Abstract:

 Alum sludge is a by-product material produced from‟ water treatment plants that use aluminum salts as a primary coagulant, and is the most widely generated water treatment residual/sludge worldwide. Disposing this material has environmental impacts. Therefore, it is necessary to reuse this waste material in such a way, to reduce its adverse effects on the environment. This research studies the effect of alum sludge powder as partial replacement of Portland cement, on the fresh and mechanical properties of high strength concrete. In this study 60 concrete samples were prepared and subjected to compression, splitting tension and flexure tests. For compression test 7, 28, 90 day moist cured 100 mm cube specimens were used while for splitting tension and flexure tests 100* 200 mm cylinders and 100*100*500 mm beams moist cured for 28 days were used respectively. For this purpose concrete mixtures containing 5, 10, 15% alum sludge as a cement replacement, beside the control Portland cement mixture were prepared. The test results showed that despite the slight reduction in strength among the replacement of cement alum sludge, high strength concrete having 28 day compressive strengths up to 72 Mpa can be produced.
