Portland cement is the most common type of cement used in concrete mixtures. It's made from a combination of limestone, clay, and other materials. The amount of Portland cement needed for a concrete project depends on the desired mix ratio (e.g., 1:2:3 for cement:sand:aggregate).

Thus every time you need to calculate the volume of concrete you need to add the above percentage with dry volume. Wet Volume of concrete = Dry Volume of concrete + 55% of dry volume of concrete or. Wet Volume of concrete = Dry Volume of concrete x 1.55. So whatever volume we get from the above formula, we need to multiply the value with …

How much concrete do I need for a 10x10 slab? The amount of concrete you need for a 10x10 slab depends on how thick it will be. So, for a 4-inch slab you'll need 1.24 cubic yards (56 80lb bags), but a 6-inch slab requires 1.85 yards (84 80lb bags). If your slab is a different size or thickness, use our calculator to determine the amount of ...

The MAIN difference is in the amount of cement used. A cubic yard of concrete, whether it's 3000 psi or 4000 psi, weighs about 4000 pounds (when you include the weight of water). But, there's 511 pounds of cement used to make 1 yard of 3000 psi concrete and there's 624 pounds of cement used to make 1 yard of 4000 psi concrete.
