Cinder Block Vs 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.
What Is Cinder Block?
Cinder blocks are made of hollow rectangular-shaped structures. Which are usually made using concrete and burnt coal. Cinder blocks are shaped similarly to concrete blocks.
Concrete and cinder blocks are often made by the same basic process. But there are cinder blocks made using a special material made for various special functions.
Cinder blocks are also made by mixing coal cinders in a concrete mix. Cinder blocks are lighter in weight than concrete blocks. Cinder blocks are made like hollow concrete blocks.
They are not particularly strong as they are made of coal dust, so they are always avoided in some places.
Specification of Cinder Block
- They cannot be used in a place like a turn.
- Cinder block increases water absorption.
- The cinder block is the result of a mixture of coal dust and concrete.
- Repairs done with cinder block are very expensive so it is avoided.
- Cinder blocks were used in wooden framed doors and windows. In addition, cinder blocks were used in decorative opening doors for structures.
- The tensile strength of the cinder block are less.
- In the old days, people used to make this type of block using industrial waste. Now, this type of block has become extinct for almost 50 years.
History of Cinder Block
Large coal-fired power plants and steel mills were producing coal waste every day. So the people there used it to make ‘cinder blocks’. They were made of concrete blocks shape.
But in cinder block, coal cinders or ash is mixed with concrete. As a result, the weight of cinder blocks becomes lighter than that of concrete blocks.
In the villages, people used this cinder block in the compound wall.
How Much Does a Cinder Block Weigh?
Standard Cinder Block Weighs 38 lb. / is 17 kg. Its standard size is 8 inches x 8 inches x 16 inches. Cement and aggregate are used to create a cinder block. It may be industrial waste, fly ash, coal ash, recycled material, slag cement or recycled overall, etc.
Therefore, cinder blocks are lightweight. It is sometimes designed as a low-density block. 12 inch x 8 inch x 16 inch hollow cinder block weighs 52 lb. / 23.5 kg.

What Is a Concrete Block?
Concrete blocks are made using lightweight aggregate, cement, and sand in appropriate proportions. Sand passing through a 4.75 mm sieve is used for concrete blocks. Aggregate is used to pass through a 12.5 mm sieve.
Concrete blocks are made in the required shapes and sizes and these can be solid or hollow blocks. The normal size of concrete blocks is 30 cm x 20 cm. x10 cm In addition 2 inches, 4 inches, 6 inches, 8 inches, 10 inches, and 12 inches are made as required.
Concrete blocks are mainly used in the construction of walls in high-rise buildings. A concrete block is also called a concrete masonry unit. A concrete block is one of the many precast concrete products used in construction.
The term precast implies that blocks are made before they are brought to the site and brought to the site only after sufficient strength has been obtained. Cavities are found in most concrete blocks, and their sides are cast with design.
Concrete blocks are prepared by mixing cement, aggregate, and water in appropriate proportions. The cement-aggregate ratio in concrete blocks is 1: 6.
50% coarse aggregate and 50% fine aggregate are used in making concrete blocks. The minimum strength of the concrete block is 2.8 N / mm2.

