The Effect of Using Sawdust as Mixture of Concrete Pipe on Water Absorption and Compressive Strength

Abstract

This article describes an experimental study of the effect of using sawdust as a mixture of concrete pipe on water absorption and compressive strength. This research was inspired by the amount of sawdust waste from sawmills that had not been utilized. For this purpose, 18 specimens were made with four different values for sawdust: iron ore (5%, 10%, 15%, and 20%). Each specimen has the composition of cement: iron ore (1: 4), and water: cement (0.5%). This research was conducted at PT Indal Steel Pipe. This research to analyse the effect of using sawdust as a mixture of concrete pipe on water absorption and compressive strength. Experimental method using compression test and water absorption test has been used to this study. Main finding from this study showed the higher the composition of sawdust increased water absorption and reduced the compressive strength of the concrete pipe. This study will be useful to reduce waste pollution and improved concrete pipe material in term of production cost.
