Final answer:
The weight of water typically ranges from 20% to 40% of the total weight of cement in a common concrete mix, which is important for achieving the desired concrete properties.
Step-by-step explanation:
The question you've asked pertains to the properties of concrete, specifically the weight of water as a percentage of the total weight of cement in a common concrete mix. In engineering, particularly in the field of construction, the typical range is from 20% to 40% of the total weight of the cement. It is crucial to maintain the water-cement ratio within proper limits to achieve the desired strength and durability of the concrete.