11 Type of Concrete Block
Different types of concrete blocks are provided based on their composition, shape, size, and production processes. which are mainly divided into 2 types,
- Solid Concrete Block
- Hollow Concrete Block
1. Solid Concrete Block
A solid concrete block is used in the building where load-bearing walls are to be constructed. A solid concrete block is stronger than a hollow concrete block. It transfers the load on the foundation and helps to provide stability to the structure.
Solid concrete blocks are widely used in the market. The aggregate of good quality is used in solid concrete blocks.
Solid concrete blocks are available in different sizes in the market. Its size is bigger than brick. Masonry work of solid block takes more time.
Good finishing is obtained from a solid concrete block.
2. Hollow Concrete Block
Hollow concrete blocks have a hollow area of more than 25% of the total area. The solid area in a hollow concrete block should be more than 50%. The hollow part is made in many parts depending on the need. The hollow concrete block has a lightweight aggregate, sand, and water mix ratio.
There are different types of hollow concrete blocks depending on the need.
- Concrete Corner Block
- Concrete Piller Block
- Concrete Strecher Block
- Partition Concrete Block
- Jamb Concrete Blocks
- Frogged Brick Blocks
- Bullnose Concrete Block
- Paver Block
- Lintel Block
3. Concrete Corner Block
Concrete Corner Blocks The name of this type of block indicates that the space of the corner is fixed. This block is typically fixed in place of window and door. This block has a surface finish type.
4. Concrete Piller Block
Concrete pillar blocks are designed in such a way that they are kept on both sides of the surface plane. For the same reason, it is also known as double corner blocks. It is used for pillars. It is also used in making cable trench.
5. Concrete Strecher Block
This type of block is used to join the wall. It is especially used where the RCC column is located
6. Partition Concrete Block
This type of block is used to form a partition wall, which is typically used to divide a room.
It can be used in elevation.
7. Jamb Concrete Blocks
This type of block is used done in the window. It is used with stretcher block.
8. Frogged Brick Blocks
This type of block is used where the load-bearing walls are located. This type of block is used to increase the strength of two layers.
9. Bullnose Concrete Block
This type of block is used for elevation where the corner comes.
10. Paver Block
This type of block is used to make a pathway in a building. it is also used in parking spaces in the building.
11. Lintel Block
This type of block is used in windows and doors.

Cinder Blocks Vs Concrete Blocks
Cinder block is made of- concrete and coal cinders. Concrete block is produced from steel, wood, and cement. Cinder blocks are lighter than concrete blocks. A concrete block contains stone or sand which makes it heavier.
What Is the Difference Between Cinder Block and Cement Block?
Cinder block is made of- concrete and coal cinders. Concrete block is produced from steel, wood, and cement. Cinder blocks are lighter than concrete blocks. A concrete block contains stone or sand which makes it heavier.
Concrete Blocks Vs Cinder Blocks Foundation
Poured concrete walls are free from joints and are much denser than cinder block foundation walls. They will not give in as quickly to buckling or bowing. Poured concrete walls have the highest fire safety rating when compared to cinder blocks. Poured concrete walls offer more design flexibility for builders.
What Are the Dimensions of a Cinder Block?
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).
Cinder Block Vs Concrete Block Retaining Wall
They are similar in shape and construction to concrete blocks, but instead of sand or gravel, much of the aggregate filling material is coal cinder. Compared to concrete, cinder blocks are much lighter in weight. They are much easier to work with, but being lighter also decreases their pressure-bearing ability.
Cinder Block Vs Concrete Block House
Cinder block is lighter than concrete blocks. Concrete block is heavier because it contains stone and sand. Cinder block does not have the strength to withstand high pressure. Concrete block is a hard building element with high strength.
Which Is Stronger Cinder Block or Concrete Block?
Concrete and cinder blocks are produced with open cells that can accept metal reinforcing or additional concrete for higher resistance. Concrete blocks are far stronger than cinder blocks. Several building codes explicitly prohibit the use of cinder blocks in building and construction projects.
What Is Concrete Block Size?
Common dimensions of cinder blocks are 8-by-8-by-16 inches. However, like most boards, their actual sizes are different from labels. Most cinder blocks are smaller. Their actual dimensions are more apt to be 7 5/8-by-7 5/8-by-15 5/8.
How Tall Is a Cinder Block?
Cinder blocks typically have standard dimensions, including height, width, and length. The standard height of a cinder block is 8 inches (20.32 centimeters). However, it’s important to note that there are variations in block sizes, and some manufacturers may produce cinder blocks with slightly different dimensions.
How Big Is a Cinder Block?
Cinder blocks, also known as concrete masonry units (CMUs), have standard dimensions that are widely used in construction. The typical size of a cinder block is 8 inches (20.32 centimeters) in height, 8 inches in depth or width, and 16 inches (40.64 centimeters) in length. These dimensions are commonly referred to as an 8x8x16 cinder block.
How Much Do Cinder Blocks Cost?
Cinder block walls cost about $10 to $30 per square foot for the materials, like blocks and mortar, plus professional installation. The materials cost about $3 to $6 per square foot.
How Much Does Cinder Block Weigh?
The standard 8 x 8 x 16 concrete block weighs around 38 pounds on average (15.88-17.24 kg).
