What is the main purpose of using admixtures in concrete?
Correct Answer: Admixtures ka main purpose concrete ki workability, durability aur dusre properties ko improve karna hai bina iski composition ko zyada badle.
Step 1: Understand that concrete is made of cement, water, sand, and gravel.
Step 2: Know that sometimes we want to change how concrete behaves without changing its main ingredients.
Step 3: Learn that admixtures are special materials added to concrete to help with this.
Step 4: Realize that admixtures can make concrete easier to work with (workability).
