How to calculate concrete needed to pour a slab?
The best way to calculate how much concrete you will need in cubic yards is to do the following:
- Mark your area that needs concrete and divide it into smaller areas.
- Calculate the volume of your area after determining its shape (see the examples below) by multiplying it with the thickness of the concrete.
- Convert the volume from feet to cubic yards to get a precise number of concrete that you need – in cubic yards.

Alternatively, in some factory settings, concrete is mixed into dryer forms to manufacture precast concrete products such as concrete walls. The process of concrete hardening once it has been placed is called curing, and is a slow process.
Why is concrete mixing important?
Proper mixing is essential for the production of strong , uniform concrete. It involves mixing water, aggregate, cement, and any desired additives. Production of concrete is time-sensitive, and the concrete must be placed before it hardens since it is usually prepared as a viscous fluid.
Calculator Use
Calculate volumes for concrete slabs, walls, footers, columns, steps, curbs and gutters. Enter dimensions in US units (inches or feet) or metric units (centimeters or meters) of your concrete structure to get the cubic yards value of the amount of concrete you will need to make this structure.
