Abstract
Description
Einleitung:Introduction:
Zum Aufbau der Pflasterkonstruktion ist festgehalten worden, dass in der weiteren Beschreibung folgender Zusammenhang beachtet wird:
- 1. Grundaufbau und Rezeptur
- 2. Quasi-Monolith
- 3. Hoch belastbare Bauform für LKW und Bus im Pflaster/Naturstein
- 1. Basic structure and recipe
- 2. Quasi-monolith
- 3. Highly loadable design for trucks and buses in pavement / natural stone
Im einzelnen heißt das, dass aus dem beschriebenen Grundaufbau und vor allem aus der beschriebenen Rezeptur sich eine Bauform ergibt, welche einen Quasi-Monolithen darstellt. Dieser Quasi-Monolith ist vergleichbar aufgrund seiner detailliert abgestimmten Klebeverbindungen mit einem Betonmonolithen. Der Nachweis hierfür kann geführt werden über die vorhandenen Kräfte innerhalb des Betonuntergrundes und der darüber liegenden verklebten Pflasterkonstruktion (Klebekräfte).in the individual means that from the described basic structure and especially from the described recipe results in a design, which is a quasi-monolith represents. This quasi-monolith is comparable due to its detailed coordinated adhesive joints with a concrete monolith. Proof of this can be guided be over the existing forces within the concrete subsoil and the glued paving construction above (Adhesive strength).
Daraus ist im Resultat eine Bauform erreicht worden, die erstmals eine Chance hat, die hohen dynamischen Kräfte, welche durch die Belastung von LKW- und Busrädern in eine Pflaster-/Natursteinoberfläche eingebracht werden, schadlos abzuleiten.from that As a result, a design has been achieved, the first time a Chance has the high dynamic forces caused by the load of truck and bus wheels be placed in a paving / natural stone surface, harmless derive.

Unterlage:Document:
Die Unterlage besteht aus Beton der Güte C 35/40 und enthält eine Unter- und Oberbewehrung.The Base is made of grade C 35/40 concrete and contains one Lower and upper reinforcement.
Haftbrücke: (bezeichnet als INDUCRET-VK-PCC-Haftbrücke)Bonding agent: (referred to as INDUCRET-VK-PCC bonding agent)
Die Haftbrücke ist besonders gekennzeichnet dadurch, dass
- – sie in spachtel- und streichfähiger Konsistenz zu verarbeiten ist,
- – der Bettungskleber darauf frisch in frisch aufgebracht wird.
- It is to be processed in a spatula-spread and spreadable consistency,
- - The bedding glue is freshly applied in fresh.
Die Haftbrücke besteht aus einer speziellen PCC-Zubereitung einer Basis von abgestimmtem Anteilen Zement, Pulverkunststoffen, Verflüssiger und Feinstfüllstoffen unter Zugabe von 6.5–7,5 Liter Wasser.The bonding consists of a special PCC preparation of a base of coordinated Shares of cement, powder plastics, plasticizers and fine fillers with the addition of 6.5-7.5 Litre water.
Die Haftbrücke wird auf die vorbereitete, gereinigte, vorgenässte Unterlage im Spachtel- oder Streichverfahren aufgetragen.The bonding is applied to the prepared, cleaned, pre-soaked pad in the spatula or brushing applied.
Um die notwendige Zwischenlagenhaftung zwischen Unterlage (Beton) und den aufzubringenden BK sicherzustellen, ist je nach Saugfähigkeit der Unterlage und klimatischen Bedingungen die Materialverbrauchsmenge von mind. 1,0 und max. 3,0 kg einzuhalten.Around the necessary intermediate layer adhesion between base (concrete) and to ensure the applied BK, depending on the absorbency the underlay and climatic conditions the material consumption quantity of at least 1.0 and max. 3.0 kg.
Die Haftbrücke ist in Teilabschnitten aufzutragen, damit eine „frisch in frisch" Verlegung des BK zu gewährleisten ist, um einen Haftzugwert von > 1,5 N/mm2 sicherzustellen.

Bettungskleber (BK):Bedding adhesive (BK):
(bezeichnet als INDUCRET-VK-Bettungskleber)(referred to as INDUCRET VK bedding adhesive)
Der Bettungskleber ist gekennzeichnet durch eine bestimmte Verarbeitungskonsistenz (plastisch), Festigkeitsentwicklung (Druckfestigkeiten: ca. 35 N/mm2 nach 24 h und ca. 73 N/mm2 nach 28 d) und Sieblinie der Körnung von 0–4 mm.The bedding adhesive is characterized by a specific processing consistency (plastic), Strength development (compressive strengths: about 35 N / mm 2 after 24 h and about 73 N / mm 2 after 28 d) and grading curve of 0-4 mm.
