Multiply the square footage by the depth in feet to find the volume of the space in cubic feet. Volume is found by measuring length × width × depth. Finally, divide the cubic footage by 27 to find the volume in cubic yards. This is the amount of concrete needed.

Businesses that carry out concrete slab work charge an average of $60/m2 for their services. However, the thickness of the slab and the size of the area always affect the cost of the job. Thus, the price goes from $50/m2 to $85/m2.

Average Cost To Pour Concrete To pour a typical 10x10 concrete slab will cost $670 to $930, a 12x12 slab for a patio will cost $796 to $1,476, a 20x24 driveway slab runs between $1,440 and $3,360, and a 24x24 slab for a garage will cost $3,058 to $5,944.

To calculate what you need, multiply the walkway's width and length to find the square footage; for example a 4-foot-wide, 50-foot-long walkway covers 200 square feet. Next, factor in the thickness: 4 inches converts to 0.33 feet; multiply this by the square footage to find the cubic feet: 200 x 0.33 = 66 cubic feet.

Cost. Use $90 per cubic yard as a ballpark figure for concrete prices, but concrete slab cost will vary by region. Also, expect a fee of about $60 per load for delivery from a concrete truck for concrete cost. There could be other fees for such things as Saturday concrete truck delivery and small loads.

Thus, the quantity of cement required for 1 cubic meter of concrete = 0.98/0.1345 = 7.29 bags of cement. The quantities of materials for 1 m3 of concrete production can be calculated as follows: The weight of cement required = 7.29 x 50 = 364.5 kg.

How Much Does Concrete Weigh? The weight of concrete is calculated based on the length, width and thickness of the slab. *A cubic foot or yard of concrete weighs less once it's broken up due to the amount of empty of space now included in the measurement.
