smaller than the old imperial
one. New bricks can
be bonded into old brick word
by slightly increasing the
mortar bed joint.
Comparisons
of metric and imperial bricks

MORTAR and CONCRETE
1
kg. of dry building sand when
mixed with cement and water
will lay approximately one
brick.
2240
Kgs. all-in-ballast will make
approximately 1 cubic metre
concrete.
