Although similar in name, cinder blocks and concrete blocks are usually used for different purposes. The term “cinder block” refers to a small block made with filler materials and are typically less expensive than concrete blocks. Cinder blocks normally have a rectangular shape with a hollow interior which limits their strength and overall usage. Our concrete blocks are made from recycled concrete with a strength rating of 3,000 – 4,000 PSI. Their strength and size options make them perfect for permanent or temporary outdoor solutions for restaurants, special events, job sites, and so much more.
Concrete blocks have a variety of different names and may be referred to as cinder blocks, jersey barriers, breeze blocks, CMU blocks, concrete bin blocks, or masonry blocks. While concrete and cement are not the same things, they’re often used interchangeably, so you may find concrete blocks are occasionally called cement blocks.

Concrete blocks from Ozinga are developed using 100% recycled materials. After mixing concrete, it must be poured. For any project that doesn’t use a full load of prepared concrete, there are leftovers that must be used. Ozinga makes sure this material doesn’t go to waste by pouring concrete blocks using the leftovers.
