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 egg laying block machine, which occurs via drying under controlled conditions. Then the blocks are cured for up to two weeks before being used.
