yes it is because there are more than mixtures in concrete example there is water in concrete so yes the there are more than 2 substances thatis mixed so a concrete block is a solution.
A breeze-block is a lightweight building block made from cinders and concrete.
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.
The standard concrete building block for load-bearing walls is 8 x 8 x 16
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.
While concrete has been used as a building material for many centuries, concrete hollow blocks have only been manufactured since the early 1900s. These blocks are used in all types of building projects.
