IS code for mix design is IS 10262:2009
IS 10262:2009 is the Indian Standard code for concrete mix design
It provides guidelines for proportioning of concrete ingredients based on desired strength and workability
The code covers various factors such as water-cement ratio, aggregate grading, and admixtures
Different grades of concrete are classified based on their compressive strength.
Concrete grades are denoted by M followed by a number, such as M20, M30, etc.
Higher grade concrete has higher compressive strength.
Different grades are used for different types of construction projects.
Common grades include M20, M25, M30, M35, and M40.
Each grade has a specific mix ratio of cement, sand, and aggregates.

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement that hardens over time.
Concrete is made up of a mixture of cement, water, and aggregates like sand and gravel.
It is used in construction for building foundations, roads, bridges, and more.
The strength and durability of concrete can be enhanced by adding additives like fibers or chemicals.
Concrete can be precast of...
Codes required for testing materials used for concrete include ASTM standards, ACI codes, and relevant building codes.
ASTM standards such as ASTM C39 for compressive strength testing
ACI codes like ACI 318 for structural concrete design
Building codes like International Building Code (IBC) for construction requirements
I was interviewed in Jul 2024.
Concrete is a mixture of cement, water, aggregates, and sometimes additives, used in construction. RMC plant is a facility where ready-mix concrete is produced.
Concrete is a composite material made up of cement, water, fine and coarse aggregates, and sometimes additives like fly ash or silica fume.

Connecting to a database has multiple options depending on the type of database and programming language used.
For SQL databases, options include using JDBC for Java, ODBC for C++, and ADO.NET for C#.
For NoSQL databases, options include using MongoDB's driver for Python or Node.js.
ORMs like Hibernate and Entity Framework can also be used to abstract away the database connection details.
Connection strings are used to spe...
I applied via Naukri.com and was interviewed before Jun 2019. There were 3 interview rounds.
Implement stack data structure
Use an array or linked list to store elements
Push operation adds element to top of stack
Pop operation removes element from top of stack
Peek operation returns top element without removing it
Global variables are accessible from any part of the program and can be modified by any function.
Global variables are declared outside of any function.
They can be accessed and modified by any function in the program.
If a function modifies the value of a global variable, the new value is visible to all other functions.
Global variables can be useful for sharing data between functions.
However, overuse of global variables
Program to transpose a matrix
Iterate through rows and columns of the matrix
Swap the elements at (i,j) and (j,i) positions
Return the transposed matrix
Pre and post fix operators are used to increment or decrement a value before or after it is used in an expression.
Pre-fix operator (++x) increments the value of x and returns the new value.
Post-fix operator (x++) returns the value of x and then increments it.
Both operators can be used with variables of numeric data types.
They can also be used with pointers to increment or decrement the memory address they point to.

The number of zeros in the factorial of n depends on the number of factors of 5 in n!
Count the number of factors of 5 in n! to determine the number of zeros
For example, in 10! = 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1, there is one factor of 5, so there is one zero at the end
