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. 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 We need 6.28 cubic yards (4.8 m 3) of cement, and our producer sells cement in bags weighing 60 lb (25 kg) with a density of 150 lb/cu ft (2400 kg/m 3). The total weight of concrete that we need is 942.53 lb (427.52 kg). We assume a 5% loss in wastage and spillage. So, there you go, we need 17 bags of cement. 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, How much does a cubic foot of concrete weigh? It depends on the density of the concrete. Asphalt concrete with a density of 140.03 lbs/ft 3 would weigh 140.03 lbs ( 63.51 kg ), while reinforced cement concrete with a density of 156.07 lbs/ft 3 would weigh 156.07 lbs ( 70.79 kg ). 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. .
