Unter Berücksichtigung des technologisch bedingten Mindestwasseranspruches und der Dichte der Flugasche wird eine Asche-Wasser-Suspension hergestellt, wobei abzusichern ist, daß das Volumen der Suspension in etwa dem Wasservolumen und dem Reindichteverdrängungsvolumen der AscheTaking into account the technologically conditioned minimum water requirement and the density of fly ash, an ash-water suspension is prepared, it being ensured that the volume of the suspension in about the volume of water and Reindichteverdrängungsvolumen the ash
entspricht (W/A-Faktor = 0,4-1,2).corresponds to (W / A factor = 0.4-1.2).
Dies ist bei technologisch bedingtem Mindestwasseranspruch von relativ steifer Suspension nur mit einem Intensivmischverfahren abzusichern. Durch Zugabe von warmem Wasser können die Abbindereaktionen in der Spezialbetonmasse beschleunigt werden, ohne eine vorzeitige Austrocknung (Verbrennung) zu erreichen.This is to be secured with technologically conditioned minimum water requirement of relatively stiff suspension only with an intensive mixing process. By adding warm water, the setting reactions in the special concrete mass can be accelerated without premature drying (combustion).

Zur Ansteifung, Wasserbindung sowie Festigkeit-, Dichtigkeits- und Beständigkeitserhöhung gegen aggressive Medien wird der Asche-Wasser-Suspension ein feinkörniger, mineralischer Stoff, wie bindemitteltechnisch wenig aktive Asche und/oder Zement und/oder sonstige feinkörnige mineralische Rückstände, die kein Zuschlagstoff-Stützgerüst bilden, und/oder andere wasserhaltende Zuschlagstoffe zugemischt, wobei bei einer bindemitteltechnisch wenig aktiven Asche-Wasser-Suspension Zement als Festigkeitsverbesserer und bei einer bindemitteltechnisch aktiven Asche-Wasser-Suspension Zement nur unter Umständen als Aktivator und Festigkeitsverbesserer sowie zur Erhöhung der Dichtheit und Dichtigkeit zugegeben werden muß. Grundsätzlich erhärtet das entstehende Gemisch als schwindfreier, beständiger Beton mit einer hohen Anzahl an Haftbrücken, hoher Biegezugbeanspruchung, gutem Ε-Modul und hoher Dichtheit.For stiffening, water binding and strength, density and resistance increase against aggressive media of the ash-water suspension is a fine-grained, mineral material, such as binder technically less active ash and / or cement and / or other fine-grained mineral residues that no aggregate scaffold form, and / or other water-containing additives mixed with a binder technology little active ash-water suspension cement as strength improvers and in a binder active active ash-water suspension cement added only under circumstances as activator and strength improver and to increase the tightness and tightness must become. Basically, the resulting mixture hardens as shrink-free, resistant concrete with a high number of adhesive bridges, high bending tensile stress, good Ε-Modulus and high tightness.

Zur zielgerichteten technologischen und Gebrauchswertverbesserung wird durch den Mischprozeß und/oder durch Einpreßvorgänge der Frischbeton mit mineralischen und/oder synthetischen Zuschlagstoffen versetzt, wobei sich die Tragfähigkeit und/oder das Elastizitätsverhalten und/oder die Wärmedämmung sowie die technologische Anfälligkeit gegen vorzeitige Austrocknung verbessern.For purposeful technological and utility value improvement is mixed by the mixing process and / or by pressing the fresh concrete with mineral and / or synthetic additives, which improve the carrying capacity and / or the elasticity and / or thermal insulation and the technological susceptibility to premature dehydration.
Nachfolgende Beispiele zeigen unter Berücksichtigung der vorgenannten Grundsätze die Vorteile und vielfältigen Einsatzmöglichkeiten der Spezialbetonmasse auf. The following examples show, taking into account the above-mentioned principles, the advantages and diverse possible uses of the special concrete mass.

Nach Transport, Einbau und Verdichtung mit Vibrationstechnik oder Bitumenfertigern entsteht eine hochwertige fugenlose Verschließschicht. Die Tragfähigkeit und Dichtheit des Überbaus kann durch die Zugabe von 41 Ma.-% gut abgestuften Bitumensplitts beim Mischvorgang noch verbessert werden. Die Aufbringung auf den frischen Unterbau kann dabei in 2-4cm Stärke sofort erfolgen. Bei Zugabe von 2 Ma.-% faserigen, beständigen, rißfesten Rückständen mit kurzer Faserlänge von ca. 5 mm ist eine Verschleißschicht mit etwas geringer Tragfähigkeit, aber höherer Elastizität und Biegezugbeanspruchung herstellbar.After transport, installation and compaction with vibration technology or bitumen finishers, a high-quality jointless sealing layer is created. The load-bearing capacity and tightness of the superstructure can be further improved by adding 41% by volume of well-graded bitumen splits during the mixing process. The application to the fresh substructure can be done immediately in 2-4cm thickness. With the addition of 2% by weight of fibrous, resistant, crack-resistant residues with a short fiber length of approx. 5 mm, a wear layer with a somewhat lower load-bearing capacity but higher elasticity and bending tensile stress can be produced.

Schotter) in die Speziaibetonmasse hineingepreßt wird.c) Road rehabilitation, production as Example 2 b, with an additional coarse aggregate framework (eg gravel) being forced into the special concrete mass.
