Concrete blocks are a form of construction material composed of concrete, cement, sand, water, and other additives. They are used in different types of construction applications. There is a common misconception that concrete blocks are mainly useful for controlling traffic in the form of large concrete barriers.
Why are concrete blocks used in traffic?
Concrete blocks are an incredible source of vehicular traffic control, too. Large blocks can be lined up side by side to organize traffic. Concrete blocks are designed in a variety of ways to make them adaptable to different applications and contexts.
How thick are aerated autoclaved concrete blocks?
Aerated autoclaved concrete blocks come in lengths of 24, 32, and 48 inches. Their thickness varies from four to 16 inches, whereas their height is typically eight inches. As these concrete blocks are much more versatile than their standard concrete block counterparts, they are used in the construction of walls, roofs, and floors. Besides being strong and fire-resistant, aerated autoclaved concrete blocks are excellent for both sound and thermal insulation. However, to ensure maximum longevity, they must be coated using an applied finish such as a polymer-modified stucco, finished with a siding, or covered with a natural or engineered stone.
Why are concrete blocks in demand?
Concrete blocks are in demand due to their compressive strength that’s common in all the types. There are numerous methods in place to estimate the concrete’s strength as well as to ensure whether the manufactured concrete meets the standard strength requirements.
How do manufacturers reduce the density of concrete blocks?
When manufacturers aim to produce blocks with high heat-insulating properties, they reduce the concrete block density by volume and generate low-weight blocks. Furthermore, the insulating properties of a concrete block wall can also be increased through solid grouting of the cells.
What is the difference between solid concrete and concrete bricks?
Solid concrete blocks are among the most commonly used concrete blocks that are way bigger and denser than concrete bricks. They are designed to be heavy, strong, and are produced from naturally dense aggregates. Due to their strength, they are mostly used for building load-bearing walls and structures. Although they are similar to concrete bricks, it’s their weight and cost that distinguishes them from concrete bricks. Also, their larger size means that they lead to quicker construction of a structure as compared to bricks.

What is rowlock brick?
They were similar in size to concrete blocks used as backup above grade in solid masonry walls. There would be a brick facing. The bricks would be laid every 6 th course lengthwise across the block to tie in the wall. On the wall face you would see the small end of brick. This was called a rowlock. It was not very strong & darker in colour than normal conc. Block. Homes aren’t built like this anymore for cost & insulating reasons. The system was a nightmare for electrical/plumbing etc. For many yrs. Exterior walls had a
