Workability and mechanical properties of alkali-activated fly ash-slag the fresh aafs concrete was then immediately cast construction and building. Workability depends on the batching in fine elements, quantity of water, temperature, batching in cement and so on high workability will cause segregation in concrete to know the workability of concrete slump test is done on site see “all about slump test” 2 setting: changing the concrete state from plastic to hardened state is called setting of concrete the time concrete takes to change the state is the setting time. Properties of concrete in its fresh state are very important because the influence the quality of the hardened concrete the fresh concrete has the following procedure consistency workability settlement & bleeding plastic shrinkage loss of consistency 1 consistency consistency of a concrete mix is a measure of the stiffness or sloppiness or fluidity of the mix for effective handling, placing and compacting the concrete, consistency must be the same for each batch.
The workability of a concrete mix gives a measure of the ease with which fresh concrete can be placed and compacted the concrete should flow readily into the form and go around and cover the reinforcement, the mix should retain its consistency and the aggregates should not segregate there are four factors that can affect the workability are: 1. Concrete slump test is an on-the-spot test to determine the consistency as well as workability of fresh concrete this test plays a vital role in ensuring immediate concrete quality in a construction project. Properties of fresh concrete for construction works workability of concrete concrete workability is the relative ease with which a fresh mix can be handled, placed, compacted, and finished without segregation or separation of the individual ingredients.Download
