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 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%). The research was conducted at PT. Indal Steel Pipe. This reaserach to analyze the effect of using sawdust as a mixture of concrete pipe on wtaer absorption and compressive strength. Experimental methode using compression test and water absorption test has been usedto 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.
