Q: What is the primary function of admixtures in concrete?
Solution: Admixtures are used to enhance specific properties of concrete, such as workability, setting time, and durability.
Steps: 4
Step 1: Understand what admixtures are. Admixtures are materials added to concrete before or during mixing.
Step 2: Know that the primary function of admixtures is to improve the properties of concrete.
Step 3: Identify specific properties that admixtures can enhance, such as workability (how easy it is to mix and pour), setting time (how quickly it hardens), and durability (how long it lasts).
Step 4: Realize that by using admixtures, we can make concrete better suited for different construction needs.
