Quick Summary

A concrete block is a hollow building unit made of concrete, also known as a cement block. Masonry is the art of building with materials like stone, brick, or concrete blocks. Historically, early humans used piles of stone to create artificial caves, and by the 4th millennium BCE, Egypt developed advanced stonemasonry techniques, exemplified by the pyramids. The Romans invented concrete, which allowed for more economical and faster construction of walls, arches, vaults, and domes. While steel and reinforced concrete became more prominent in the 19th century, concrete blocks continue to be used for vertical wall enclosures and partitions.12
