Abstract

Abstract
This study explores the development of a coconut shell concrete (CSC) mix design using the
ACI211.298 guidelines, targeting a compressive strength of 20 MPa for structural applications. Due
to the organic and flaky properties of coconut shell (CS), achieving the initial target strength of 40
MPa was challenging, necessitating a focus on optimizing mix proportions for a 20 MPa goal. The
research investigates three different mixes with varying percentages of ground granulated blast
furnace slag (GGBFS) (0%, 25%, and 50%) while adjusting the water-to-binder ratio (w/b) and the
coarse-to-fine aggregate ratio (C/F). The compressive strength performance of each mix was
evaluated under three curing methods: water curing, steam curing, and conceal curing over 7 and 28
days. Results indicate that Mix1 (0% GGBFS) achieved the highest strength of 30.1 N/mm² under
conceal curing, while Mix3 (50% GGBFS) displayed the lowest gains. Conceal curing consistently
produced superior long-term strengths across all mixes, while steam curing favored early strength
gains but lagged in later stages. The findings demonstrate the influence of GGBFS content and curing
methods on CSC’s performance, offering insights into sustainable concrete solutions using alternative
materials.
