Question 1.
What is the formula for calculating cement content?
Show hintHide hint
Think about how water and cement interact in concrete.
Question 2.
Name one factor that can affect cement content calculations.
Show hintHide hint
Consider the conditions under which concrete will be used.
3Question 3.
What is the maximum cement content as per IS 456?
- 350 kg/m³
- 450 kg/m³
- 500 kg/m³
Show hintHide hint
Think about the standard limits provided in the IS codes.
4Question 4.
True or False: The water-cement ratio only affects the workability of concrete.
- True
- False
Show hintHide hint
Reflect on the definition of the water-cement ratio.
Question 5.
Design a mix for M35 concrete with a target mean strength considering severe exposure. If you have water content of 195 kg, how much cement do you need?
Show hintHide hint
Calculate the target mean strength before finding cement content.
Question 6.
You are designing for high-strength concrete (M60) with a water-cement ratio of 0.35. If you decide to use 210 kg of water, calculate the amount of cement needed ensuring it meets the standards.
Show hintHide hint
Check if the cement content aligns with the performance requirements of M60.
