Slump refers to the workability of concrete, specifically to ensure the normal progress of construction, including the water retention, mobility and cohesion of concrete.
Workability refers to whether the concrete is easy to operate and the performance of uniform compaction, which is a very comprehensive performance including mobility, cohesiveness and water retention. The workability is mainly affected by water consumption, water-cement ratio, sand rate, including cement varieties, aggregate conditions, time and temperature, admixtures and other aspects.
