QAVER

 

The right device for your requirements.

The basis for sustainable, cost-efficient and durable concrete products is excellent product quality. The patented QAVER testing and documentation device offers numerous options for checking the freshly manufactured concrete product and for documenting and improving its properties.

Using the QAVER, properties of the fresh concrete product can be examined immediately after the compaction process. The face and back compaction can be measured independently. The overall raw density is then determined from the height and weight of the fresh product.

The QAVER documents the time of measurement, measurement results, specifications, deviations from the target value and the name of the person responsible for the measurement process. With this documentation, it can be traced which employee has produced which product, in what quality - directly on the device or at any time in the online evaluation tool.

QAVER mobile


 

The portable one

The QAVERmobile is perfect for getting started on the QAVER technology.

Basic equipment:

  • Hand unit with direct display of the compaction result according to the previously defined limit values

The QAVER was developed as a tool for the machine operator to register physical properties of the freshly compacted concrete product. These registered results are compared to previously defined limit values. In this way it is possible to evaluate the product quality, also with regards to reproducible quality. All results and parameters are saved and can later be used for statistical evaluation. Additionally, they can be related to the properties of the hardened concrete product.

The entire measurement process takes a maximum of 30 to 40 seconds and can be carried out easily by anyone after a short instruction.

 

The following values can be measured or determined:

  • compaction of the face concrete in %
  • compaction of the back concrete in %
  • mass in grams
  • height in mm (tolerance +/- 0.2mm)
  • density​ of the stone

 

The QAVER stands for quality control to

  • support the machine operator to comply with specifications
  • indirectly control the moisture of the mix
  • improve product homogeneity ​
  • optimize recipes​
  • monitore set machine parameters​
  • control product homogeneity of an entire warehouse
  • support inexperienced machine operators​​

 

The identified QAVER results are directly related to

  • the porosity of the concrete structure and the connected water absorption
  • the freeze-thaw resistance of the face concrete
  • the firmness
  • the tendency to efflorescence 
  • the functionality of a sprayed up coating

PC-Analysis program

The external evaluation program is a tool to generate and administer products.
This program is installed in the company network or on external computers.

  • device administration 
  • product administration
  • result administration
  • data communication via USB-flash drive or network
  • evaluation of production cycles
  • presentation of the analyses in 3D
  • generation of statistical and graphic evaluations

 

Individual Solutions​

We offer individual solutions for: data exchange, data transfer and data processing.  Please do not hesitate to contact us, and we will work on a solution for your company. 

Server-Client

With the server-client program, many QAVERs at different locations can be integrated into an existing company network. Products and measurement results can thus be managed and processed centrally and independently of location.​

 

Hess-Communication interface ​

Benefits of the communication with the HESS concrete block manufacturing system:​

  • shared user accounts 
  • shared product specifications
  • key figures from the machine
  • quality results of the end product by the QAVER​
  • results of both statistics can be displayed in a combined overview​ ​
