Plain cement concrete is equally strong in compression as well as in tension
Slump test is performed to check concrete strength
Curing of concrete is done for proper compaction of cement
Fineness modulus is the index number expressing the relative sizes of both coarse and fine aggregates
Answer is Right!
Answer is Wrong!
The correct answer is: B. Slump test is performed to check concrete strength.
A slump test is a method of measuring the consistency of fresh concrete. It is a simple test that can be performed on site to ensure that the concrete is workable and will achieve the desired strength. The test involves pouring a measured amount of concrete into a cone-shaped mold and then allowing it to slump under its own weight. The amount of slump is then measured and used to determine the consistency of the concrete.
A slump test is not a perfect measure of concrete strength, but it is a useful tool for ensuring that the concrete is workable and will achieve the desired strength.
The other options are incorrect for the following reasons:
- Option A is incorrect because plain cement concrete is not equally strong in compression as well as in tension. Concrete is much stronger in compression than in tension. This is why concrete beams are designed to be under compression, and why concrete columns are designed to be under compression.
- Option C is incorrect because curing of concrete is done to prevent the concrete from drying out and to allow the cement to hydrate. Curing is not done for proper compaction of cement.
- Option D is incorrect because fineness modulus is the index number expressing the relative sizes of both coarse and fine aggregates. It is not an index number expressing the relative sizes of just the fine aggregates.
