seriously. In addition, today sawdust is only used for a small portion of the need only. The purpose of this research is to find out the compressive strength of concrete and to utilize the ash waste of wood as a 10%, 20% and 50% concrete additive with the planned concrete quality of K250, with 28 days concrete plan, Added wood dust on mix Concrete leads to a decrease in the compressive strength of normal concrete in each percentage percentage. This is because the mixture of Ash wood powder absorbs much water, thus causing the cement binding to the aggregate is reduced, resulting in a decrease in the compressive strength of the concrete
