concrete blocks
Heavy gray rectangles
Concrete blocks are rectangular building units made from cement, aggregate, and water, cast in molds and cured until hard.
They're a staple of construction—used for foundations, walls, and structural support.
The hollow-core variety reduces weight while allowing reinforcement with rebar and mortar: We stacked concrete blocks for the retaining wall.
Also called cinder blocks or concrete masonry units (CMUs).
