At a thickness of 6 inches, for a 10×10 slab, you will need concrete bags of 111 to 60 pounds or 84 to 80 pounds or 168 to 40 pounds. Therefore, 111 to 60 lb or 84- 80 lb or 168 to 40 lb concrete bags will be required for a 10×10 slab with a thickness of 6″. This series of specific calculators has been developed to help you plan your project. You can calculate how much concrete, cement, sand, mortar or plaster you will need.

For each calculation, you'll need to know the dimensions of your object. The calculator will perform the sums for you; where relevant, it will add a small percentage to the waste that inevitably occurs when mixing & with cement-based products, and then rounds the result to the nearest full 20 kg bag. Therefore, 74 to 60 lb or 56 to 80 lb or 112 to 40 lb concrete bags will be required for a 10×10 slab with a 4″ thickness. With a 5-inch thick slab, 1.54 cubic yards or 42 cubic feet or ready-mix concrete bags of 93 to 60 lb or 70-80 lb will be needed, and with a 6-inch thick slab, 1.85 cubic yards or 50 cubic feet or concrete bags of 112 to 60 lb or 84-80 lb will be required.

Regardless of size, you must calculate the volume of concrete in cubic yards before ordering mixed concrete. We know that measurements can be a real pain when **placing concrete**, and if not done correctly, the results may be far from expected. So far, we've covered how to calculate yards, but if your project is small, you can use pre-mixed bags of concrete. At a thickness of 4″, for a 10×10 slab, you'll generally need 1.23 cubic yards or 33 cubic feet or ready-mix concrete bags of 74 to 60 lb or 56-80 lb.

The weight of concrete is determined by its density, which can vary depending on the amount of aggregate, water and air in the mixture. Ready mix concrete made of mixed mix of Portland cement, sand and other approved ingredients, generally, dry ready-mix concrete is available in different bag sizes and weight conditions, such as 40 lb bag, 60 lb bag, 80 lb bag, 90 lb bag, etc.
