Why is it important to use the correct water-to-cement ratio in concrete?

Using the correct water-to-cement ratio is crucial because it directly impacts the strength and durability of the finished product. The water-to-cement ratio determines the final properties of the concrete, including its compressive strength, durability, and resistance to environmental factors. A lower ratio generally results in a stronger, denser, and more durable concrete, whereas a higher ratio can lead to a weaker and more porous material that is susceptible to damage.

A balance between workability and strength is necessary when mixing concrete; too much water can make the mix easier to work with initially but compromises its long-term performance. Thus, maintaining an appropriate water-to-cement ratio is a fundamental aspect of achieving quality concrete that meets structural and performance requirements.
