Description
Verfahren zum Herstellen von Beton und Mörtel und Vorrichtung zur Durchführung des Verfahrens Die Erfindung betrifft ein Verfahren zum Herstellen von Beton und Mörtel, bei dem das Mischgut im Mischbehälter in Schwingungen versetzt wird.Method of making concrete and mortar and device for Carrying out the method The invention relates to a method for manufacturing of concrete and mortar, in which the mixture in the mixing container is set in vibrations will.
Es sind bereits Verfahren zum Herstellen von Beton und Mörtel bekannt, bei denen das Mischgut beim Mischen zusätzlich in Schwingungen versetzt wird. So ist es auch bekannt, in einem Vormischer Zement, Wasser und Feinstanteile der Zuschlagstoffe mit hoher Frequenz in Vibration zu versetzen, um so die Umhüllung der Feinstanteile der Zuschlagstoffe mit Zementleim zu verbessern. There are already known methods for producing concrete and mortar, in which the material being mixed is also made to vibrate during mixing. So It is also known to use cement, water and fines in the aggregate in a premixer to vibrate at a high frequency in order to encase the fine particles to improve the aggregates with cement paste.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Herstellen von Beton und Mörtel zu schaffen, bei dem ein möglichst niedriger Wasserzementfaktor benötigt wird ohne daß ein Vormischer erforderlich ist. The invention is based on the object of a method for manufacturing of concrete and mortar with the lowest possible water-cement factor is required without the need for a premixer.
Die Lösung dieser Aufgabe wird nach der Erfindung darin gesehen, daß das Mischgut während des gesamten Mischvorganges unter Schwingungen von mindestens 50Hz, vorzugsweise aber 150 dz, bei einer Amplitude von maximal etwa 2 mm gesetzt. The solution to this problem is seen according to the invention in that the material to be mixed vibrates at least during the entire mixing process 50 Hz, but preferably 150 dz, with an amplitude of a maximum of about 2 mm.
Hierdurch wird die Eigenschaft der Thixotropie des Mischgutes ausgenutzt, wobei auch erdfeuchtes Mischgut wesentlich dünnflüssiger wird. Dadurch ist es möglichen, den Mischvorgang intensiver zu gestalten. This makes use of the thixotropy property of the mix, earth-moist mix also becomes much thinner. This makes it possible to make the mixing process more intensive.
Wegen des geringeren Wasserbedarfs und der besseren Zementausnutzung infolge der intensiven Mischung kann die Festigkeit des Betons gesteigert oder aber der Zementanteil bei gleicher Festigkeit vermindert werden. Because of the lower water requirement and better cement utilization as a result of the intensive mixing, the strength of the concrete can be increased or else the cement content can be reduced while maintaining the same strength.
In zweckmäßiger Ausgestaltung der Erfindung soll bei trogförmigen Mischbehältern das Mischgut in horizontale, zykloidenförmige Schwingungen, bei Freifalltrommelmischern dagegen in Schwingungen parallel zur Längsachse des Mischbehälters versetzt werden. In an expedient embodiment of the invention, trough-shaped Mixing containers move the material to be mixed in horizontal, cycloidal oscillations, with free-fall drum mixers however, are set in vibrations parallel to the longitudinal axis of the mixing container.
Zur Durchführung des Verfahrens sind nur geringe konstruktive Ergänzungen an den bekannten Mischvorrichtungen erforderlich, die im wesentlichen darin bestehen, daß der Mischbehälter durch Federn elastisch gelagert ist und durch angebaute Außenvibratoren in Schwingungen versetzt wird. There are only minor constructive additions to carry out the process required on the known mixing devices, which essentially consist of that the mixing container is elastically supported by springs and by attached external vibrators is set in vibration.
Um den Verschleiß der Mischwerkzeuge herabzusetzen, ist es ferner zweckmäßig, daß der Mindestabstand zwischen den Wänden des Mischbehälters und den Mischwerkzeugen größer ist als die Amplitude der Schwingungen des Mischbehälters. It is also used to reduce the wear and tear on the mixing tools expedient that the minimum distance between the walls of the mixing container and the Mixing tools is greater than the amplitude of the vibrations of the mixing container.
In der Zeichnung sind mehrere Ausführungsbeispiele der Vorrichtung zur Durchführung des Verfahrens nach der Erfindung dargestellt. Es zeigt Fig. 1 einen Schnitt durch einen Tellermischer, Fig. 2 Grundriß und Ansicht eines Freifalltrommelmischers, F i g. 3 einen Längsschnitt durch einen Trogmischer und Fig. 4 einen Querschnitt durch den Trogmischer nach Fig. 3. In the drawing are several embodiments of the device for performing the method according to the invention. It shows Fig. 1 a section through a pan mixer, Fig. 2 plan and view of a free-fall drum mixer, F i g. 3 shows a longitudinal section through a trough mixer and FIG. 4 shows a cross section by the trough mixer according to FIG. 3.
Nach F i g. 1 sind im Mischbehälter 1 des Tellermischers Mischvorrichtungen 2 angeordnet, deren Mischwerkzeuge 5 einen Mindestabstand von den Wänden des Mischbehälters 1 einhalten. Am Mischbehälter 1, der elastisch auf Federn 4 gelagert ist, sind Vibratoren 3 angebracht. According to FIG. 1 are mixing devices in the mixing container 1 of the pan mixer 2 arranged, the mixing tools 5 a minimum distance from the walls of the mixing container 1 comply. On the mixing container 1, which is resiliently mounted on springs 4, there are vibrators 3 attached.
Beim Freifalltrommelmischer ist der Mischbehälter 6 innen mit Mitnehmerblechen 7, die zweckmäßig muldenförmig ausgestaltet sind, versehen und in Längsrichtung gegen Federn 8 elastisch abgestützt. In the case of the free-fall drum mixer, the mixing container 6 has drive plates on the inside 7, which are appropriately designed trough-shaped, and provided in the longitudinal direction elastically supported against springs 8.
Durch einen Vibrator 9 wird der Mischbehälter 6 in Schwingungen parallel zu seiner Mittelachse versetzt.By means of a vibrator 9, the mixing container 6 is vibrated in parallel offset to its central axis.
Der trogförmige Mischbehälter 10 nach F i g. 4 ist auf Federn 11 elastisch gelagert und um eine Entleerungsöffnung 12 durch einen hydraulischen Hubzylinder 16 kippbar. Am Mischbehälter 10 sind Vibratoren 13 angebracht, die den Mischbehälter 10 in Schwingungen in einer horizontalen Ebene versetzen. The trough-shaped mixing container 10 according to FIG. 4 is on springs 11 resiliently mounted and around an emptying opening 12 by a hydraulic lifting cylinder 16 tiltable. On the mixing container 10 vibrators 13 are attached to the mixing container 10 set vibrations in a horizontal plane.
Im Mischbehälter 10 können Mischwerkzeuge 15 angeordnet sein, die vom Motor 14 antreibbar sind.In the mixing container 10 mixing tools 15 can be arranged, the can be driven by the motor 14.
