Question 1.
What does workability in concrete refer to?
Show hintHide hint
Think about the ease of handling concrete.
Question 2.
What is the typical water-cement ratio range?
Show hintHide hint
Consider the parameters of strength and workability.
3Question 3.
What is the primary purpose of concrete mix design?
- To reduce costs
- To achieve required properties
- To determine aggregate type
Show hintHide hint
Consider the benefits of proper mixing.
4Question 4.
True or False: A lower water-cement ratio typically results in higher strength.
- True
- False
Show hintHide hint
Remember the balance of strength versus handling.
Question 5.
You are tasked to design a concrete mix for a bridge that experiences severe weather conditions. Outline your approach including material choices and expected performance.
Show hintHide hint
Always think about environmental impacts and structural needs.
Question 6.
If a concrete mix requires 400 kg of cement, uses a water-cement ratio of 0.4, and has 1000 kg of coarse aggregates, calculate how much fine aggregates you would need based on typical proportions.
