To address land occupation and environmental pollution from mine tailings (MTL)
accumulation, MTL has been used as a replacement for cement or fine aggregate in concrete production.
This study focused on producing self-compacting concrete (SCC) by substituting MTL for an equal mass
of GGBS, offering a sustainable way to incorporate MTL into SCC. The research investigated the effects
of replacing GGBS with MTL on both the fresh and hardened properties of SCC, evaluating parameters
such as slump value, drying shrinkage, compressive strength (CS), and split tensile strength. Results showed
that adding MTL impacted workability and performance. While 50% MTL reduced workability initially, it
still met standard requirements. Early drying shrinkage increased with higher MTL content but remained
manageable at 25% substitution. Compressive strength improved significantly at one, three, and seven days
with MTL, stabilizing at 28 days with a 2.86% increase in CS.
