FAQs
How many bags of concrete make a yard?
A cubic yard of concrete requires roughly 45 bags of 80lb pre-mixed concrete, or about 6 to 7 standard 50kg bags of cement if you are mixing it yourself with sand and aggregate.
How do I calculate concrete for a circular slab?
To calculate the volume of a circular slab, use the formula: Area = π × radius² × thickness. Once you have the total cubic volume, input it into the calculator above to find the material quantities.
