The Masonry Calculator contains equations and data used in working Rectangular Slab Circular Slab 5 sided polygon (pentagon) slab DIFFERENT SLAB SHAPES with concrete slabs, walls and piers and footers, bricks, blocks and concrete walls. The formulas in this calculator are generally used to calculate materials needed for slabs of different shapes (e.g. rectangular, circular, or polygons), masonry walls made of poured concrete, brick or block, and columns and peers. It also includes a calculator to compute the delivery cost of bulk concrete. For more comprehensive rebar (reinforcement bar) calculations, see the .
The SLABS tab has the following formulas: (Click on any name)
The Walls, Footers and Columns(piers) tab has the following formulas:
Always consult local building codes for the best answer. However, a guideline for the depth of concrete is as follows:
4” - Home basement floors, farm building floors
4”-5” - Home garage and porches
5”-6” - Sidewalks, barn and granary floors, small sheds
6”-8” - Driveways
The term rebar is short for reinforcement bars, and refers to bars of steel embedded in concrete to improve tinsel strength.
