Abstract

In this study, Controlled Low Strength Material (CLSM) specimens were fabricated from the mixture of cement, fly ash and sludge. The sludge is non-toxic and its heavy metal composition is very low. In this study, flowability of CLSM was investigated. Four cases were tested with varying amount of sludge and cement, mixed, and then tested using the flowability test. Results showed that CLSM with higher amount of sludge is less flowable. It is important for controlled low strength material to maintain its low strength. This study also aimed to determine the compressive strength of mixtures of CLSM from cement, fly ash and sludge. CLSM specimens were cured for 28 days and were then subjected to compressive strength testing. It was found out that the 23% mixture cannot be categorized as low strength material since it did not pass the required maximum strength and CLSM containing 35% or higher had the strength which is lower than the required compressive strength.
