What is Cockle Shell as Concrete Aggregate Replacement about?

1) The study investigated using cockle shell as a partial replacement for coarse aggregates in concrete at levels between 5-30%. 2) Results showed that replacing 20% of coarse aggregates with cockle shell produced workable concrete with the highest compressive strength compared to other replacement levels. 3) Both workability and strength were reduced at higher replacement levels (over 20%) due to the rougher texture and irregular shape of cockle shells increasing friction and requiring more cement paste
