Topic: Used M15 (1:2:4) mix ratio with PPC cement for casting ground floor house roof slab

My contractor used M15 (1:2:4) mix ratio for casting the ground floor roof slab of thickness 5 inch. The total area is 1400 sqft and maximum room size is 14 x 14 feet.

The contractor says there is no need for M20 since we used TATA TMT 10mm and 8mm with spacing 6 inch, and Ultratech PPC cement which gives the final strength almost equal to M20. 

Is it right? Do I need to worry about anything?

Dear Vinu,
         I am in view that you should use cement concrete 1;1.5;3 for beam and slab. The latest norm due to earth quack is that all the cement concrete should be M 20.
Further I tell you that M20 have 133% strength with comparison of M15 i.e 33 % extra strength. If You have 14'x 14' room/hall size at first floor than lay hidden beam on one side in the slab the beam size may be 9''x 6''.
