Those so called quarry tiles that aren't 'glazed' (and so are not impervious or as hard) are terra-cotta tiles. As your quarry tiles are thick set them in sand/cement mix; some so called quarries can be quite thin (6 to 8mm) and should be fixed with adhesive ... anyway IMO they aren't quarries when they're that thin, just quarry effect.

EXPERIMENTAL INVESTIGATION. A. Mix proportioning Two grades of concrete M20 and M25 having nominal mix proportion of 1:1.5:3 and 1:1:2 respectively were used by weight and w/c ratio was fixed according to the slump requirement of 60mm. For this concrete mix, quarry dust was added for replacement of sand from 0% to in step of 10%.

Quarrying. Most of the raw materials used are extracted from the earth through mining and quarrying and can be divided into the following groups: lime (calcareous), silica (siliceous), alumina (argillaceous), and iron (ferriferous). Since a form of calcium carbonate, usually limestone, is the predominant raw material, most plants are situated ...
