1) Generally for concreting under water we use concrete of
grade M20 or above and use plasticizers which reduce the
setting time and most imptly concrete shud not be released
from a height above 1 to 1.5 meter.
4) In one way slab, reinforcement is designed in such a way
that load is taken only by main steel and the purpose of
distributed steel is only to keep mail steel in position.
Whereas in two way slab, steel design is made suchthat load
is distributed over sntire reinforcement.
5) %age of steel by area in RCC beams and columns must
be < 4% and exact % depends on design of the structure.
