Answer / rethina kumar

generally concrete is strong in compression, weak in tension, that is reason we providing reinforcement in tension zone.

1.column is compression zone, so one day is enough to deshutter
2.slab is tension zone, so it need minimum 14 days to deshutter

why compression strenth of concrete is tested with a cube of size 150x150x150 mm ?

A doubly reinforced concrete beam is 25 cm wide and 50cm deep to the centre of tension reinforcement. The centre of compression is steel is 5cm from the compression edge. The areas of the compression and the tension steel are 10.16cm2 and 12.56 cm2 if m=18 and the bending moment at the section is 7,000,000 N-cm. Calculate the stress in concrete and steel.
