A Study on the Properties of High Early Strength & Durability of Concrete using PC Admixture

PC계 혼화제 사용 콘크리트의 조강특성 및 내구특성에 대한 연구

This study reports the properties of high early strength & durability of concrete using PC admixture. To apply these data to construction site, we did the lab tests. The target of this study is to accomplish early strength of concrete(5.0 MPa/18 hr), and we did the durability tests such as length change test, chloride ion penetration test, adiabatic test, etc. PC type was more excellent than PNS type admixture. According to these tests, we concluded that we can apply this type of PC admixture to the civil & construction site, and we can reduce the term of works and finally we can accomplish the economical construction.
