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

This study reports the properties of high early strength of concrete using PC admixture. To apply these data to construction site, we did the lab tests and mock-up test. The target of this study is to accomplish early strength of concrete(5 MPa/18 hr), and we tested 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. 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.
