How many bags of concrete do i need for a 10×15 slab | how much concrete do I need for a 10×15 slab.
Concrete is a blended mix of Portland cement, sand, aggregate, water with approve ingredient. Cement is acts as binder or adhesive materials to bind the components of concrete all together to create workable paste. Sand acts as filler material that fills the voids and gap between components of concrete and remove the air. Aggregate, stone, or gravel used to strengthen the concrete strength.
To determine how many bags of premixed concrete you will need, divide the total cubic yards needed by the yield. Use the following yields per each bag size: A 40 pound bag yields 0.011 cubic yards, 60 pound bag yields 0.017 cubic yards, 50 pound bag yields 0.0138 cubic yards and 80 pound bag yields 0.022 cubic yards.
If you measure their yields in cubic feet, then yields per each bag size are following: A 40 pound bag yields 0.30 cubic feet, 60 pound bag yields 0.45 cubic feet, 50 pound bag yields 0.375 cubic feet and 80 pound bag yields 0.60 cubic feet.
To figure the amount of yards of concrete you will need, take the all measurements Length in feet, width in feet and thickness in inches. Convert thickness in feet. Multiply its length, width and thickness to get cubic footage. Multiply the total cubic footage by 0.037 to get total yards of concrete needed.
How many bags of concrete do i need for a 10×15 slab
If you have a 10×15 slab, you would need approximately 1.83 yards (49.5 cubic feet, or either 83- 80lb, 110- 60lb bags) of concrete at 4″ thick, 2.32 yards (62.55 cubic feet, or either 105- 80lb, 139- 60lb bags) of concrete at 5″ thick, 1.38 yards (37.5 cubic feet, or either 63- 80lb, 84- 60lb bags) of concrete at 3″ thick, or 2.78 yards (75 cubic feet, or either 125- 80lb, 167- 60lb bags) of concrete at 6″ thick.
How many bags of concrete do i need for a 10×15 slab at 4 inches thick
At 4 inches thick, for a 10×15 slab you would need 1.83 cubic yards or 49.5 cubic feet of concrete. If you use premix concrete, either 83 80-Pound, 110 60-pound, 132 50-pound, or 165 40-pound bags of premixed concrete will be required.
Let’s do calculation and proceeds following steps:
● 4″ thickness in feet = 4/12 = 0.33′
● Volume of concrete in cubic feet = 10 × 15 × 0.33 = 49.5
● Volume of concrete in yards = 49.5 × 0.037 = 1.83 yards.
● No. of 80lb bags = 49.5/0.60 = 83 bags
● No. of 60lb bags = 49.5/0.45 = 110 bags
● No. of 50lb bags = 49.5/0.375 = 132 bags
● No. of 40lb bags = 49.5/0.30 = 165 bags
