Match List-I (material Characteristics) with List-II (Property of Con...
Answer:
The correct matching of List I with List II is:
A. Water-cement ratio - 2. Compressive strength
B. Water content - 4. Workability
C. Minimum cement content - 1. Durability
D. Segregation - 3. Stability of mix
Here is the detailed explanation for each match:
A. Water-cement ratio - 2. Compressive strength:
The water-cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix. This ratio significantly affects the compressive strength of concrete. A lower water-cement ratio leads to higher compressive strength because less water results in stronger hydration of cement particles.
B. Water content - 4. Workability:
Water content in concrete refers to the amount of water added to the mix. It affects the workability of concrete, which refers to its ease of mixing, placing, and finishing. The correct amount of water is necessary to achieve the desired workability for different construction applications.
C. Minimum cement content - 1. Durability:
The minimum cement content in concrete specifies the minimum amount of cement required per unit volume of concrete. It is an important factor for ensuring the durability of concrete structures. Adequate cement content is necessary to provide sufficient strength and resistance against environmental factors such as moisture and chemical attacks.
D. Segregation - 3. Stability of mix:
Segregation in concrete refers to the separation of coarse aggregate particles from the rest of the mix. It can occur due to excessive vibration, improper mix proportions, or inadequate workability. Segregation can negatively impact the stability of the concrete mix, leading to non-uniform properties and reduced strength.
Therefore, the correct matching is:
A-2, B-4, C-1, D-3.
