Despite vigorous studies on ultra high-strength concrete in Korea, it still faces many challenges in application to on-site construction methods. This study intends to evaluate the applicability of the VH separated-pouring method which is currently used and was designed to pour ultra high-strength concrete with a design strength of 60, 100N/㎟ separately to girder and beam. When it comes to VH separated-pouring, there is a difference in the required design strength between a girder and a beam, which tends to be larger for ultra high-strength concrete. The tensile strength and cold joint at the joint end have not been commonly evaluated and thus the inevitably of its use is dependent on a structural analysis of the structural stress of reinforcement. In the study, potential problems with respect to the building material which might occur during the pouring of ultra high-strength concrete was evaluated and issues on joint surface performance, the hydration energy contained in the members, and the effects of contraction in concrete were considered as the key elements for study. |
