Development of Mixing Model for High Durability Creek Concrete Having 300kgf/$\textrm{cm}^2$ Compressive Strength

압축강도 300kgf/$\textrm{cm}^2$ 내외의 하수암거용 고내구성 콘크리트 배합모텔 개발

Recently, we are facing with the trend of demanding high durability concrete for creek structures. When creek structures are deteriorated, it is very difficult to repair them. The objective of this paper is to develop a mixing model for high durability creek concrete having 300kg/$\textrm{cm}^2$ compressive strength. According to the result of durability experiment, high durability concrete for creek structures has high resistance of air permeability, absorption, chloride diffusion, and chemical attack.
