Concrete masonry units (CMUs), commonly known as concrete blocks, were invented in the late 19th century. The first patents for concrete block machines were filed in the 1830s, but they gained widespread popularity in the early 1900s, particularly after the introduction of reinforced concrete technology. Their use became more prevalent in construction during the 20th century, as they offered a durable and cost-effective building material.

What is the cost of one Concrete Masonry Unit?
The cost of one Concrete Masonry Unit (CMU) typically ranges from $1 to $5, depending on factors such as size, type, and local market conditions. Specialty blocks, such as those with insulation or decorative finishes, can be more expensive. To get an accurate price, it's best to check with local suppliers or manufacturers. Additionally, bulk purchasing can often lead to discounts.
What is the difference between burnt clay masonry and concrete masonry?
Burnt clay masonry is made from fired clay bricks, which offer good thermal insulation and aesthetic appeal, while concrete masonry consists of concrete blocks that provide structural strength and durability. Burnt clay bricks are typically lighter and can be used in various architectural styles, whereas concrete blocks are often favored for their load-bearing capabilities and resistance to weathering. Additionally, the production processes differ, with burnt clay requiring firing in a kiln, while concrete masonry is cast and cured. Overall, the choice between the two depends on the specific requirements of a construction project.
What is the difference between brick veneer and brick masonry?
Masonry implies bricks, blocks, or stones held together with mortar. Bricks are fired ceramic. Blocks are usually formed concrete. And stones are formed naturally and quarried from the earth. They are held together with mortar. Concrete is used as mortar, but concrete can also be poured to make slabs and foundations. I think the difference is that concrete can be used by itself without being considered masonry. For example, even statues can be made from concrete by pouring them into a mold.

What is the u-value of a 200mm thick hollow concrete masonry unit?
The U-value of a 200mm thick hollow concrete masonry unit typically ranges from 1.0 to 1.5 W/m²K, depending on factors such as the density of the concrete, the size and shape of the cavities, and any insulation used. For more precise calculations, it is important to refer to specific material data sheets or conduct thermal performance assessments based on the actual masonry unit in question.
