Concrete Block (CMU) Diagram - Construction Material Guide #49240 (License: Personal Use)

This is an isometric illustration of a standard concrete masonry unit (CMU), commonly known as a cinder block or concrete block. It features three longitudinal hollow cores to reduce weight and allow for rebar reinforcement, a scored face for improved mortar adhesion, and a tongue-and-groove end for precise alignment during laying. The block is typically made from Portland cement, aggregates, and water, cured under controlled conditions for durability.

Used on construction product pages, building material catalogs, civil engineering resources, and DIY guides. Matches user intent for learning about CMU specifications, selecting materials for wall systems, or understanding masonry assembly techniques.
