For every m2 of wall you will need ten concrete blocks. For every ten blocks you will need two 25kg bags of bricklaying mortar. If you are working on a larger project it may be more economical to mix your own mortar. For bricklaying you need to mix one part of cement to five parts building sand.

A 60-pound bag yields . 017 cubic yards, and an 80-pound bag yields . 022 cubic yards. For a 10 x 10 slab, you would need 77 60-pound bags or 60 80-pound bags.

Typically, 1m3 of concrete is made up of 350Kg of cement, 700Kg of sand, 1,200Kg of chippings and 150 Litres of water..

For a 10 x 10 slab, we'd suggest a mix with a capacity of about 4,000 pounds per square inch, or psi. This is basic for residential projects, and it can withstand traffic and support heavy loads.

Each hole for the terminal posts must be 8 inches in diameter and 30 inches deep, requiring 0.85 cubic feet of concrete to fill.

You do not need rebar for any slab if you make it thick enough and space the joints properly. Rebar in jointed pavement is there to counter the cupping effect of thermal expansion. I always recommend the use of rebar or at least rewire. Any concrete slab can crack.

12,000 pound two-post lifts (and higher capacity): Six (6) inches of concrete at 3000 PSI is required.

10 x 10 = 100 square feet. 4 ÷ 12 = .33. 100 x .33 = 33 cubic feet. 33 x .037 = 1.22 cubic yards.

Once you know how big the room is and ideally know how many square meters are in it, you can simply divide that figure by 9 to give you about how many bags of multi finish plaster you will need. Multi finish covers 10m2, but I say 9m2 to all allow for wastage.

To plaster 100 square metres (15 millimeters thick) you will need: 14 bags cement + 2,25 cubic metres sand. Using masonry cement complying with SANS 50413 class MC 12,5X. To plaster 100 square metres (15 millimeters thick) you will need: 20 bags cement + 2 cubic metres sand.

In most cases a 50-pound bag of quick-dry concrete should suffice. Saturate the concrete. For a 50-pound bag you will need about a gallon of water. Be sure to leave support beams in place for 4 to 6 hours or until concrete is dry.

For a 10 x 10 slab, you would need 77 60-pound bags or 60 80-pound bags. If we add an extra 10%, that's an extra 8 60-pound bags or 6 80-pound bags.

Mortar calculation for tile flooring We need 1.5 m3 volume of wet cement mortar that means, we need this much volume after adding water to cement and sand mix. Dry volume of mortar is considered as 25% of more of wet volume.

Enter the size of the slab you want to build in square feet. The calculator will indicate the number of 60 or 80 pound bags of QUIKRETE® Concrete Mix you need to build a 4″ or a 6″ slab. (All yields are approximate and do not include allowance for uneven subgrade, waste, etc.)

Each 80-pound bag of QUIKRETE(r) Concrete Mix will yield approximately 0.6 cubic feet of concrete. For a 10' by 10' slab at 4" thick, you will need 33-1/3 cubic feet of concrete, or 56 80-pound bags. Yields are approximate and will vary with waste, uneven subgrade, etc.

Using a Concrete Calculator You'll also get the number of 40-pound, 60-pound, or 80-pound bags of concrete are needed for the project. For example, a 10′ x 10′ slab that is 4″ thick will need an estimated 1.23 yards3 or 75 60lb bags of concrete and will cost roughly $140.

The volume of concrete required for a 10- by 10-foot slab depends on the diameter of the slab.

The use determines the thickness. So if you take the surface area and multiply it by the thickness you will get the volume. Ie. 40 feet × 60 feet × 1 foot thick would be 2400 cubic feet of concrete divide by 27 to get cubic yards 2400÷27= 88.889.

A typical concrete slab will cost between $113 and $126 per cubic yard (27 cubic feet) or $5.35 to $6.17 per square foot on average.
