| Abstract |
The research pursues to establish foundation to manufacture concrete for water tanks and channels to improve water quality; the purpose is to set mixture ratio according to various replacement rate for carbon absorbent, to analyze physical property of concrete, and to seek methods to apply concrete in an environment-friendly manner. The result showed that in case of fresh concrete, as the replacement rate for carbon absorbent increased, air volume and slump declined, while the amount of bleeding increased. Regarding hardened concrete, as the replacement rate for carbon absorbent increased, compressive and tensile strength, and change of length decreased, while the absorptivity increased. In evaluating water quality, the amount of floating material and heavy metals Cu-, Cd- decreased by 20～40% with increasing replacement rate for carbon absorbent. |
