Q4. What you do if compressive strength test of concrete fails, why we do test at 3 days, 7 days , 28 days
Ans. 
If compressive strength test of concrete fails, investigate potential causes like incorrect mix proportions or curing methods. Testing at 3, 7, and 28 days allows for monitoring strength development over time.
• Investigate potential causes of failure such as incorrect mix proportions, improper curing methods, or testing errors

• Consider retesting samples to confirm results and identify any discrepancies

• Testing at 3 days pr...read more

Q2. BMD of a frame
Ans. 
BMD of a frame refers to the bending moment diagram which shows the variation of bending moment along the length of a structural frame.
• BMD is a graphical representation of the variation of bending moment in a structural frame.

• It helps in analyzing the internal forces and stresses in the frame.

• BMD is typically plotted with the bending moment on the y-axis and the length of the frame on the x-axis.

• The BMD can be used to ...read more

Q1. How to select a conductor?
Ans. 
Conductors are selected based on factors like material, size, insulation, and current carrying capacity.
• Consider the material of the conductor (e.g. copper, aluminum)

• Determine the size of the conductor based on the current it will carry

• Choose the appropriate insulation for the conductor based on the environment it will be used in

• Ensure the conductor has the required current carrying capacity for the application

Q1. How to find grades of concrete which is already mixed
Ans. 
Grades of concrete in a mixed batch can be estimated by performing a slump test and conducting compressive strength tests on samples.
• Perform a slump test to determine the workability of the concrete mix.

• Take samples from the mixed batch and cast test specimens for compressive strength testing.

• Conduct compressive strength tests on the specimens to determine the grade of concrete.

• Compare the test results with the standar

Q3. Plastering work calculation for different size of wall
Ans. 
Plastering work calculation involves determining the surface area of the wall and the thickness of the plaster.
• Calculate the surface area of the wall by multiplying the height and length of each wall segment.

• Determine the total surface area to be plastered by adding up the surface areas of all wall segments.

• Multiply the total surface area by the desired thickness of the plaster to get the volume of plaster needed.

• Consi...read more
