UTILIZATION OF WASTE MATERIALS IN MANUFACTURING OF CONSTRUCTION PRODUCTS
This research was to investigate the possibility to use paper sludge and palm oil fuel ash (POFA) in manufacturing of construction product. 60 cubes were tested to determine the compressive strength of mixes with different mix proportions. The optimum water/sludge ratio and high-range water-reducer admixture percentage were also determined. Mix with suitable compressive strength was chosen to carry out the water absorption test. Study shows that paper sludge and palm oil fuel ash mix with cement can be used to make brick that comply strength requirement of BS 6073.
