In a concrete mix design, what does the term 'water-cement ratio' refer to?
The ratio of water to the total volume of concrete
The ratio of water to the weight of cement
The ratio of cement to the weight of aggregates
The ratio of fine aggregates to coarse aggregates
The water-cement ratio is defined as the weight of water divided by the weight of cement in a concrete mix, which significantly affects the strength and durability of the concrete.

Q
Q: In a concrete mix design, what does the term 'water-cement ratio' refer to?
Solution: The water-cement ratio is defined as the weight of water divided by the weight of cement in a concrete mix, which significantly affects the strength and durability of the concrete.
Steps: 5
Step 1: Understand that concrete is made of cement, water, and aggregates (like sand and gravel).
Step 2: Know that the water-cement ratio is a way to measure how much water is used compared to the amount of cement.
Step 3: The water-cement ratio is calculated by dividing the weight of the water by the weight of the cement.
Step 4: Realize that this ratio is important because it affects how strong and durable the concrete will be.
Step 5: A lower water-cement ratio usually means stronger concrete, while a higher ratio can make it weaker.
