1 Introduction

Please read these operating instructions carefully before commissioning, even if you
already have experience with SAUTER measuring instruments.
After receipt of the concrete tester, it should be checked in advance that no transport
damage has occurred, that the outer packaging, the plastic housing, other parts or
even the gauge itself have not been damaged. If any damage is evident, please
notify SAUTER GmbH immediately.

The FC can measure tensile and compressive forces very accurately and it is easy to
operate. In this special version it is suitable to measure the resistance of young
sprayed concrete. It can be held in the hand for measurements. It is although suitable
to cover the procedure according to the EN ISO 14488-2 (Method A) for subsequent
calculation of the compressive strength of concrete.
SAUTER offers optional software and accessories to make the measuring instrument
more versatile in use. Please ask SAUTER or the SAUTER supplier or visit our
website www.sauter.eu.

3 The Shotcrete Tester

SAUTER shotcrete tester supports you to measure accurate readings of the forces
required to penetrate sprayed or poured concrete during the initial strength
development stage of curing. With the force readings you are able to convert the force
values to a compressive strength value. The best use on-site to measure and testing
shotcrete according to BS EN ISO 14488 (Method A).

4

Using

the Tester

4.1 EN ISO 14488-2
This part specifies two methods from which an estimate of the in situ compressive

strength of young hardened sprayed concrete can be made. The strength development
of young sprayed concrete is assessed in the ranges of 0,2 MPa to 1,2 MPa and 3
MPa to 16 MPa respectively with Method A and Method B. The SAUTER Shotcrete
Tester gives you the possibility to test the force values and convert them according to
the EN ISO 14488-2 and gives you an overview of your sprayed concrete quality.

4.2 Principle Method A
This method is used to measure the force required to push a needle of specified

dimensions to penetrate into the sprayed concrete to a depth of 15 mm +/- 2 mm. A
penetrometer indicates the resisting force, through compression of a calibrated spring
from which an estimated compressive strength can be derived from a conversion
curve, to be provided by the producer of the test equipment The tester indicates the
resisting force, from which an estimated compressive strength can be derived by
means of the appropriate example conversion curve, included with the product and
shown in Appendix A.

4.3

Test

protocol

form

The resulting strength calculation from the test data requires the measurement of
compressive force at multiple sample points. A test protocol form (see Appendix 2
Example) is needed to record these data;

 Project – construction site address
 Date
 Test equip Serial No.
 Time
 Place – of the measuring points
 Measurement values

6 FC 1K-BT-BA-e-2020

4.4 Test specimen
No special test specimen is required. The testing procedure can be used for

measurements at any location without advance preparation. A sprayed concrete layer
of no less than 100 mm thickness is required for testing.

4.5 Conversion curves
Appendix A of this user guide contains a graph of conversion curves to enable the

calculation of the equivalent compressive strength (MPa) of the concrete from a tester
force reading (N).

This graph is derived from the example calibration curves provided in EN 14488-2
Annex A (informative) of the test standard.

Two linear curves and their associated formulae are reproduced for two typical
aggregate mixes of <8 mm and <=16 mm respectively. The compressive strength value
on the y-axis may be derived from a resistance force reading on the x-axis either by
direct extraction from the curve, or calculation via the appropriate formula, as indicated.

These curves are provided as reference examples based on data published in the
standard, however the individual concrete rnix will affect the accuracy of the
approximation. The user is at liberty to irnplement their own correlation function if this
would be more appropriate.

5 Test Procedure

 Record time and place of completion of spraying and start of testing.
 Ensure the force indicator is set to zero.
 Apply the device perpendicularly to the surface of the sprayed concrete layer

and steadily push in the needle to a depth of 15 mm in a single continuous
movement. If this is prevented, for instance because of a large aggregate
particle or reinforcement, then discontinue the test and repeat in an adjacent
location.

 Choose the aggregate size 8 or 16 mm.
 Read the resistance force from the scale, record the value on the protocol form

and return indicator to original position.

 Clean the needle if necessary.
 Repeat the test ten times as quickly as possible (and within 1 min for strengths

below 0,5 MPa) in an area representative of the sprayed region.

 Record the time at which the testing is finished (on protocol form).

5.1 Prepare the tester
Check the fit of the measuring tip

If it is worn out, please replace it
Switch on the FC.
Go to Menu choose Measurment an change Unit to “N” if it’s not already there.

Go to Test Menu and switch to Peak.
Go Back to Measurement screen

5.2 Test the concrete at ten sample locations
Prepare the sample data row

To calculate the single representative value for the compressive strength of the
shotcrete at each test instance, 10 individual samples are taken with the tester.

The data are entered into a row on the test protocol form against the timestamp, for
example at 5, 20, 40, 60,120 minutes.

6 Expression of Results

6.1 Calculation of compressive strength
If you use the Excel file (www.kern-sohn.com), it will be calculate the values by itself

and mark the points in the diagram sheet. So you will get a proper clean protocol of
documentation of the quality of your sprayed concrete.

11 Warnings

Incorrectly performed force measurements can lead to serious injury to persons and
damage to objects and must therefore only be performed by trained and experienced
personnel.
In particular, it must be avoided that forces act on the purchased measuring
instrument which exceed the maximum load (Max) of the instrument or which do not
act axially via the external and internal load cell; or if high impulse forces act on the
measuring instrument.

Avoid twisting the loadcell, otherwise it could be damaged and the measuring
accuracy will decrease in any case.

Inappropriate use

Do not use the measuring instrument for medical weighing.
If small quantities of the material to be measured are removed or added, incorrect
measurement results may be displayed due to the "stability compensation" in the
measuring instrument! (Example: Slow flow of liquids out of a container suspended
from the measuring cell).

16 FC 1K-BT-BA-e-2020

Do not apply a continuous load to measuring instruments with external measuring
cell.

Test equipment monitoring

As part of quality assurance, the metrological characteristics of the measuring
instrument and any test weight that may be present must be checked at regular
intervals. The user responsible must define a suitable interval for this purpose as well
as the type and scope of this inspection.
Information on the monitoring of measuring instruments and the necessary test
weights is available on the SAUTER homepage (www.sauter.eu). The weights and
measuring instruments can be checked and adjusted quickly and at favourable prices
in KERN's accredited DAkkS laboratory (traceability to the national standard).
