Abstract

This study aims to investigate the properties of green concrete made with ground granulated blast-furnace slag (GGBS), Robo sand (RS), and coconut shell (CS). GGBS is the mineral admixture used to replace cement. Nano-silica particles (NSPs) and CS are used as coarse aggregates, and RS is the fine aggregate used to replace river sand. The workability, mechanical properties, and durability properties of green concrete are investigated and compared with those of conventional concrete (CC). Test results show that the cement replaced with 30% GGBS and 3% NSPs exhibits superior strength. The compressive and splitting tensile strengths are increased by 24.03% and 42.32% after 28 days of curing, respectively. The workability is improved by 12.22% (slump) and 13.25% (compaction factor) after 28 days of curing. The sorptivity of HM3 (3.26%) is lower than that of CC due to the uniform distribution between particles. Microstructure evolution is carried out to identify concrete mix behavior.
