The minimum grade of concrete for RCC (Reinforced Cement Concrete) is M20.
The minimum grade of concrete for RCC is determined based on the structural requirements and design specifications.
The grade of concrete is denoted by the mix ratio of cement, sand, and aggregate.
M20 grade concrete means that the mix ratio is 1:1.5:3, where 1 part of cement, 1.5 parts of sand, and 3 parts of aggregate are used.
This grade of concr...
The ratio of M25 refers to the mix proportion of concrete, where M represents the mix and 25 represents the compressive strength of concrete in megapascals (MPa).
M25 is a commonly used mix proportion for concrete in construction.
The M in M25 stands for mix, indicating the type and proportion of materials used in the concrete mix.
The number 25 in M25 represents the target compressive strength of the concrete in megapasc...
Lapping length is the overlap of two reinforcing bars to ensure continuity, while development length is the length required to transfer the stress from the bar to the surrounding concrete.
Lapping length is used to maintain the strength and integrity of reinforced concrete structures.
It is necessary to provide lapping length to ensure the load is transferred smoothly from one bar to another.
The lapping length is typical...
Development length is the length of reinforcement required to transfer the stress from the steel to the surrounding concrete.
It is the minimum length of reinforcement bars that must be embedded in concrete to ensure proper bond strength.
Development length depends on factors like bar diameter, concrete strength, and type of reinforcement.
It is necessary to prevent the steel bars from slipping or pulling out of the concr...
ld for M25 and Fe500 is not a standard term in civil engineering.
ld is not a standard term in civil engineering
It is possible that the interviewer meant to ask for something else
M25 and Fe500 are grades of concrete and steel respectively
The equation Ld = 50x dia of bar relates the development length (Ld) of a reinforcement bar to its diameter.
The development length is the length of bar required to transfer the stresses between the reinforcement and the concrete.
The equation suggests that the development length is 50 times the diameter of the bar.
For example, if the diameter of the bar is 10 mm, the development length would be 500 mm.

Recursion is a process in which a function calls itself. Inheritance is a mechanism in OOP where a class inherits properties of another class. Heap is a region of memory used for dynamic memory allocation.
Recursion can be used to solve problems that can be broken down into smaller sub-problems.
Inheritance allows for code reuse and helps in creating a hierarchy of classes.
Heap is used for dynamic memory allocation in la...
