How many bags of concrete do i need for a 8×12 slab | how much concrete do I need for a 8×12 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 8×12 slab
If you have a 8×12 slab, you would need approximately either 40 80-pound, or 54 60-pound (0.888 yards, or 24 cubic feet) bags of premixed concrete at 3 inches thick, 54 80-pound, or 72 60-pound (1.184 yards, or 32 cubic feet) bags of premixed concrete at 4 inches thick, 67 80-pound, or 89 60-pound (1.48 yards, or 40 cubic feet) bags of premixed concrete at 5 inches thick, or 80 80-pound, or 107 60-pound (1.776 yards, or 48 cubic feet) bags of premixed concrete at 6 inches thick.
How many bags of concrete do i need for a 8×12 slab at 3 inches thick
At 3 inches thick, for a 8×12 slab you would need approximately either 40 80-Pound, 54 60-pound, or 80 40-pound bags of premixed concrete. If you measure in yards, 0.888 cubic yards (24 cubic feet) of concrete will be required.
Let’s do calculation and proceeds following steps:
● 3″ thickness in feet = 3/12 = 0.25′
● Volume of concrete in cubic feet = 8 × 12 × 0.25 = 24
● Volume of concrete in yards = 24 × 0.037 = 0.888 yards.
● No. of 80lb bags = 24/0.60 = 40 bags
● No. of 60lb bags = 24/0.45 = 54 bags
● No. of 40lb bags = 24/0.30 = 80 bags.
How many bags of concrete do i need for a 8×12 slab at 4 inches thick
At 4 inches thick, for a 8×12 slab you would need approximately either 54 80-Pound, 72 60-pound, or 107 40-pound bags of premixed concrete. If you measure in yards, 1.184 cubic yards (32 cubic feet) of concrete will be required.
Let’s do calculation and proceeds following steps:
● 4″ thickness in feet = 4/12 = 0.333′
● Volume of concrete in cubic feet = 8 × 12 × 0.333 = 32
● Volume of concrete in yards = 32 × 0.037 = 1.184 yards.
● No. of 80lb bags = 32/0.60 = 54 bags
● No. of 60lb bags = 32/0.45 = 72 bags
● No. of 40lb bags = 32/0.30 = 107 bags.
How many bags of concrete do i need for a 8×12 slab at 5 inches thick
At 5 inches thick, for a 8×12 slab you would need approximately either 67 80-Pound, 89 60-pound, or 134 40-pound bags of premixed concrete. If you measure in yards, 1.48 cubic yards (40 cubic feet) of concrete will be required.
Let’s do calculation and proceeds following steps:
● 3″ thickness in feet = 5/12 = 0.417′
● Volume of concrete in cubic feet = 8 × 12 × 0.417 = 40
● Volume of concrete in yards = 40 × 0.037 = 1.48 yards.
● No. of 80lb bags = 40/0.60 = 67 bags
● No. of 60lb bags = 40/0.45 = 89 bags
● No. of 40lb bags = 40/0.30 = 134 bags.

How many bags of concrete do i need for a 8×12 slab at 6 inches thick
At 6 inches thick, for a 8×12 slab you would need approximately either 80 80-Pound, 107 60-pound, or 160 40-pound bags of premixed concrete. If you measure in yards, 1.776 cubic yards (48 cubic feet) of concrete will be required.
Let’s do calculation and proceeds following steps:
● 6″ thickness in feet = 6/12 = 0.5′
● Volume of concrete in cubic feet = 8 × 12 × 0.5 = 48
● Volume of concrete in yards = 48 × 0.037 = 1.776 yards.
● No. of 80lb bags = 48/0.60 = 80 bags
● No. of 60lb bags = 48/0.45 = 107 bags
● No. of 40lb bags = 48/0.30 = 160 bags
Cost estimate for a 8×12 slab
For the most part, the typical concrete slab price range of $4 to $8 per square foot includes labour. A 8×12 slab is a 96 square foot. Using ready-mix concrete to cover 8×12 (96 sq ft) at a depth of 4″ to 6″-8″, the estimated cost is range between $384 to $768 (96× $4 = $384 or 96×$8 = $768).
How much does a 8’×12’×4″ concrete slab cost?
Pouring a concrete slab may cost between $4 and $8 per square foot. A 4″ thick slab will cost an average cost of $4 per square foot. Based on the national average, a 8’×12’×4″ (96 square feet) concrete slab may cost about $384 (96 times $4 = $384).
How much does a 8’×12’×5″ concrete slab cost?
Pouring a concrete slab may cost between $4 and $8 per square foot. A 5″ thick slab will cost an average cost of $5 per square foot. Based on the national average, a 8’×12’×5″ (96 square feet) concrete slab may cost about $480 (96 times $5 = $480).
How much does a 8’×12’×6″ concrete slab cost?
Pouring a concrete slab may cost between $4 and $8 per square foot. A 6″ thick slab will cost an average cost of $6 per square foot. Based on the national average, a 8’×12’×6″ (96 square feet) concrete slab may cost about $576 (96 times $6 = $576).
How much does a 8’×12’×8″ concrete slab cost?
Pouring a concrete slab may cost between $4 and $8 per square foot. A 8″ thick slab will cost an average cost of $8 per square foot. Based on the national average, a 8’×12’×8″ (96 square feet) concrete slab may cost about $768 (96 times $8 = $768).
