Aggregate Segregation of Ultra-High Performance Concrete
This article deals with the aggregate segregation of ultra-high performance concrete. The main objective of this research was to determine which aspects of the design most affect segregation. It was studied the change of grading curve, water/powder ratio and consistency. Quartz sand with approximately rounded grains and maximum aggregate size up to 4 mm was used for the production of specimens. Segregation was evaluated after cutting the hardened concrete specimens according to the drop of grains of aggregate. The results show that segregation is by the far most affected by the consistency of concrete. Change of the grading curve or change the water/powder ratio has had no or little influence on segregation.
