If brick laying is too slow
Cement blocks are much larger. They come
in sizes of wall thickness. They are cast insteel forms and vibrated to increase density
and hardness.
Do not use cement blocks that were not
vibrated. They easily crumble and break.

Tongue and Groove
If tongue and groove is provided the blocks
interlock and do not need mortar in thevertical joint. This makes laying very easy.
Apply mortar and set the block by moving it
into the groove. Level the block straight
away. This is all.

Cavity
Cavities reduce the weight and increase theinsulation of the blocks. Heat and cold are
less transferred through the wall.
The cavity does not reduce the strength of theblock if the cement mixture is correct.

Columns
The great advantage is the integration of
columns. Special blocks are available with
large cavity that permits to fill them up and
insert reinforcement
Columns are quickly built in this way
without timber and formwork

Disadvantages
Buildings built with cement blocks do not
provide a good living environment like brick
buildings.
Bricks are more natural, temperate and
insulate much better and do not sweat like
concrete blocks that make the climate in the
building rather humid.
