Large base slabs in the industry are exposed to different types of loading. In many cases, the restraint to imposed deformations due to temperature and shrinkage is decisive for the design. The most common loads for base slabs are introduced. In order to rationalize the fabrication of large slabs, a new concept for base slabs made of textile reinforced self-consolidating concrete (SCC) is presented. The advantages of textile reinforcement compared to ordinary steel reinforcement are pointed out. The main objective is to limit the crack width and to avoid expansion joints. Therefore, numerous tensile tests with differently prepared carbon rovings have been performed in order to analyze and advance the bond behavior of carbon reinforcement in SCC. These rovings serve as the basis for a technical textile as reinforcement for large base slabs.
