A cinder block with 4 inch size weighs about 15 to 26 pounds while that of a size 6 inches weighs 28 to 32 pounds. Bigger cinder blocks like 8 inches weigh 35 to 40 pounds, 10 inch size weigh 43 to 55 pounds while 12 inches size weigh 58 to 62 pounds. The largest cinder block of 16 inches size has a maximum weight of 72 pounds.

But how much does a cinder block weigh in absolute pounds rather than a maximum and minimum range? Well, that’s why I’ve written this blog and for that you need to continue reading the entire article. Make sure to not skip any information on this page.

The sizes I’ve explained in the opening paragraph are the standard sizes of cinder block. The height and depth of standard CMU cinder blocks are typically 8×8 inches. While the length of the cinder block varies from 4 inch up to 12 inches.

Details about cinder block weight

Explore the factors that affect cinder block weight and understand how to calculate it accurately.

CMU is abbreviated as concrete masonry units or concrete blocks are widely used building material and have diversified field applications. A mixture of Plain Cement Concrete constitutes the formation of rectangular blocks. These blocks are valuable due to their durability, strength and versatility.

Cinder Block Types

Standard Cinder Blocks

The standard cinder blocks are grey in color and available in different sizes. These blocks contains hollow core inside which later on to be filled with steel and concrete during their placement. These hollow cores make them lighter and due to reduction in weight these are easy to transport during construction

Lightweight Cinder Blocks

These blocks are light weight as compared to standard blocks because of use of light weight aggregates. They are manufactured using lightweight aggregates, such as expanded shale or clay, which reduces their overall density. These blocks gain popularity and ideal for construction due to reduced weight e.g. in the load bearing wall.

Split-Faced Cinder Blocks

The standard cinder block alternative is Split faced cinder blocks which gives an appealing and aesthetic look to building.

These blocks have a rough texture on one or both sides, achieved by splitting the block during the manufacturing process. The rough texture provides a natural stone-like appearance, making split-faced cinder blocks a popular choice for decorative purposes, including exposed walls, retaining walls, or landscaping projects.

Decorative Cinder Blocks

To enhance the aesthetic look and architectural beauty, decorative cinder blocks are used e.g. garden features, decorative walls and fences etc. these are also available in different shapes and sizes and their incorporation increases the visual look to structure.

Concrete Masonry Units (CMUs)

Concrete Masonry Units (CMUs) refer to a broader category of masonry blocks, which includes cinder blocks. CMUs are available in various types, sizes, and finishes, catering to different construction requirements. While cinder blocks are a specific type of CMU, it’s essential to understand the broader context of CMUs to fully grasp the options available for construction projects.

Concrete masonry unit in short form represented as CMU made of concrete, mixture of cement, sand and water or industrial wastage. There is a form of concrete masonry unit cinder block, concrete bricks, hollow cinder block, solid concrete block, lintel block, concrete stretcher block, concrete pillar blocks, partition concrete block, corner concrete block, and concrete pillar block.

Concrete Masonry Units (CMUs)

How much does a cinder block weigh?

Depending upon the application, it is used in construction industry a typical 2 core cinder block weighs about 38 Ibs (17 Kg) of size 8 x 8 x 16 inches hollow. The weight of 17 Kg represents the dry weight. The 02 hollow cells are filled with concrete and rebar. Depending upon the size, capacity and overall project dimensions the weight may vary.

Similarly, 76 Ibs (34 Kg) represents a typical solid core cinder block having dimensions 8 x 8 x 16 inches. 6 Kg (14 Ibs) represents the size of 8 x 8 x 8 inches. 25 Kg (55 Ibs) represents the size of 12 x 8 x 8 inches.

How much does a cinder block weigh?

As per the United States practice and based upon light, medium and heavy weight conditions a typical cinder block having dimension 8 x 8 x 16 inch weight between 28-35 Ibs. It depends upon the density and size of cinder block as the most common size is 16 x 8 x 8 inches (length x height x width).

Different sizes of Cinder Block

The different sizes are given below:

  • 4 x 8 x 16 inches / 101 x 203 x 406 mm correspond to weight of 14-18 Ibs.
  • 6 x 8 x 16 inches/ 152 x 203 x 406 mm correspond to weight of 21-26 Ibs.
  • 8 x 8 x 16 inches/ 203 x 203 x 406 mm correspond to weight of 28-35 Ibs.
  • 10 x 8 x 16 inches/ 254 x 203 x 406 mm correspond to weight of 35-44 Ibs.
  • 12 x 8 x 16 inches/ 305 x 203 x 406 mm correspond to weight of 42-53 Ibs.
  • 8 x 8 x 8 inches/ 203 x 203 x 203 mm correspond to weight of 14 Ibs.

The sizes mentioned above are the nominal sizes but for standard sizes or workable sizes subtract a mortar thickness of 3/8 inch. For instance, the nominal dimension of 4 inch cinder block is 16 x 4 x 8 inches, but the standard size will be 15*5/8 x 3*5/8 x 7*5/8 having weight of 14-18 Ibs. The density of good quality cinder block is 0.054 Ib/in3 and have a volume of 512 in3. As we know that density is obtained by dividing mass by volume. In this context while multiplying 512 with 0.054 gives you weight of cinder block that comes to be 14-18 Ibs.

Conclusion:

As per ASTM specifications, different sizes are available for cinder block size. They are represented by their nominal size includes the thickness of mortar i.e. 3/8 inches and the standard size is always less than the nominal size.
