How do you calculate quantity of water?

Multiply length (L) by width (W) to get area (A). Multiply area by height (H) to get volume (V). Multiply volume by 7.48 gallons per cubic foot to get capacity (C). Find the capacity in gallons of a horizontal circular tank that has a diameter of 8 ft and is 12 ft long.

How many shovel fulls in a 25kg bag of cement?

Regarding this, “how many shovels in a bag of 25kg cement?”, it would take roughly 1 shovels full to move 5kg of cement, here we have 25kg one bag of cement, so our rough estimate is 25/5 = 5 shovels, so, there are 5 shovels full required in a 25kg bag of cement.

How much water is needed to hydrate concrete?

For complete hydration of Portland cement, only about 40% water by mass (a water-to-cement ratio of 0.40) is needed. If a water-to-cement ratio greater than about 0.40 is used, the excess water not needed for cement hydration remains in the capillary pores or evaporates.

Does more water make concrete stronger?

Water plays a critical role, particularly the amount used. The strength of concrete increases when less water is used to make concrete. Concrete is actually mixed with more water than is needed for the hydration reactions. This extra water is added to give concrete sufficient workability.
