Note: This design is valid when the ratio of slab length to width is less than 2 i.e L/W < 2.
For example, if slab width is 10m then slab length must be less than 20m.
This design is based on ACI 318-11 and BNBC 93 and you may find this as conservative.
Note: 1 MPa = 145 psi
Please provide a value between 2000psi and 4000psi (13.7MPa and 27.6MPa):
