We are required to cast a RCC Slab of 600 mm depth and size 21M x 11M. in 2 parts of one day duration each ( Non-continuous) at 3.8 m lvl above G,.L.
The constraints are:
1) Mixing of M20 grade of concrete ( Cement quantity 401 Kg.per Cu.M. of concrete) by concrete mixers at site
2) Manual placing of concrete
What should be the sequence of concreting to avoid formation of a cold joint?
Will there be any creep if at all such joints are formed?
How the construction joints shall be treated to avoid such problems?
Will use of chemicals for reducing setting time affect the strength of concrete?
Any advise on the matter will be of great help
