A 8x8x16 cement block weighs approximately 36 pounds (16 kg). That is, concrete blocks are generally about 7 times heavier than their dry weight. Note that this is a weight approximation, not an exact one. Cement blocks are also known as CMU blocks.
How Much Does A Cement Block Weigh
How Do You Calculate The Weight Of A Block
There are two common ways to calculate the weight of a block:
- Using average densities
- Using specific gravity
Average Densities Method
Use this method when you want to calculate a weight based on a certain number of blocks. The average density for concrete blocks is 2400 kg/m3, so multiply the number of blocks by 2400. For example, assume you have 300 8x8x16 concrete masonry units (commonly called 8×8’s). Their dimensions are 0.08 m3 so use the following equation:
300 * 2400 = 720000 (kg/m3) weight of 300 blocks
Specific Gravity Method
Use this method when you know the specific gravity for a certain material and want to calculate an unknown weight. The specific gravity for concrete is typically between 2.25 and 2.35, so multiply the known weight by that number to solve for the unknown. For example, assume you have a 10 feet beam that weighs 20 kips. 1 kip is 1000 pounds, so:
20 * 2.35 = 47000 (lbs/kip) weight of beam.
If you know the weight of an object and want to find its volume, divide the weight by the specific gravity.
Weight / Specific Gravity = Volume (for example: 500 divided by 2.35 = 200 cubic feet)
Difference Between Cinder Block And Cement Block
Concrete blocks and cement blocks differ from cinder blocks in that the materials they are made of aren’t fine-grained. Cinder blocks are made from a material that is basically a mixture of sand and Portland cement.
In contrast, concrete blocks and cements blocks contain coarse aggregate in addition to the Portland cement, coarse aggregate is made up of pebbles or gravel. The larger pieces of aggregate result in a denser, stronger material with a coarser texture.
Cinder blocks are often used as the base level for a raised surface, such as a patio or deck. The coarse texture of cinder blocks is ideal for the base, as they are less likely to be affected by moisture.
Cement and concrete blocks are often used with mortar as the binding agent. They are most commonly found in homes that have been converted for use as commercial buildings, such as bars and other businesses. Their textured surface makes it easy to add a layer of paint or stucco, and their strength allows them to serve as a support structure for the floors.
Cinder blocks are made of cinders or ashes that are heated to form a bock which is used as building material. The cinders are made from coal, shale, limestone or gypsum depending on the type of block being produced.
Cinder blocks are mainly made of fine particles which makes it very easy for the material to form and hold its shape. Solid concrete block and cement block differ from cinder block by the materials they are made of aren’t fine-grained.
Lightweight blocks are increasingly common in the construction industry. Trusting load-bearing structures to Concrete Masonry Unit (CMU) is not new. Today, hollow concrete block is used to build entire buildings. Light weight blocks are used for block wall, floor slabs and partitions instead of red bricks.
Brick Wall VS. Block Wall
The main advantage of a brick wall is its aesthetic value, while the main disadvantage of a brick wall is its high cost. On the other hand, one of the main advantages of a concrete block wall is its low cost, while one of the main disadvantages of a concrete block wall is its low resistance to rot and termite damage.
Brick walls are hand-laid using wedge-shaped, hollow bricks called cinder blocks are pre-formed solid cubes of concrete.
Brick walls are more difficult to build and require an experienced mason, while concrete block walls are less expensive for a homebuilder to install.
Brick walls are more resistant to fire, termites and rot, while CMU block walls are waterproof. As a result, basement foundations are often built with concrete block walls.
Brick walls are more expensive to build, while concrete block walls are cheaper for a homebuilder to install.
You can also use weatherproofing products on brick walls to improve their resistance to water damage, while such treatments are not recommended for concrete block walls.
Brick walls are more common in the northeast and parts of the midwest. They are typically 3, 4 or 8 inches thick and can be built using a variety of brick types or block.
Block walls are more common in the midwest and south. They are typically 8, 12 or 16 inches thick and can be built using a variety of block types or brick.
