• Abstract:
  This study explores the use of agricultural bio-waste such as eggshell powder and sugarcane bagasse ash (SCBA) as sustainable alternatives to cement production. Eggshell powder was evaluated as partial substitutes for limestone filler with and without heat treatment. SCBA, a silica-rich byproduct of sugar production, was investigated for its potential as a supplementary cementitious material (SCM) akin to Class F fly ash. Experimental methods included material characterization using SEM, XRD, XRF, TGA, and LOI testing, as well as evaluations of fresh and hardened concrete properties. Results demonstrated that treated eggshell and SCBA samples exhibited favorable morphological and chemical properties for use in blended cement systems. Eggshell powder can be used as an alternative to limestone at lower proportions of inclusion; However, heat treatment is recommended to denature the organic content from eggshell membrane at high proportion of inclusion. Meanwhile, SCBA is a pozzolanic material that can be blended with cement for optimal strength and durability. The findings support the feasibility of incorporating bio-waste into concrete formulations, contributing to sustainability efforts in construction and transportation infrastructure.
