The Substitution Effect of The Fine Aggregate in Concrete with Oyster Shell

Materials
The construction industry is responsible for around 27% of carbon emissions. Concrete raw materials consist of cement, Coarse Aggregates, Fine Aggregates, and admixtures. In this study, Oyster shell powder produced by Taiwan Sugar Company replaced fine aggregates in different proportions to test the strength of concrete. The proportion of concrete used
