The test principle is to measure the time for the concrete to be consolidated by vibrating in a cylindrically shaped mold. "1 The main objective of this research was to develop high-performance Roller Compacted Concrete (RCC) with enhanced solid skeleton to secure greater workability, mechanical properties, and frost durability.
