Discussion on slump of concrete mixture Abstract: The workability of fresh concrete, also known as workability, means that the concrete mixture is easy to operate (mixing, transportation, pouring, vibrating) and obtain the performance of uniform quality and dense molding. The slump test method is the most commonly used method to determine the workability of concrete. The reasons affecting the concrete slump are analyzed -
Slump test of concrete mixture Slump is an indicator of consistency of concrete mixture. This test is applicable to concrete with slump greater than 10mm and aggregate particle size not greater than 40mm. Concrete with aggregate particle size not greater than 40mm. For concrete with aggregate particle size greater than 40mm, it is allowed to use an enlarged slump cone, but it should be explained. -
