COMMISSION INTERNATIONALE DES GRANDS BARRAGES ------- VINGT-SIXIÈME CONGRÈS DES GRANDS BARRAGES Autriche, juillet 2018 ------- INCREASE CONCRETE QUALITY IN DAM CONSTRUCTION DURING DESIGN AND EXECUTION PHASE Andreas ZITZENBACHER, Massimo MAFFEZZOLI, Stefan SCHEUCHELBAUER Doka GmbH AUSTRIA 1. INTRODUCTION The durability and service life of a dam structure is designed in an early stage of the planning phase. In order to achieve the planned target of concrete quality, monitoring during execution is one of the keys of quality management. For instance, in case of mass concrete structures one of the most important aspects is the monitoring of the temperature gradient and appropriate actions on site to avoid cracking and simply guarantee the concrete quality already during construction. The ambition is to emphasize the importance how to optimize the combination of formwork expertise with superior material technology enabling a well-defined construction sequence between all relevant parties. Resulting in increased quality management and enhanced durability of the designated concrete structure. 762
