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 do you mean by workability?
workability is the work of the concrete which is done by concrete ability of work is called workability
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.
Why is it important to have workable concrete?
simply workabilty is the w/c ratio in concrete. more the w/c ratio higher the workability and vice versa. and it is true that excess amount of w/c ratio doesnt give proper strength. so workable concrete i.e, concrete with proper w/c is must for good strength. *note: not considering the mix of concrete.
How to make ultra high performance concrete?
silica fume and quartz powder is added to make the concrete more denser. fine aggregates fill the voids between coarse aggegates, cement fill the voids between fine aggregate, silica fume fills the voids between cement and quartz powder fills the voids in between silica fumes
What do you mean by workability?
workability is the work of the concrete which is done by concrete ability of work is called workability
What is the measurement of workability?
Workability of Concrete
What is bycol?
Bycol Clear is an air-entraining admixture used to improve the workability of brickwork mortars and concrete mixes.
What is the effect of grading of aggregate on workability?
Grading of Aggregates enhances workability of concrete.
How does micro silica improve the workability of concrete?
Silpozz Microsilica improves concrete by enhancing strength, reducing permeability, increasing durability, and providing resistance to chemical attacks and environmental stresses.
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....!
What is the slump test normally used to evaluate?
the workability of a concrete mixture
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 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 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 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.
