Which grade of concrete normal use for rcc

Question

Accepted Answer

The grade of concrete normally used for RCC is M20.

The grade of concrete for RCC (Reinforced Cement Concrete) is determined based on the design requirements and structural considerations.
The most commonly used grade of concrete for RCC is M20, which means the concrete mix has a compressive strength of 20 megapascals (MPa) after 28 days of curing.
Other grades of concrete like M25, M30, M35, etc., can also be used depending on the specific project requirements and structural design.
The selection of the concrete grade is influenced by factors such as the type of structure, load-bearing capacity, exposure conditions, and durability requirements.
For example, for residential buildings, M20 grade concrete is generally sufficient, while for high-rise structures or heavy industrial constructions, higher grades may be used.
