Which of the following statements about concrete is correct?
Concrete with a high water-cement ratio will be stronger than concrete with a low water-cement ratio.
Concrete can be used for structural elements like beams and columns without reinforcement.
The addition of more cement to concrete mix will always increase its strength.
Concrete’s strength is primarily determined by the water-cement ratio rather than the amount of cement used.
Correct answer
Concrete with a high water-cement ratio will be stronger than concrete with a low water-cement ratio.
Which of the following statements about concrete is correct?
Concrete can resist both compression and tension without reinforcement.
The presence of air in concrete improves its strength and makes it more durable.
Concrete is a poor conductor of heat, which makes it ideal for thermal insulation.
Concrete is best suited for compressive applications but requires reinforcement for tensile stress.
Correct answer
Concrete can resist both compression and tension without reinforcement.
