A 5-gallon bucket of cement will weigh in at 60lbs for the one bag of pre-mix plus the water's weight added to the mix. Typical concrete pre-mix will require about ½ gallon of water. That's about 4.17 pounds of water weight. Therefore a bucket of cement will weigh about 65 pounds.
This concrete calculator will help you determine the volume of concrete you need in cubic yards, cubic feet, and cubic meters. It also calculates the number of 40lb, 60lb, or 80lb bags of concrete needed, and an estimated cost for the concrete.
The number of 80 lb bags of concrete required for a slab depends on its size. Each 80-pound bag yields approximately 0.022 cubic yards of concrete. For a 4-inch thick, 100-square-foot slab, you'll need 56 bags. It's essential to calculate the volume based on your slab's dimensions.
Cement is a material used to make mortar and concrete and is usually sold in bags of various sizes. The most common bag size is 94 lbs (42.6 kg), but bags can range from as little as 40 lbs (18.14 kg) to as much as 94 lbs (42.6 kg). The weight of a bag of cement can also vary depending on the brand or type of cement.
Input the bag size: Enter the size of the concrete mix bag in pounds (e.g., 60 or 80 pounds). Input the bag yield: Enter the yield of the concrete mix bag in cubic feet (e.g., 0.45 or 0.6 cubic feet). Calculate the number of bags: Click the "Calculate" button to generate the number of bags required for your project. Concrete Bag Calculator
At this point, concrete has achieved about 99% of its strength, and will continue to very slowly strengthen over the next few years. At 28 days old, I use a density of .085 pounds per cubic inch (146.9 pounds per cubic foot) when calculating structural load. Concrete is porous.
Formula for No. of bags of concrete do you need = total cubic yards ÷ bags yields in yards. To determine yields of premixed concrete bag (80lb, 90lb, 60lb, 50lb, and 40lb) in yards, divide the weight of one bag of concrete in pounds by 3600 (because one yard of concrete weighs about 3600 pounds).
Weight of a Cement Bag United States. In the united states, Portland cement is usually supplied in bags having a weight of 94 lbs. (42.6 kg), Canada. Other standards exist in Canada and New Zealand as we find that companies provide cement in bags of 40 kg. UK. In the United kingdom and Ireland,
