Water plays a critical role in a concrete mix, and its ratio to the other components is essential. The water-to-cement ratio is typically between 0.4 to 0.6, which means for every 100 pounds of cement, 40 to 60 pounds of water is used. This ratio affects the workability, strength, and durability of the concrete.
