What is the purpose of using admixtures in concrete?
Correct Answer: Admixtures are used to enhance specific properties of concrete.
Step 1: Understand what admixtures are. Admixtures are materials added to concrete to improve its properties.
Step 2: Identify the specific properties that can be enhanced. These include workability (how easy it is to mix and place), setting time (how quickly it hardens), and durability (how long it lasts).
Step 3: Learn how each property is affected. For example, some admixtures make concrete easier to work with, while others help it set faster or last longer.
Step 4: Recognize that using admixtures allows builders to customize concrete for different projects and conditions.
