What is the purpose of the water-cement ratio in concrete?

Step 1: Understand that concrete is made of cement, water, and aggregates (like sand and gravel).
Step 2: The water-cement ratio is the amount of water compared to the amount of cement in the mix.
Step 3: A lower water-cement ratio means less water, which usually makes the concrete stronger.
Step 4: A higher water-cement ratio means more water, which can make the concrete weaker and less durable.
Step 5: The right water-cement ratio helps ensure that the concrete can withstand pressure and last a long time.
