2 Test methodology
The preparation of the concrete specimen (cube with an edge
length of 20 and15 cm) was performed at 7. July 2015, according to
the following concreteformula:
Concrete strength class C 30/37 (0/16 mm, F3)
- Cement CEM ll/A-LL 42,5- Number of varities: 15342100-
Exposure classes: XD1 , XF2
In the center cube samples 1 each spacer was set in
concreted
The storage of the samples was carried out ( in the forms
covered with foil) for24 hours at about 20 ' C. After removal of
the forms a circular area withdiameter fo about 10 cm at the center
area of the testing side with the waterpressure was roughenect.
The storage of specimens for the freeze{haw testing according to
the CDFprocess and testing of the thermal cycling was carried out
according to thestandard.

2.1 Examination water penetration
The test was carried out according to DIN 1048-5, whereby the
specimenswere opplied 5 bar water pressure for 72 hours at the side
of the spacer.Subsequently the test specimens were split in the
direction of sample heightand the depth of water was measured on
the cross section of the cleavedsample.
2.2 Freez-thaw test accordlng to GDF method
The determination ol freeze-ldeicing salt resistance with
di-icing salts solutionwas performed according to DIN CEN / TS
12390-9 with CDF method(alternative method) at the surface of the
concrete cube with spacers.
This test method determines the weathering amount of surfaces
defined by anumber of freeze-thaw cycles in the presence of a
de-icing agent solution. Asa de-icing agent solution a3o/o sodium
chloride solution was used.
Three days before the start of the pre-saturation with the test
solution a lateralseal with aluminum foil with butyl rubber was
applied. There after thespecimens were stored (seven days in the
test solution) for capillary fluidacquisition seven days in the
test solution.
Before starting the freeze / thaw cycles loosely adhering
particles wereremoved from the test surface of the specimens by
treatment in an ultrasonicbath.
It was followed by a stress on the specimen with 28 freeze /
thaw cycles. Theduration of one freeze-thaw cycle tock 12 hours.
The temperature variationcorresponded to the requirements of DIN
CEN / TS 12390-9, Figure 10(temperatures between t 20 " C.)

To determine the surface scaling loose components of the test
areas wasremoved after every 6, 10, 14 and 28lreeze / thaw cycles
by an ultrasonicbath. The weathered material was collected and
filtered. After drying at 105 "C to constant mass, the mass of
scaling was determined and related to theparticular test plots.
2.3 Testing with termal cycling
The test specimen with the cast spacers were subjected to a
ten-time thermalcycling at temperatures between + 60' C and -10'
C.Therefore the dice suúaces were heated by radiant heat for about
I hours at atemperature of + 60 " C. Subsequently the cubes were
stored for about 16hours in a freezer at a temperature of -10 "
C.After ten temperature changes the concrete surfaces were visually
inspectedand photographed.
Test period: 05. August to 28. August 2015
