Standard Concrete Cinder Block - Construction & DIY Building Material #1663284 (License: Personal Use)

This is a standard 8-inch × 8-inch × 16-inch concrete masonry unit (CMU), also known as a cinder block, featuring two rectangular voids that reduce weight while maintaining structural integrity. The aggregate-rich surface shows fine gravel and sand particles, indicating high compressive strength and durability for load-bearing and non-load-bearing applications. It rests on a poured concrete slab, typical of construction staging or material prep areas.

Used on construction websites, building supply catalogs, DIY project guides, and contractor resource pages; matches user intent for purchasing, comparing specs, or learning about masonry basics.
