During the construction process, in order to facilitate the transportation, pumping, pouring, vibration and other construction processes of concrete, it is required that the concrete must have good workability, and there should be no layering, segregation or bleeding of the concrete.
The workability of concrete is a crucial step before structural formation, hardening, and strength generation, as well as a guarantee for the later strength and durability of concrete structures.
The workability of concrete is a comprehensive indicator, which includes fluidity, cohesiveness, and water retention.
