To improve the workability of concrete, issue to be concerned of as below:

- increase water/cement ratio

- increase size of aggregate

- use well-rounded and smooth aggregate instead of irregular shape

- increase the mixing time

- increase the mixing temperature

- use non-porous and saturated aggregate

- with addition of air-entraining mixtures

What is the importance of slump test in concrete work?

The importance of slump test in concrete work is to ensure consistency in the concrete. The test measures the workability of the concrete.


What is the difference between concrete grade C35 and C35A?

The main difference between concrete grade C35 and C35A lies in their composition. C35 concrete is a standard concrete mix with a minimum strength of 35 megapascals (MPa), while C35A concrete is a special mix that includes air-entraining agents to improve workability and durability. The inclusion of air-entraining agents in C35A helps to increase the concrete's resistance to freeze-thaw cycles and reduce the risk of cracking. Overall, C35A is more suitable for applications where improved durability and workability are required.


What is the purpose of a plasticiser of a concrete?

A plasticiser is used in concrete to improve its workability and fluidity without adding excess water. By reducing the surface tension of the mix, it allows for easier placement and compaction, which can enhance the overall strength and durability of the finished product. Additionally, plasticisers can help reduce the risk of segregation and bleeding in the concrete.


What is compacting factor of concrete?

The compacting factor of concrete is a measure of its workability, indicating the ease with which concrete can be mixed, placed, and finished. It is determined by comparing the weight of a partially compacted concrete sample to the weight of the same volume of fully compacted concrete. A higher compacting factor suggests better workability, while a lower factor indicates that the concrete may be too dry or difficult to work with. This test is particularly useful for assessing the suitability of concrete mixes for various construction applications.

Do they have lime in concrete?

Yes, lime is one of the ingredients in concrete mixes. It is used to improve workability and reduce the amount of water needed in the mix, which ultimately helps increase the strength and durability of the concrete.


How the changing of workability when the concrete mixture containing high aggregate content?

Aggregate to cement ratio is an important thing which affects the workability....! If the aggregate/cement ratio is higher , the concrete will be Leaner. Less quantity of paste is available for lubrication, Hence workability decreases..!! On the other hand if the aggregate/cement ratio is lower, the concrete will be fatty. Higher quantity of paste is available for lubrication. Hence workability increases. ! Thus Higher aggregate content leads to lowering of workability....!

How does Silpozz impact workability in concrete?

Silpozz improves workability by reducing segregation and bleeding, resulting in a more cohesive and easy-to-handle mix.


What is the workability of concrete?

The property of concrete which determines the amount of useful work (like- water content, mix proportion, size of aggregate used and use of admixtures) necessary to produce full compaction is called workability.
