Problems solved by technology

[0003] However, the difficulty with this method of measurement is that the concrete shrinks or shrinks as it hardens
This means that an air gap is thus created between the sonic probe and the concrete, and this air gap also expands during shrinkage, which results in a large error in the method

Embodiment Construction

[0027] according to figure 1 , the device P according to the invention for the in situ description of quality parameters and / or properties of inorganic binder systems has two walls 1 and 2 which are arranged at a distance a apart. This distance a is determined by the stop sleeves 3 which are pushed onto the bolts 4 in each case. Four screws 4 of this type pass through the walls 1 and 2 in each case, knurled nuts 5 . 1 and 5 .

[0028] Each wall 1 and 2 respectively has a figure 2 The step-shaped recess 6 is shown in dashed lines and can be seen. Viewed from above, the first part of the stepped recess 6 is designed as a flat guide 7.1 or 7.2 for the slide 8.1 or 8.2. With this slide 8.1 or 8.2, the stepped recess 6 can be closed off as a whole.

[0029] A funnel-shaped well 9.1 or 9.2 adjoins the flat guide 7.1 or 7.2, which leads into the oval cavity 10.1 or 10.2. The elliptical cavity 10.1 or 10.2 also opens out through the walls 1 and 2 in this elliptical shape and eve...

Abstract

The invention relates to a device for the in situ characterization of quality parameters and / or the properties of inorganic binder systems, in particular curable mixtures. According to the invention, the binder system should be located in a receiving element (18) with which at least one wall (1, 2) comprising a probe (15.1, 15.2) is associated. A chamber (10.1, 10.2) for a contact material is provided between the binder system and the probe (15.1, 15.2).

Description

technical field [0001] The invention relates to a device for in situ description of quality parameters and / or properties of an inorganic binder system, in particular of a hardenable admixture, corresponding to the generic concept of claim 1 . Background technique [0002] A number of different detection methods for detecting quality parameters and / or properties of inorganic binder systems are known in the prior art. Here, a distinction is made in particular between non-destructive and destructive inspection methods. For example, non-destructive testing methods are known for concrete in which ultrasonic waves are sent through the concrete in order to determine the strength of the concrete. The advantage of this method is that the travel time of the sound waves in the concrete varies according to the hardness of the concrete. [0003] The difficulty with this method of measurement, however, is that the concrete shrinks, or shrinks, as it hardens. This means that an air gap ...
