9 Test methods
9.1 Determination of flexural and compressive strength
9.1.1 Apparatus
9.1.1.1 Three gang mould shall consist of three horizontal compartments so that three prismatic
specimens 40 mm x 40 mm x 160 mm can be prepared simultaneously (see EN 196-1:2016, 4.5).
9.1.1.2 Jolting apparatus or jolting table used for the compaction of 40 mm x 40 mm x 160 mm grout
specimen, which shall comply with EN 196-1:2016, 4.6.
9.1.1.3 Flexural strength testing machine shall be capable of applying the load with suitable capacity and
sensitivity for the test. The machine shall be provided with a flexure device in accordance with
EN 196-1:2016, 4.7 (see Figure 1).
9.1.1.4 Compressive strength testing machine shall comply with EN 196-1:2016, 4.8. The test requires
the use of a jig (in accordance with EN 196-1:2016, 4.9) to be incorporated in the lower platen; the upper
platen receives the load from the machine through an intermediate spherical seating (see Figure 2).
9.1.2 Preparation of test specimens
Mould the specimens immediately after the preparation of the grout, with the mould firmly clamped to
the jolting table.
Introduce, using a suitable scoop, the first of two layers of grout into each of the compartments, directly
from the mixing bowl. Spread the layer uniformly, then compact using 60 jolts.
Introduce the second layer of grout, level and compact with a further 60 jolts.
Lift the mould gently from the jolting table, strike off excess of material and smooth the surface with a flat
trowel. Wipe off the grout left on the perimeter of the mould.
Cover the mould with a glass plate according to EN 196-1.
Place the mould, suitably identified, on a horizontal base in standard conditions, (23 ± 2) °C and
(50 ± 5) % R.H.
After 24 h carefully remove the specimen from the mould.
Keep the demoulded prism in standard conditions for 27 d, leaving a clearance of at least 25 mm on all
sides.
Prepare three specimens for each grout.
9.1.3 Flexural strength under standard conditions
After conditioning has been completed, place the prism in the testing machine (9.1.1.3) with one side face
on the supporting rollers and with the longitudinal axis normal to the support.
Apply the load vertically in accordance with the procedure described in EN 196-1:2016, 9.1.
Keep the prism halves in standard conditions until tested in compression.
9.1.4 Compressive strength under standard conditions
Test the prism halves broken in flexion, by means of the equipment specified in 9.1.1.4 and following the
procedure described in EN 196-1:2016, 9.2.
9.1.5 Flexural and compressive strength after freeze-thaw cycles
Prepare the test units in accordance with 9.1.2.
Condition the test units for 6 d in standard conditions and then immerse in water for 21 d before carrying
out 25 freeze-
