Extending 3D concrete printing to hard rock tunnel linings : adhesion of fresh cementitious materials for different surface inclinations Universiteit Gent
As an emerging automated construction technology, 3D concrete printing opens the opportunity for the construction of hard rock tunnel linings. However, very limited studies were carried out in this regard, especially the adhesion between freshly printed cementitious materials and the excavated rock wall deserves further attention. In this study, the adhesive performance of the fresh cementitious material at two representative surface ...
