One more option is core cutting which I do not recommend as it requires coring of the RCC member at multiple places which again affects strength and durability and chances of cutting of steel hence I did not include in this. Although as per ACI actual strength of concrete is considered as 85% of cylinder strength.

What should be the strength after 56 days and should the cubes to be kept under curing for 56 days?
@EverythingCivil3 жыл бұрын
Yes 56 days strength to be checked only if strength not achieved at 28days.. yes to be cured till 56 days.

Sir if some portion of column concreting one day then after how many days should concreting done remaining portion.
@EverythingCivil3 жыл бұрын
You can do it next day no issues. Make sure that old surface is properly roughened to expose aggregate and use proper bonding agent like cement slurry

@@EverythingCivil sir my doubt is the first portion not getting strength and even concreting is done above it
@EverythingCivil3 жыл бұрын
Look after one day the column will definitely not have enough strength to take the design load. But it will definitely have the strength to take the upper portion of concrete which is casted. The casting height of upper portion should be less than 1m then it's ok. Other wise it is better to wait for 3days.

Sir can we use saline water in concrete making If not what is reasons?
@EverythingCivil3 жыл бұрын
No it cannot be used. initially you will get large strength gain but later on strength will reduce of concrete due to the crystallization of the salt particles which is water.
