Field Application of High Strength Concrete under Cold Weather Conditions

650kgf/$\textrm{cm}^2$ 고강도 콘크리트 한중 시공사례

High strength concrete(65MPa) was used for construction of the bulk cement storage silo by using sliding form. This paper presents mix design, production, quality control and experience with field application of high strength concrete under cold weather conditions. It is shown to be possible to produce high strength concrete of compressive strength of 50~60 MPa by using high-range water reducer to lower w/c ratio with appropriate quality control.
