| As a result of compressive strength, specimens having mixture rate of cockle shells of $15%;and;20%$ showed more increases of compressive strength than non-mixture specimens as age increases. Ductility capacity of specimens was higher in specimens mixing cockle shells than in specimens using general fine aggregates and specimen of $10%$ of cockle shells was highest in ductility capacity. To sum up all experimental results, ductility capacity of specimen without shear reinforcement using mixture of cockle shell was higher than non-mixture specimen and it is considered that mixture of cockle shells up to $20%$ as fine aggregate for concrete will be available. Continuous researches on durability, workability and economy of crushed cockle shells used for substitute fine aggregate of concrete will be needed. |
