Understand the concrete mix proportion, preparation condition and transportation condition. Due to better workability of concrete requirement, convenience of construction, ensure access to good grouting quality. Workability means that the concrete mixture is easy to operate (mixing, transportation, irrigation, tamping) and to obtain uniform quality, forming dense. Workability is a comprehensive technical indicator; the concept contains three meanings including liquidity, cohesiveness and water-retaining property. Liquidity means that the concrete mixture can produce flow and perform uniform and dense to fill the template in the own weight or under construction mechanical vibrators. Cohesiveness means that the concrete mixture in the process of construction has certain cohesive force between their constituent materials, does not generate layered segregation phenomenon. Water-retaining property means that the concrete mixture in the process of construction has certain water retention ability, does not have severe bleeding phenomenon. The concrete mixture is occurred bleeding phenomenon, the water secreted form easily permeable voids, which will affect the density of concrete and reduce the quality of concrete.


Above show that the concrete mixture of liquidity, cohesiveness and water-retaining property have their own contents. And all of them are interrelated, but often contradictory. Therefore, the workability is the contradictions unified concept in three aspects of certain specific conditions.
