Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Baustoffanalyse hinsichtlich der Ermittlung von Einsatzmöglichkeiten verschiedenster Baustoffe, sowie deren Zustandsermittlung und der Auswahl gegebenenfalls durchzuführender Sanierungsmaßnahmen.The invention relates to a device for analyzing building materials the determination of possible uses of various Building materials, as well as their condition determination and the selection if necessary remedial measures to be carried out.
Dazu ist es nötig, die Porosität und die Wasseraufnahmefähigkeit von porösen Baustoffen zu ermitteln.This requires porosity and water absorption of porous building materials.
Bei fast allen bisher dazu eingesetzten Verfahren ist eine bestimmte Probenform und/oder eine spezielle Prüfeinrichtung, die nur unter Laborbedingungen eingesetzt werden kann, erforderlich. So werden nach DIN 51 058 bzw. TGL 13 724 feuerfeste Erzeugnisse auf Gasdurchlässigkeit in speziellen Einrichtungen geprüft.In almost all of the methods used to date, there is a specific one Sample form and / or a special test facility that can only be used under laboratory conditions. Thus, according to DIN 51 058 or TGL 13 724, refractory products are made tested for gas permeability in special facilities.
Nach DIN 52 617 und TGL 33 433/03 wird die Wasseraufnahme von Putz und Festbeton durch Wasserlagerung und Wägung ermittelt. Eine weitere Methode der Ermittlung der Wassereindringtiefe wird an speziellen Prüfkörpern in Laborprüfständen nach DIN 1048 durchgeführt.According to DIN 52 617 and TGL 33 433/03, the water absorption of plaster and hardened concrete determined by water storage and weighing. A Another method of determining the water penetration depth is on special test specimens carried out in laboratory test benches according to DIN 1048.
Der Erfindung liegt die Aufgabe zu Grunde, die Porosität und damit die Wasseraufnahme von Beton, Natur- und Kunststein und ähnlichem zu ermitteln. Die Messung dieser Kriterien sind ausschlaggebend bei der Auswahl sowie der Zustandsanalyse von Baustoffen. Dabei ist es notwendig, Direkt- wie auch Vergleichsmessungen unter Labor- bzw. Baustellenbedingungen durchzuführen, ohne auf bestimmte Probenformen und/oder spezielle Prüfeinrichtungen zurückgreifen zu müssen.The invention is based on the object, the porosity and thus the water absorption of concrete, natural and artificial stone and the like to determine. The measurement of these criteria is crucial in the selection and condition analysis of building materials. It is necessary to take direct as well as comparative measurements Laboratory or construction site conditions to carry out without certain sample shapes and / or special test facilities to have to.
Diese Aufgabe wird durch die erfindungsgemäße Vorrichtung dadurch gelöst, daß der Porenraum über absolute oder vergleichende Messungen der möglichen Wasseraufnahme des zu prüfenden Materials durch Injektion einer Flüssigkeit ermittelt wird.This object is achieved by the device according to the invention solved that the pore space via absolute or comparative measurements the possible water absorption of the material to be tested is determined by injection of a liquid.
Diese Vorrichtung besteht aus einem vertikal angeordneten Zylinder, in welchem ein Kolben beweglich angeordnet ist. Am oberen Ende des Zylinders ragt eine Kolbenstange so aus dem Zylinder, daß an dieser Kolbenstange unterschiedliche Massestücke zur Belastung des Kolbens angebracht werden können. Die Belastung des Kolbens mit Massestücken geschieht in Abhängigkeit von der Höhe des zu erzeugenden erforderlichen Prüfdruckes.This device consists of a vertically arranged cylinder, in which a piston is movably arranged. At the top At the end of the cylinder, a piston rod protrudes from the cylinder that different weights on this piston rod for loading of the piston can be attached. The burden of Pistons with mass pieces happen depending on the height of the required test pressure to be generated.
Am unteren Ende des Zylinders ist über ein Manometer zum Feststellen und Kontrollieren des Prüfdruckes ein Druckschlauch mit einem Injektor verbunden, mit dem die zu injizierende Flüssigkeit in den zu prüfenden Baustoff eingebracht wird. Zur Messung der injizierten Flüssigkeitsmenge wird der Kolbenweg analog, digital oder mit einem Meßschreiber gemessen. Durch Vergleichsmessungen mit bekannten Baustoffen ist die injizierte Flüssigkeitsmenge ein Maß für die Qualität des Baustoffes, wie Wasseraufnahme, Dichtigkeit, Dichte und Festigkeit.At the lower end of the cylinder is a manometer to lock and checking the test pressure with a pressure hose connected to an injector with which the liquid to be injected is introduced into the building material to be tested. To measure the The amount of liquid injected becomes analog, digital or measured with a recorder. Through comparative measurements with known building materials, the amount of liquid injected is a Measure of the quality of the building material, such as water absorption, tightness, Density and strength.
Nachstehend soll die Erfindung an einem Ausführungsbeispiel näher erläutert werden. The invention will be explained in more detail below using an exemplary embodiment are explained.
In dem vertikalen Zylinder 1 bewegt sich der massebelastete Kolben 2, der einen konstanten Flüssigkeitsdruck erzeugt, welcher durch die den Kolben beaufschlagenden Massestücke bestimmt wird. Dieser Flüssigkeitsdruck wird mit dem Manometer 3 gemessen.Moving in the vertical cylinder 1 is the mass-loaded piston 2 , which generates a constant liquid pressure, which is determined by the masses acting on the piston. This liquid pressure is measured with the manometer 3 .
Über den Druckschlauch 4 und einen Injektor 5 wird die Flüssigkeit in ein Bohrloch 6 in das zu prüfende Material eingepreßt. An dem Maßstab 7 wird der Kolbenweg und damit die eingepreßte Flüssigkeitsmenge in Abhängigkeit von der Zeit abgelesen. Durch Vergleich mit Messungen an anderen Materialien ist es nunmehr möglich, Rückschlüsse auf die Materialeigenschaften und damit in Verbindung stehende Auswahlkriterien zum Materialeinsatz zu treffen.Via the pressure hose 4 and an injector 5 , the liquid is pressed into a borehole 6 in the material to be tested. The piston travel and thus the amount of liquid injected as a function of time are read off on scale 7 . By comparing with measurements on other materials, it is now possible to draw conclusions about the material properties and the associated selection criteria for the material used.
