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). A cubic yard of concrete's average weight is 4,050 lbs, or 150 lbs per cubic foot. Quikrete concrete bags come in 40lb, 50lb, 60lb, & 80 lb. 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. 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 ). How much area can one bag of cement cover? 4 sq feet in that amount of cement. How much sand and cement do I need for 1 cubic meter of concrete? 1 Cubic Meter of Concrete 1m3 of concrete = 150l water + 250kg cement + 700kg sand + 1200kg aggregates. How much Builders mix do I need for 1m3 of concrete? Bags of Cement to Builders mix: 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. 2s80vOa.
