Behavior of concrete with saw dust in different curing method

Abstract

This proposal is intended to study the behavior of concrete with saw dust with different curing method like water tank, plastic, box and wet gunny. The proportioned mixture uses are cement, sand, aggregate, water and saw dust. The ratio of saw dust selected to use to replace several amount of sand in the concrete are 10% respectively. Three types of testing were conducted to get the result are slump test, compressive strength and water absorption. The average result for the slump test is medium which is in between 50 – 100 mm. The result for compression strength for normal concrete, the highest value is on 28 days curing in the boxes for 39.78 MPa. For the result for compression strength for addition 10% of saw dust in the concrete, the highest value is on curing in gunny for 14 days and the value is 33.86 MPa. As the conclusion, the best curing by using gunny is the best method to curing the concrete contain 10% of saw dust.
