Zusammenfassung: | Enormous amount of oyster-shell waste has been illegally disposed at oyster farm sites along the southern coast of Korea. To seek for a possibility to recycle the waste as construction materials, chemical and mechanical characteristics of crushed oyster-shell were investigated. Chemical and microstructure analyses showed that oyster-shells are predominantly composed of calcium carbonate with rare impurities. Compressive strength tests for soil mortar specimens with varying blending ratio of cement, water, sand, and oyster-shell were compared with normal cement mortar. There was no significant reduction in the compressive strength up to 40% of dosages of oyster-shell instead of sand. The experimental results demonstrate that oyster-shells can be resources of pure calcareous materials and effective in replacement of sand, indicating promising reusable construction materials |
