Dauerhaftigkeitspotentiale selbstverdichtender Betone

The Potential Durability of Self‐Compacting Concrete Owing to its exceptional fresh concrete properties, the use of self‐compacting concrete SCC offers numerous technological and economical advantages. However, during the planning of constructions the question arises as to whether the special composition of SCC affects durability. Thus the potential durability of different SCC compositions was investigated systematically at the Centre for Building Materials (cbm) of the Technical University of Munich. In a first series of tests, attention was focused on the effect of the powder fraction and viscosity agents often used in SCC on durability. In addition, the effect of the special composition of SCC on the susceptibility to damaging alkali silica‐reactions ASR was investigated. The effectiveness of fly ash as a secondary cementitious material in avoiding damaging ASR when using reactive aggregate was clarified.
