Cinder Block | Dimension, Weight, Cost, Advantages & Disadvantages

In this article, we will discuss cinder block.

 

  1. Introduction  

Cinder blocks may be defined as hollow rectangle-shaped structures normally prepared of concrete and coal cinders that are available utilized to build walls in construction sites.

Ash is utilized as aggregate in the cinder block. The difference between Concrete blocks and cinder is that concrete blocks are prepared by using cement, aggregate, sand, water but in cinder, ash is used in place of aggregate.

 

  2. Properties of Cinder Blocks  

a. It is generally prepared of concrete and cinder.

b. It is very light compared to the latter because of the proportion of aggregate

c. It is not very strong, so it is many times neglected in a few places.

d. They are more likely to bend, and buckling and repairs are many times very expensive, so they are neglected.

e. It is the oldest fashion, as they have not been mass-produced for about 50%.

f. It does not have a notable quantity of tensile strength.

 

 

  3. Preparation of Cinder Blocks  

A normal cinder block weight is around 26-33 lb (11.8-15.0 kg). Lightweight concrete blocks are prepared by removing the sand and gravel with expanded clay, shale, or slate. Expanded clay, shale, and slate are made by crushing the raw materials and heating them to about 2000°F (1093°C).

  4. Types of Cinder Block  

 

Standard Gray Cinder Blocks

This format offers strength and durability, fire resistance, excellent acoustic insulation qualities, energy-saving, and affordable price, meets ASTM C-90 specifications.

The common size, such as 8 inches x 8 inches x 16 inches;

 

Concrete Deck Block

It is the very best and economical method for deck construction. This type of block is made for DIY customers. This block allows dimensional wood. In this block, there is no need to mix or pour cinder for the common size, such as 7 “x 11” x 11 “.

 

Standard Core Block

This type of cinder block is used to build cinder walls for large structures, such as buildings, schools, etc. The common size, like 12 in. x 8 in. x 16 in .;

 

Quikrete Concrete Deck Block

This type of block is utilized for deck support and fast and strong construction. The common size, such as 10 in. x 10 in. x 10 in .; Actual: 625 in. x 9.625 in. x 9.625 in.

 

  5. Cinder Block Dimensions  

In the US, Cinder blocks are 16 in (410 mm) long and 8 in (200 mm) wide. Their normal dimensions are 38 inch (9.5 mm) less than the formal dimensions (to permit for ​38-inch mortar joints between blocks in any orientation).

  6. Cinder Block Cost  

Cinder blocks don’t differ more in cost based on the type. While few capstones can cost 95 cents apiece, the normal cost of a cinder block is $1 to $3 each.

 

  7. Advantages of Cinder Block  

a. No dressing work is needed.

b. It is very light in weight.

c. Not much skill required.

d. It is structurally stronger than bricks.

e. Thinner walls are possible, hence providing more carpet area.
