Directions: In the following question, a statement of Assertion (A) is followed by a statement of Reason (R).
Select the correct option.
Assertion (A): The compressive strength of concrete is significantly influenced by the water-cement ratio.
Reason (R): A higher water-cement ratio leads to more hydration, resulting in increased compressive
strength of concrete.
Water- cement Ratio & strength of cement is governed by Abram’s law, Detailed below-
|
Water-cement ratio |
Effect on concrete |
|
Low |
High strength, dense concrete, low work |
|
High |
More workability, low strength |
Thus, Assertion is true, However, Reason is false as a higher water cement ratio gives lower strength.
