How to pour Concrete in Narrow/Sleak Columns?
You can use Self Compacted Concrete to use for narrow columns. It also used where the reinforcement is heavy and process of compaction is not available/difficult to compact.

See lessWhat is the percentage of stone dust that can be added along with fine aggregate in different designs of concrete (Say M-20)? What is the difference between the concrete with and without dust? Does adding dust helps in increasing/decreasing strength?
Difference between concrete with and without dust: The compressive strength of concrete will increase after adding dust in it. Various research shows maximum compressive strength at 60% dust used in concrete. When we talk about workability then dust concrete has low workability as compared to no dusRead more

I hope so you found my answer more helpful to you.
Thank You.

What type of reinforcement used in prestressing concrete? Is it either the standard reinforcement used in conventional RCC structure, or is there any particular type or category of reinforcement for prestressing?
Hi, The prestressing steel used for prestressed concrete can take the form of Tendons Cables Wires – (Plain wire and Indented Wire) Strands –(Two-wire, three-wire and seven-wire strand) Bars The types of prestressing steel are: Cold Worked Prestressing steel Stress-relieving prestressing steel StraiRead more

Difference between Reinforcing Steel and Prestressing Steel
Both R.C.C and Prestressed Concrete employs steel bars or wires in order to sustain tension. But both the types of concrete make use of different steel.
The steel used by R.C.C concrete can be:
The steel used in Prestressed Concrete are wires, strands, solid bars as mentioned above. Prestressed concrete uses high tensile strength steel that is manufactured by increasing the carbon content in steel compared to ordinary mild steel used in R.C.C.
In prestressed concrete, the steel used is tensioned or prestressed. This results in loss of prestress in a range of about 20%. The use of mild steel bars or HYSD bars bring a greater loss than this value. Hence, it is necessary to have high strength tensile bars for prestressed concrete.

What should one do if the slump test fails for a given concrete?
If the slump test fails for concrete then immediately reject that concrete because high amount of water can decrease the durability of the concrete. But dont add water if the slump test fails.
