<p>The object of the invention is to use a finely divided calcium hydrosilicate material, in particular aerated or foamed concrete, as a substance for binding and clearing of urine and excrements of the kind excreted for instance by our pet animals. This material gives rapid and effective drying of the excrements, which, particularly if the material is combined with gypsum as a bond-improving agent, become extremely easy to remove or clear.</p> |
