A Study and Evaluation of Super High Early Strength Concrete as Pavement Overlay Materials for Early Traffic Opening(3)
신속개방형 콘크리트 도로포장재의 설계를 위한 평가 연구(3)
Abstract
In road pavements, it is known that cement concrete pavement has superior durability, safety compared. But in repairing pavement, cement concrete pavement is not usually applied because of the length of time while the road is interrupted when using Ordinary and Rapid-hardening Portland Cement. And Super High Early Strength Cement and Ultra Super High Early Strength Cement are not favorable for ready mixed concrete because of rapid setting time, high slump loss and other restrictions. We developed special cement developing 1 day strength of over 30.0N/mm
