Dear Sir
Curing of Slab and Beams not sprinkled with water. We made confined stagnation of water for min�21Days (though the CPWD specifications restrict to lesser days) by all round raised mortar�bands or laying one brick height�on all outer wall positions. So that min 2 to 3'' of water height is maintained throughout the day and night for 21 days.
It may not match immersion of cube strength�of curing on all sides, but in slab it is restricted only on top and sides.�
There may not be much variation for the above type of curing , but theoretically�both are not equivalent.
Pl refer the RCC portion of CPWD specification�Vol-I in which the chapter� clearly state the casting, curing, testing, acceptance criteria and payment details based on strength and acceptance criteria for slight;y lesser valve�of cube strength.
With regardsS.Arunachalam
