Abstract:
Earthen walls or adobes have been in use over
several thousand years in building houses for mankind.
It has also been empirically known that the buildings
in which these materials are used provide coolness in
summer and warmth in winter. It is because clay is
outstanding in heat insulation and capable of adjusting
the himidity.
However, since the start of modernization in the
buildings with the emergence of the 20th century,
the clay has been pushed aside by cement with hardly
no uses. Such a phenomenon is attributable to the fact
that clay bricks cannot be used in the modern buildings
because they are not substantial enough in the first
place and cause heterogeneous phenomena to take
place when adhered to cement.
