What grade of concrete is used for pile foundation?

Question

Accepted Answer

The grade of concrete used for pile foundation depends on the load-bearing capacity required and the soil conditions.

The most commonly used grades of concrete for pile foundation are M20, M25, and M30.
The grade of concrete is determined based on the load-bearing capacity required and the soil conditions.
For example, if the soil is weak and the load-bearing capacity required is high, a higher grade of concrete such as M30 may be used.
On the other hand, if the soil is strong and the load-bearing capacity required is low, a lower grade of concrete such as M20 may be used.
The grade of concrete also depends on the type of pile used, such as precast or cast-in-situ piles.

we use M20 to M40 concrete grade
