Civil Engineer Intern Interview Questions and Answers

Bogue's compound in cement refers to the four main compounds that make up Portland cement.

• Bogue's compound consists of tricalcium silicate, dicalcium silicate, tricalcium aluminate, and tetracalcium aluminoferrite.

• These compounds are responsible for the strength and setting properties of cement.

• The proportions of these compounds in cement can affect its performance and characteristics.

To draw a moment shear diagram, analyze the loading diagram and calculate the shear and moment at each point.

• Identify the type of loading (point, distributed, or concentrated)

• Calculate the reactions at the supports

• Calculate the shear and moment at each point using equations of equilibrium

• Plot the shear and moment values on the diagram

• Connect the points to form the moment shear diagram

Volume of a cube can be calculated by multiplying the length, width, and height of the cube.

• Calculate the volume of a cube by using the formula: Volume = length x width x height

• All sides of a cube are equal, so if you know the length of one side, you can use that as the length, width, and height in the formula

• For example, if the length of a side of the cube is 5 cm, the volume would be 5 x 5 x 5 = 125 cubic cm

Tests on concrete include compressive strength test, slump test, and air content test.

• Compressive strength test measures the ability of concrete to withstand loads

• Slump test measures the consistency and workability of concrete

• Air content test measures the amount of air trapped in concrete

• Other tests include water permeability test, rebound hammer test, and ultrasonic pulse velocity test
