Indian Concrete Journal - ICJSummary: The proper disposal of the wastes generated from the industries is a severe concern in India. The byproducts from industrial waste are used for many civil engineering applications. Amongst them the usage of common effluent treatment plant (CETP) sludge for development of controlled low-wtrength materials (CLSM) is still to be explored. The CLSM or flow-able fill could be used effectively as alternate in preserving or limiting the usage of construction materials. They are used in the areas, where compaction equipments are not feasible. The study aims to investigate fresh and hardened properties of CLSM (constituting proportion of class-F fly ash, CETP sludge, cement, M-sand and water). The work carried facilitate in developing eco-friendly CLSM mix in which byproduct material utilization is maximized, satisfying workability and performance requirements. The developed CLSM constitute for three levels of cement substitution with CETP sludge (i.e. 5, 10, and 15 %) for five classes of mix design (A, B, C, D, and E). The outcome of the results was promising and found that the flowability values were between 20-25 cm and unconfined compressive strength (UCS) was found maximum for Mix E at 28 days. Based on the UCS results, the CLSM developed may be considered for the possible application in pavement bases or for permanent fills.
