In the US, CMU blocks are
nominally 16 in (410 mm) long and 8 in (200 mm) wide
. Their actual dimensions are 3⁄8 inch (9.5 mm) less than the nominal dimensions (to allow for 3⁄8-inch mortar joints between blocks in any orientation).
What is the size of a concrete block?
| CMU Size Nominal Dimensions D x H x L Actual Dimensions D x H x L | 6′′ CMU Full Block 6′′ x 8′′ x 16′′ 5 5/8′′ x 7 5/8′′ x 15 5/8′′ | 6′′ CMU Half-Block 6′′ x 8′′ x 8′′ 5 5/8′′ x 7 5/8′′ x 7 5/8′′ | 8′′ CMU Full Block 8′′ x 8′′ x 16′′ 7 5/8′′ x 7 5/8′′ x 15 5/8′′ | 8′′ CMU Half-Block 8′′ x 8′′ x 8′′ 7 5/8′′ x 7 5/8′′ x 7 5/8′′ |

What is the size of a standard block?
Blocks are produced in a broad range of sizes, but for general building work the most commonly used is referred to as a standard block and measures
440mm x 100mm x 215mm
(see Figure 2). Usefully, this is the same length as two bricks and the height of three bricks with 10mm mortar joints.
What is the actual size of a 200 mm concrete block?
In 1979, the industry switched to metric sized blocks based on the following dimensions – height of 200 mm, length of 400 mm, width ranging from 100 to 300 mm. After accounting for 10 mm of mortar, the actual dimensions of the blocks are
190 mm by 390 mm by between 90 and 390 mm.
How do I calculate concrete blocks?
After you have found the square footage of both your wall and your block, determining the number of blocks you need is as simple as
dividing the wall square footage by the block square footage
. If you’re using a standard 16′′ x 8′′ x 8′′ block, find the number of blocks needed by dividing the wall square footage by 0.89.
How do you calculate the number of blocks?
Measure the length and height of the block in inches and then substitute the values in the equation
square feet of block = (length of block x height of block) / 144
. For example, a standard cement block measures 16 x 8 inches, so it covers 0.89 square feet — (16 x 8) / 144 = 0.89.
How much does a 12 inch concrete block cost?
| Block width (inches) Average cost per block | 12 ” $2.00 – $4.00 |

What are the different types of concrete blocks?
- Concrete Bricks.
- Solid Concrete Blocks.
- Aerated Autoclaved Concrete Blocks.
- Concrete Stretcher Blocks.
- Concrete Pillar Blocks.
- Concrete Corner Blocks.
- Partition Concrete Blocks.
How much are concrete blocks?
While some capstones can cost as little as $0.95 apiece, the average cost of a cinder block is
$1 to $3 each
. The total cost of building a cinder block wall ranges between $9 and $12 per square foot with labor, so an 8 x 15-foot wall would cost between $1,080 and $1,440.
What is the difference between a cinder block and concrete block?
Cinder blocks are hollow rectangle-shaped structures usually made of concrete and coal cinders which find use in construction sites. Concrete blocks often, on the other hand, are flattened constructs made of steel, wood or cement.
How thick is a brick?
How thick is a brick inches? The standard dimension of a modern brick is 215 × 102.5 × 65 mm
(approximately 8 5⁄8 × 4 1⁄8 × 2 5⁄8 inch)
, with a nominal 10 mm (3⁄8 inch). The mortar joint makes a unit dimension of 225 × 112.5 × 75 mm (9 × 4 1/2 × 3 in) for a ratio of 6 × 3: 2.
What are concrete blocks used for?
Today, the immense versatility of concrete blocks is demonstrated in their use throughout a building from its foundation walls, through cavity walls, monolithic walls, partition walls, separating walls and
as a component of ‘beam and block’ flooring
.
How many blocks are in a cubic meter?
In 1 Cubic Meter contain
158 Block
.
How many blocks can build a 3 bedroom flat?
Hence, the total number of blocks required to take the building from lintel level to roof level = 67.6728 × 10 = 676.728 = 677 blocks (disregarding damages and wastage). Ultimately, the total number of blocks required to complete the construction = 903 + 1452 + 677 =
3032 blocks
(disregarding wastage).
Do you fill concrete blocks with concrete?
Whenever you are working with cinder block,
you can strengthen them significantly by filling them with concrete
. … You can make up the difference by spending a little more to reinforce the blocks, a project that is still less expensive than using just poured concrete.
How many bags of cement do I need for 100 blocks?
Three bags
of mortar are estimated for every 100 block, therefore 6-3/4 bags of mortar are needed ((225 block x 3 bags mortar) / 100 block = 6-3/4 bags of mortar).
