Verfahren zur Herstellung eines wasserdichten Baustoffes.
Es sind Baustoffe bekannt, bei denen ein bitumenartiger Grundstoff mit pulverisiertem Mineral versetzt ist, dessen Feinheit etwa durch das 900-Maschensieb bestimmt ist.
Es hat sich nun herausgestellt. dass die Eigenschaften derartiger Baustoffe, wie Widerstandfähigkeit gegen Abnutzung und Wärme, Zähigkeit, Wasserdichtigkeit und Bindekraft dadurch wesentlich verbessert werden, dass man statt dem pulverisierten, also körnigen Mineral, solches in Form von Staub, also in kornfreiem Zustande, verwendet. Es handelt sich dabei um Mineralzusätze, deren Feinheit durch das 4. 900- bis 10.000-Maschensieb gemessen wird.
Durch den absolut kornfreien Mineralstaub wird die kolloidale Wirkung des Bitumens erhöht und voll ausgenutzt.
Gemäss der Erfindung wird zur Herstellung eines derartigen Baustoffes Naturbitumen, d. i. natürlich vorkommendes, oder aus solchem durch Destillation gewonnenes Bitumen, in flüssiger Form mit kornfreiem, beispielsweise bitumen-oder paraffinhaltigem Schieferstaub mit einem Feinheitsgrad, der etwa dem 4. 900- bis 10. 000 Maschensieb entspricht gemischt und das so gebildete Gemisch gegebenenfalls in an sich bekannter Weise mit Füllstoffen versetzt.
Das Bitumen wird durch Erhitzen flüssig gemacht und bei einer Temperatur von etwa 130 - 2000 C mit dem Schieferstaub versetzt. Dieses Gemisch enthält beispielsweise 15-40 0/0 Bitumen und 85 - 60 % Mineralstaub. Bitumen und Schieferstaub lassen sich in ausgezeichneter Weise mischen und es tritt auch bei wiederholter Erwärmung des so erhaltenen Baustoffes keine Entmischung ein.
Der Baustoff kann in Würfel gegossen werden und wird z. B. in dieser Form nach dem Erkalten auf die Baustelle geliefert.
Die Mischung von Bitumen mit Schieferstaub sowie allenfalls mit Füllstoffen wie Sand u. dgl. kann aber auch erst auf der Baustelle stattfinden. Zweckmässig nimmt man auf 12-25 Teile der Schieferstaub-Bitumenmischung 87-75 Teile Füllstoffe. Die Mischung erfolgt bei etwa 170-200 C.
Ein Baustoff der beschriebenen Art kann in der Induslrie vielseitige Vewendung finden, z. B. zum Auskleiden von feuchten Räumen, beim Hoch-und Tiefbau, in Form von Dachplatten für Bausteine, bei Fundamenten u. dgl. Die jeweils erforderliche Festigkeit des Baustoffes wird durch Änderung des Mischungsverhältnisses seiner Bestandteile erhalten.

Process for the production of a waterproof building material.
There are building materials known in which a bitumen-like base material is mixed with pulverized mineral, the fineness of which is determined by the 900 mesh sieve.
It has now turned out. that the properties of such building materials, such as resistance to wear and tear and heat, toughness, water-tightness and cohesiveness, are significantly improved by using such in the form of dust, i.e. in a grain-free state, instead of the powdered, i.e. granular mineral. These are mineral additives, the fineness of which is measured by the 4. 900 to 10,000 mesh sieve.
Due to the absolutely grain-free mineral dust, the colloidal effect of the bitumen is increased and fully utilized.
According to the invention, natural bitumen, d. i. Naturally occurring bitumen or bitumen obtained from such by distillation, mixed in liquid form with grain-free, for example bitumen- or paraffin-containing, slate dust with a degree of fineness that corresponds to approximately 4,900 to 10,000 mesh sieves and the mixture thus formed, if necessary, in itself in a known manner mixed with fillers.
The bitumen is made liquid by heating and mixed with the slate dust at a temperature of around 130 - 2000 C. This mixture contains, for example, 15-40% bitumen and 85-60% mineral dust. Bitumen and slate dust can be mixed in an excellent way and no segregation occurs even if the building material obtained in this way is repeatedly heated.
The building material can be poured into cubes and is z. B. delivered in this form to the construction site after cooling.
The mixture of bitumen with slate dust and possibly with fillers such as sand and the like. But the like can also only take place on the construction site. It is advisable to take 87-75 parts of filler for 12-25 parts of the slate dust-bitumen mixture. Mixing takes place at around 170-200 C.
A building material of the type described can be used in many different ways in industry, e.g. B. for lining damp rooms, in civil engineering, in the form of roof panels for building blocks, foundations u. The required strength of the building material is obtained by changing the mixing ratio of its components.
