CLSM flowable fill concrete product

This research project investigates the feasibility and performance of producing Controlled Low-Strength Material (CLSM) flowable fill using industrial waste streams, with red mud as the primary focus, complemented by blast furnace slag and bauxite residue. CLSM is a weak, flowable concrete-like material designed for non-structural applications such as backfill, trench filling, utility line bedding, and infrastructure repair, offering superior flowability and workability compared to conventional compacted fill. Red mud, a voluminous byproduct of aluminum oxide refining, presents significant environmental and disposal challenges globally, making its valorization in CLSM production particularly impactful for circular economy applications. The primary objective is to develop economically viable and environmentally sustainable CLSM formulations that incorporate red mud as the dominant waste constituent while meeting industry performance standards for strength (less than 1,200 psi), flowability, and workability.
