a yard of concrete can weigh from 2000 to 3500 lbs. The weight difference is because of the water, sand, and gravel mixture being different for different types of concrete.
Wet concrete is approximately 150 pounds per cubic foot. So 80 pounds is approximately 1/50 th of a cubic yard.
Depends how wide the 3 yard length is and how deep the concrete is put over that area.
It depends on the density of the material. Cubic yards is a measure of volume. Pounds is a measure of weight. For example, one cubic yard of feathers will weigh fewer pounds than one cubic yard of lead.
According to the related link below; the required amount to cover 1 square yard with 4 inches of concrete is 6.6 60 pounds bags.
A cubic yard of concrete typically weighs between 3,000 to 4,000 pounds (1.5 to 2 tons) depending on the density of the concrete mix.
One yard of delivered concrete costs $250 dollars. This is true if using a ready mix truck. A yard of concrete weighs approximately 4200 pounds. The price varies according to where you live and the grade of concrete.
Each 60 pounds bag of ready mix concrete will make .45 cubic foot of concrete. There are 27 cubic feet in a cubic yard. You will need 60 bags of 60 pound premixed concrete to make 1 cubic yard.
According to the related link below; the required amount to cover 1 square yard with 4 inches of concrete is 6.6 60 pounds bags.
Wet concrete weighs approximately 4,000 pounds per square yard. That amount varies depending on the water content. Lightweight concrete weighs about 1,000 pounds less.
To determine the pounds of concrete needed to repave a highway, you first need to know the total area to be repaved (in square feet) and the thickness of the concrete layer (in feet). Multiply the area by the thickness to get the volume in cubic feet, then convert that to cubic yards (1 cubic yard = 27 cubic feet). Finally, multiply the volume in cubic yards by the weight of concrete (approximately 4,000 pounds per cubic yard) to find the total weight in pounds.
