How much concrete do I need calculator?

For laying bricks and blocks in normal applications (SABS Class II) To lay 1000 bricks = 3 bags cement + 0.6 cu. m. sand.

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.

For concrete, the formula for volume is as follows: length x width x thickness. To determine how many bags of concrete you will need, divide the total cubic yards needed by the yield. Use the following yields per each bag size: 40 pound bag yields .011 cubic yards.

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

With a brief look, a 20x20 area at 6 inches deep, you would need approximately 10.52 tons or 7.41 cubic yards of gravel. Concrete reinforcing is also recommended in high traffic areas and medium to large areas.

Multiply the width times the length times the height (W x L x H). You can also use our volume calculator to find cubic yardage of a space. Convert the volume to cubic yards from cubic feet. To do so, divide the cubic footage by 27 to get the yards of concrete needed.

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

For concrete, the formula for volume is as follows: length x width x thickness. To determine how many bags of concrete you will need, divide the total cubic yards needed by the yield.

Beside above, how much crushed concrete do I need calculator? In the construction world, most materials are measured in cubic yards. Multiply the length (L), in feet, by the width (W), in feet, by the height (H), in feet, and divide by 27. This will tell you how many cubic yards of crushed stone you need.

Concrete blocks are much easier to calculate. Each block is 450 x 215 x 100. Ten blocks will construct approximately 1 square meter of wall, with 1 bag of sand/cement mix enough for 10 blocks.

How Much Does It Cost to Pour A 12×12 Concrete Slab? It would cost $11,520 to pour a 12m x 12m concrete slab according to a calculator estimate. However, the total cost of a project may reach up to $30,000.

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.

As to how many bags....a 55 gallon drum filled clear to the top is actually closer to 60 gallons. And 60 gallons is 8 cu ft. So if you buy 60lb bags, those do 1/2 cu ft each so you would need 16 of them. IF you buy 80lb bags (2/3 cu ft) you would need 12 bags.

For example, a sono tube with a 10" diameter and a 4' depth requires 0.08 cubic yards of concrete..

The depth of the hole should be 1/3-1/4 the post height above ground (i.e., a 6-foot tall would require a hole depth of at least 2 feet).

Plan on at least 5 minutes per cubic yard, for unloading time. How much concrete do I need? Order this much concrete, for these standard pool sizes. 12 x 24 – 5 yards, 14 x 28 – 6 yards, 16 x 32 – 7 yards, 18 x 36 – 8 yards and a 20 x 40 – 9 yards.

In order to have enough concrete for one cubic foot, you'll require 2.2 bags of 60-lb concrete.

Since bags are only sold in whole (not half, or quarter) quantities, you'll need to purchase three (3) 60-lb.

bags for one cubic foot..

Remember, the depth of the post hole should be one-half of the above-ground post height.

(Example: For a 6 feet above ground post, use a post with an overall height of 9 feet and place 3 feet in the ground).

The calculator will indicate the number of 50 lb.

bags of QUIKRETE® Fast-Setting Concrete you need..

Multiply the square footage by the depth in feet to find the volume of the space in cubic feet. Volume is found by measuring length × width × depth. Finally, divide the cubic footage by 27 to find the volume in cubic yards. This is the amount of concrete needed.

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.

If there is a layer of water across the top, you've added too much. The rule of thumb is about 5 pounds of water to an 80 pound bag of concrete mix.

Various instructions and regulations therefore also state that you need about 56 packs of dry concrete of 40kg each for 1m³, which results in about 17.86 litres of liquid concrete per pack.

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.

To calculate how much concrete you need, you need to know the post size you are going to use and how many posts you are installing. Your post diameter and height determine how big each hole needs to be. As stated above, fence post holes should be 3 times the diameter of your post and 1⁄3 as deep as your post.

Each 80 lb (36.3 kg) bag of QUIKRETE® grout will fill the cores of approximately 3 standard 8" × 8" × 16" (203 × 203 × 406 mm) block.

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.)

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.

To determine how many bags of concrete you will need, divide the total cubic yards needed by the yield. Use the following yields per each bag size: 40 pound bag yields .011 cubic yards. 60 pound bag yields .017 cubic yards.

1 Cubic Meter of Concrete 1m3 of concrete = 150l water + 250kg cement + 700kg sand + 1200kg aggregates.

For bricklaying you need to mix one part of cement to five parts building sand. It does not matter how you measure a part, be it by weight or by the bucketful, so long as you use the same means of measuring for both sand and cement.

The mixing ratio is 1 part cement and 5 parts sand, and if the plaster is too harsh, 0.5 to 1 part of lime can be added.
