The dry weight of a medium density concrete block (215 x 450 x 100mm thick) is approximately 7.5Kg
---
There are many different sizes, shapes and mixes used to make concrete block.
Additionally the weight varies if the unit is wet or not since they absorb water.
I see varying weights of 35 to 55 pounds for 8x8x16 block.
15 pounds
13.4kg approximately
A standard 8x8x16 2 core block contains about .25cf of open space
There are 10 concrete block per m2.
A concrete block is made from concrete, a brick block is made from brick. They are two different building materials. Both have their respective advantages and disadvantages.
what is the weight of concrete block work per cubic meter.
In America: 8x8x16 inches, This is the standard CMU: Concrete Masonry Unit There also the half blocks 8x8x8. Source: http://concreteblocksizes.blogspot.com/
There are a few different types of masonry work. The types of masonry work are veneer, dry set masonry, solid masonry, brick masonry, concrete block, a-jacks, stonework, gabions, and bagged concrete.
It weighs 59 lbs. There is a difference between a "real" cinder block and a concrete block. A cinder block uses cinders--ash from the burning of coal--as its aggregate. Concrete blocks are made from concrete. Concrete block is far stronger than is cinder block, and some jurisdictions prohibit the use of cinder block. The only justification for cinder block is that it weighs less than concrete block, which is important if the ground you're building on isn't strong enough to support a heavy structure. This justification has gone away, because now you can buy concrete block made from expanded-shale aggregate that's as light as cinder block and as strong as standard-weight concrete masonry.
finished out dimensions are 8"x8"x16" basic dimensions of a concrete block are 7-5/8"x7-5/8"x15-5/8"
It depends on the application. For homes, masonry is fine as long as it is insulated well against the weather. Masonry rarely needs maintenance. Concrete walls are stronger and last longer than masonry but are more costly to construct. For basement walls, I suggest that you always use concrete walls. Above ground level, masonry is cheaper and strong enough for residential and commercial, multi-story applications. For retaining walls, 8" thick masonry works well up to about 8 feet of retained earth. Above that, the lower courses of block will get thicker to 12". You still need concrete footings for block walls.
Rebar: The steel rods that are sued to reinforce concrete or masonry (bricks or concrete block).
With a masonry chisel. It may be easier to cover it with a new surface.
Without the size opf the block, if is not possible tell the weight,
Rebar is used to give strength to masonry and concrete constructions. Masonry is this case is concrete blocks. Concrete, block or cast in place, is good for compression forces and not tension. Steel is good in tension or tensile forces and not compression. By combining the constructive elements of concrete with steel, thus reinforced concrete, you get the strengths of both in one medium.
2400Kg/cu.m
The standard concrete building block for load-bearing walls is 8 x 8 x 16
