Abstract

The construction industry's ongoing quest for sustainable materials has directed attention toward the use of industrial by-products and natural pozzolans as alternatives to conventional cement. This study explores the combined effect of lime sludge and metakaolin, introduced as equal-proportion partial replacements for cement, on the fresh and hardened properties of M30 grade concrete. Replacement levels of 0%, 10%, 20%, and 30% were considered, designated as LM(0), LM(5), LM(10), and LM(15), respectively. Experimental evaluations included compressive strength, split tensile strength, flexural performance, and slump retention, conducted at multiple curing intervals up to 90 days. Results demonstrated that a 20% total replacement (LM10) yielded the most favorable outcomes, surpassing the control mix in all mechanical parameters. The enhanced performance was attributed to the fine particle size and high pozzolanic reactivity of metakaolin, complemented by the filler effect and latent hydraulic behavior of lime sludge. Notably, the LM(10) mix exhibited superior strength development without compromising structural reliability, making it suitable for both load-bearing and durability-critical applications.
