Brazil Nut Effect; Particle Packing; size segregation; DEM
Abstract :
[en] This chapter presents evidence of the impact of the Brazil Nut Effect on concrete’s particulate
structure on meso-level (aggregate) as well as on micro-level (cement paste). Brazil nut effect
is compared to more commonly recognized features like the wall effect. The information is
mostly obtained on virtual concrete produced by discrete element modelling systems. The
requirements imposed on such systems are indicated and compared to sequential random
addition systems that are still common in concrete technology. In the present case use is
therefore made of so called dynamic solutions of physical concurrent algorithm-based
modeling systems. Some consequences of BNE for structure and properties are discussed.
