ASTM standard cinder block size (4″, 6″, 8″, 10″ & 12″) | Cinder Block Standard Size | Nominal and actual size of cinder block | Dimensions of the CMU block.
Block makers using slag material from fly ash or bottom ash, coal dust, recycling aggregate, fine ash particles after burning coal as aggregate material are known as slag blocks in the United States. Its other name concrete stone is also popular.
In the UK it is known as Briese Blocks, which is a synonym for fly ash, and in the Philippines as Hollow Blocks. In New Zealand and Canada they are known as concrete blocks. In New Zealand they are also called building blocks. In Australia, blocks are also referred to as Besser blocks and Besser bricks, as the Better Company was a major supplier of concrete block making machinery. Clinker blocks use clinker as an aggregate.
Concrete masonry abbreviated as CMU made of concrete, mixture of cement, sand and water or industrial waste such as coal dust, fly ash, recycling material, bottom ash etc. There is a form of concrete masonry made of concrete block brick, hollow cinder block, solid concrete block, lintel block, concrete support block, concrete pier blocks, Separating concrete block, corner concrete block, concrete pillar block.
In the United States, cinder or concrete blocks serve as an economical building material, and there is a wide range of construction uses in many types of residential, public, and industrial buildings. Due to the strong and durable building material, architects and engineers are recommended for home construction, retaining walls, safety barriers, etc. and this is the best choice.
Nominal and actual size of the cinder block
Cinder blocks, which are manufactured in various sizes, are identified by their depth, so the thickness of the wall that creates, for example, 4″ CMU is typically 4″ wide, while 10″ CMU is 10″ wide, represented as depth × height × Length , it is also available in half size, which is helpful in reducing the need to cut cinder blocks on the job site.
The nominal size of the cinder block is the sum of the size of the block and the thickness of the mortar. Cinder blocks are available in many sizes, shapes and dimensions. In the United States, the most commonly used nominal cinder block size is 16 inches long by 8 inches high by 8 inches wide, its actual size measures 3/8 inch shorter, allowing for mortar joints, its actual size is 7 5/8″ × 7 5 /8″ × 15 5/8″.
