What is the primary purpose of using admixtures in concrete mix design?

Step 1: Understand that concrete is made from cement, water, and aggregates (like sand and gravel).
Step 2: Know that sometimes we want to improve how concrete behaves in different situations.
Step 3: Learn that admixtures are special ingredients added to the concrete mix.
Step 4: Realize that these admixtures can make concrete easier to work with (workability).
Step 5: Understand that admixtures can also help concrete last longer (durability).
Step 6: Remember that they can change how quickly the concrete sets (setting time).
Step 7: Conclude that the primary purpose of using admixtures is to enhance these important properties of concrete.
