This table contains the pricing for nationally advertised concrete in different unit sizes.

- Price Survey Date:10/12/21
- Price Survey Online Store: Lowes
- Manufacturer: Sakrete

**Note**: this is a random survey of concrete prices on the Internet. The most common prices are found on the websites of major DIY retailers including Home Depot, Lowe's and Menards. Local prices will vary and may include significantly more or less expensive concrete than listed in this survey.

The **Squared Slab Calculator** has the following functions:

- Slab - Volume, Surface Area and Forms: This computes the amount of concrete, the surface area, the length of the forms and the amount of water needed for a rectangular slab.
- Slab - Weight: This computes the weight of the concrete in a rectangular slab
- Rebar and Concrete in a Rectangular Slab: This computes the length and weight of rebar in a rectangular slab. It also computes the total weight of the slab including concrete, taking into account the concrete displaced by rebar.
- Cost of Concrete Using Bags: This computes the cost of pouring a volume of concrete based on the unit price of a bag of concrete. The user has three options for bag size (80 lb, 60 lb and 40lb)
- Cost of Bulk Concrete: This compute the cost of pouring a volume of concrete by the cubic yard. It also allows for delivery cost based on mileage and pumping costs.

The **Circular Slab Calculator** computes the amount of materials needed for a circular slab with the following functions:

- Circular Slab - Volume, Surface Area and Forms: This computes the amount of concrete, the surface size and the length of the forms needed for a rectangular slab.
- Circular Slab - Weight: This computes the weight of the concrete in a rectangular slab
- Rebar and Concrete in a Circular Slab: This computes the length and weight of rebar in a rectangular slab. It also computes the total weight of the slab including concrete, taking into account the concrete displaced by rebar.

The **Concrete Building Calculator**

- Volume of Concrete in a Poured Foundation - Computes the volume of concrete in a poured concrete foundation (in forms)
- Concrete in a Footer - Computes the volume of concrete for a footer based on the length, width and depth of the footer.
- Concrete in a Footer (Cross Section) - Computes the volume of concrete for a footer based on the length and cross-section area of a footer
- Concrete in a Column or Pier - Computes the volume of concrete in a column based on the radius and height of the column
- Concrete for a Post Hole - Computes the volume of concrete for a post hole based on the size of the hole and dimensions of the post.
