| Abstract |
Recently, the buildings in urban area is becoming super-tall for using the land in efficient way and obtaining the good sight view. According to the progress, the structural members are more massive than the past in order to insuring structural safety. Among those members, the mat foundation requires tremendous amount of concrete. Moreover, it is very hard to install the construction equipment in the construction site where is highly densified. The reason of the difficulties of the equipment installation, the structures can not be integrated or occurred the construction joint, even the concrete casting is delayed. Therefore in the paper, it is aimed to evaluate the on-site application of the setting time lagging method for mat foundation-mass concrete by introducing super retarder concrete. In addition, the availability of the method was identified by analyzing the result of on site application. |
