about 3600 pounds Click to see full answer. Besides, does concrete weigh more wet or dry?Some excess water is almost always added to the concrete mix to improve its workability, and this portion will evaporate over time. However, that excess water should be minimal. In short, dry concrete and wet concrete mix each weigh about the same; roughly 2 tons per cubic yard.Subsequently, question is, how many 80 pound bags of concrete does it take to make a yard? The finished volume of an 80# bag of Sacrete or Quikrete (pre-mixed cement, sand and gravel) is 0.6 cubic foot (stated on the bag). There are 27 cubic feet in a cubic yard. Dividing 27 cubic feet by the volume of the bag will give you the number of bags you need. In this manner, how much does a yard of concrete weigh? 4050 lbs How much does a 4 inch slab of concrete weigh?The weight of concrete is approximately 150 pounds per cubic foot, or 4,050 pounds per cubic yard. The formula for calculating the weight of concrete is: Length (in feet) x Width (in feet) x Thickness (in inches) /12 x 150 = weight (in pounds).
