Abstract |
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. Thetarget 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, freezing and thawing test, adiabatic test, etc. And we tested the porperties of concrete by the different factors, such as the type of admixtures, curing temperature, the amount of binder, etc. Through the test of concrete using the different type of admixture, PC type was more excellent than PNS type admixture. As a result, we made a concrete of high early strength concrete, and excellent durable concrete. 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 will accomplish the economical construction.
