Concrete block is a common building material around the world because it's made from inexpensive raw materials and its manufacture is a straightforward process. Concrete block is a molded product made on machines that range from simple manual models that can make 300 blocks a day to powered automated models in commercial blockyards that make thousands of blocks per day

Originally, block making machines were set up at a job site, made enough concrete blocks to complete the job at hand, and were moved on to the next site. This practice is still followed with small manual machines in underdeveloped countries. In developed countries, blocks are made in commercial blockyards on automated machines and shipped to the job site. Modern block-making machines cover a wide range of types and prices. But they all work on the same basic principles. Wet concrete is poured into block molds and is compressed by tamping. The fresh blocks are freed from the molds and exit the machine for hardening, which occurs via drying under controlled conditions. Then the blocks are cured for up to two weeks before being used.

In developed countries, concrete block machines are highly automated stationary devices used in blockyards to produce thousands of blocks per day. Most models offer computer controlled ingredient blending and block manufacture, allowing a blockyard to produce a great variety of concrete brick and block from a single machine. Because of their automation, these machines can be run with a few as six people. Automated block making machines are produced in the United States, Europe and Asia. These machines incorporate automated batching and mixing of the concrete, automated production of eight to 16 blocks at a time, conveyors and other handling equipment for the finished blocks, and the capability to produce different types of hollow and solid blocks, paving blocks, curbstones and other specialty concrete block products