Der BK besteht aus hochfesten Zement der Güte CEM I–R und Zusätzen wie Microsillica, Verflüssiger und spezieller Zuschlagsieblinie der Körnung 0 bis 4 mm.Of the BK consists of high-strength cement grade CEM I-R and additives such as microsillica, condenser and Special aggregate line of grain size 0 to 4 mm.
Aus der anteiligen Kombinationen resultieren die hohen Festigkeiten. The proportionate combinations result in the high strengths.
Festigkeiten, mit Werten von ca. 35 N/mm2 nach 24 Std. und ca.73 N/mm2 nach 28 Tagen.Strengths, with values of about 35 N / mm 2 after 24 hours and about 73 N / mm 2 after 28 days.
Die Auswahl der Zuschlagsieblinie der Körnung 0 bis 4 mm, mit einem Rezepturanteil von 68 bis 75 % ergibt mit der Wasserzugabe von 6 bis 8% eine erdfeuchte plastische Mörtelkonsistenz.The Selection of the aggregate line of grain size 0 to 4 mm, with one Recipe content of 68 to 75% results with the addition of water of 6 up to 8% a moisture-proof plastic mortar consistency.
Der angemischte BK kann in dieser Konsistenz in Schichtdicken von 20 mm bis 90 mm über Lehren abgezogen eingebaut werden.Of the mixed BK can in this consistency in layer thicknesses of 20 mm to 90 mm above Gauges deducted be installed.
Durch Besprühen mit einer speziellen Zubereitung einer Kunststoffemulsion (bezeichnet mit INDUCRET-VK-Haftbrücke) mit einem Verbrauch von 0,8 bis 1,2 Liter/m2, kurz vor der Verlegung der Pflastersteine, bewirkt diese eine erneute Plastifizierung der BK-Oberfläche, die die stabile Ein- und Anbindung des Pflastersteins sicherstellt.By spraying with a special preparation of a plastic emulsion (called INDUCRET-VK-Haftbruecke) with a consumption of 0.8 to 1.2 liters / m 2 , shortly before the laying of the paving stones, this causes a re-plasticization of the BK surface, which ensures the stable integration and connection of the paving stone.
Pflasterung:Paving:
Es sind Pflastersteine aus Beton und Naturstein zu verwenden. Diese können Abmaße als sogn. Groß,- Klein- oder Mosaikpflaster aufweisen.It Use paving stones made of concrete and natural stone. These can dimensions as sogn. Big,- Have small or mosaic patches.
Das Verlegen der Pflaster erfolgt „hammerfest" in den BK.The Laying the pavement is "hammerfest" in the BK.
Ebenfalls können ferner Granitplatten der unterschiedlichsten Formate verwendet werden.Also can Furthermore granite plates of various formats can be used.
Verfugung: (bezeichnet mit INDUCRET-VK-Fugenkleber)Jointing: (designated with INDUCRET-VK Joint Adhesive)
Der Fugenkleber (FK) besteht aus hochfesten Zement der Güte CEM I–R, Zusätzen wie Microsillica, Pulverkunststoffen, „ Quellmittel„, Verzögerer, Entlüfter und spezieller Zuschlagsieblinie der Körnung 0 bis 1 mm. Aus der anteiligen Kombination, aus hochfestem Zement, dem Anteil Microsillica, dem Anteil Beschleuniger und dem Anteil an Verflüssiger resultiert eine fließfähige Konsistenz mit hoher Früh- und Endfestigkeit mit Werten von ca. 26 N/mm2 nach 24 Std. und ca. 69 N/mm2 nach 28 Tagen.The Joint Adhesive (FK) consists of high-strength CEM I-R cement, additives such as microsillica, powdered plastics, "swelling agent " , retarder, deaerator and special aggregate line of grain size 0 to 1 mm. From the proportionate combination of high-strength cement, the proportion of microsillica, the proportion of accelerator and the proportion of liquefier results in a flowable consistency with high early and final strength with values of about 26 N / mm 2 after 24 hours and about 69 N / mm 2 after 28 days.
Die Kombination aus dem anteiligen Beschleuniger und Verflüssiger bewirkt die gewünschte frühe Erstarrung des FK, so dass die Pflastersteinoberfläche nach einer Liegezeit von 20 bis 35 Min. eine Bürstenreinigung der verfugten Pflastersteinoberfläche zuläßt.The Combination of the proportionate accelerator and condenser causes the desired early solidification of the FK, so that the paving stone surface after a berth of 20 to 35 minutes a brush cleaning the grouted paving stone surface allows.
Der „Quellmittel"-Anteil bewirkt eine dreidimensionale Stabilisierung der Pflasterung in dem BK.The "swelling agent" portion causes a Three-dimensional stabilization of the pavement in the BK.
Diese Bauweise stellt eine Lösung dar, womit Pflaster als Oberflächenbelag als gebundene Konstruktion für hohe Verkehrsbelastungen geeignet ist.These Construction provides a solution which means plaster as a surface covering as a bound construction for high traffic loads is suitable.
