Step 1 Know that the formula for calculating concrete consists of the following: ( (length x width x height)/27) x 1.05 = Total concrete needed plus 5 percent extra. The length, width and height are measured in feet.
The base area of a concrete cylinder is equal to its volume divided by its height. Say a concrete cylinder has a volume of 340 cubic inches and a height of 12 inches. Its area will then be 340 in³ / 12 in = 28.33 in². Consequently, its diameter would be equal to: √(4 × area / π) = √(4 × 28.33 / π) = 6.005 in ≈ 6 inches.

A basic mixture of mortar can be made using the volume proportions of 1 water : 2 cement : 3 sand. Most of the student activities can be conducted using this basic mixture. Another "old rule of thumb" for mixing concrete is 1 cement : 2 sand : 3 gravel by volume. Mix the dry ingredients and slowly add water until the concrete is workable.
Provide the dimensions (length, width and height) and quantity of your concrete slabs or an area that you want to pave. Determine the weight of all of those elements - this is how bagged cement is sold, they tell you how much the concrete from the bag will weigh (for example, you'll get 60 pounds of concrete out of one bag).
What is the formula for quantity calculation? Thus, the quantity of cement required for 1 cubic meter of concrete = 0.98/0.1345 = 7.29 bags of cement. The quantities of materials for 1 m3 of concrete production can be calculated as follows: The weight of cement required = 7.29 x 50 = 364.5 kg. Weight of fine aggregate (sand) = 1.5 x 364.5 = 546 ...
