Factors affecting the strength of concrete:
Effect of water cement ratio:
- The water cement ratio directly affects the strength of concrete.
- A higher water cement ratio leads to lower strength as it results in a more porous concrete with reduced durability.
Effect of fineness of cement:
- The fineness of cement plays a crucial role in determining the strength of concrete.
- Finer cement particles provide a larger surface area for hydration, resulting in better bonding between the cement paste and aggregates.
- This enhanced bond leads to higher compressive strength of concrete.
Effect of curing time:
- Curing is the process of maintaining adequate moisture and temperature conditions for concrete to achieve its maximum strength.
- Longer curing periods allow for more complete hydration of cement particles, resulting in higher concrete strength.
- Decreasing the curing time can lead to inadequate hydration and lower strength.
Effect of size of aggregate:
- The size of aggregate used in concrete also influences its strength.
- Larger aggregates may result in higher water demand, leading to a higher water cement ratio and reduced strength.
- Smaller aggregates provide better packing, resulting in denser concrete with higher strength.
Explanation of the correct answer:
- The correct answer is option 'B', which states that the strength of concrete increases with an increase in the fineness of cement.
- This is because finer cement particles provide a larger surface area for hydration, leading to better bonding and higher compressive strength of the concrete.
- Therefore, using finely ground cement can enhance the overall strength and performance of the concrete.
