Floor tiles
Prefabricated tiles made with stabilised
earth can be used for flooring. One advan-
tage is that since they are already dry, shrink-
age only occurs in joints. Miller, Grigutsch
and Schulze (1947, p. 5) recommend the
use of Fe 3 O 4 , oxblood and tar in order to
stabilise these tiles and provide them with
surface hardness. Tests at the Building
Research Laboratory (BRL) showed that a
high degree of surface hardness could be
obtained by adding 6% double-boiled lin-
seed oil in conjunction with compacting the
surface and using floor wax as a polish.
Methods of increasing surface hardness are
described in chapter 14, p. 112.
