Care has to be exercised to ensure that there is no segregation of the coarse aggregate. This is particularly essential in the case of high flowable HPC, since it is typically produced with slumps in excess of 200 mm. Despite the fluid appearance of high flowable HPC, the mixture requires complete consolidation that should be achieved quickly. Vibratory equipment is recommended, with at least one standard vibrator for every three vibrators. Additionally, the ACI 309 guidelines should be used for proper consolidation.
