Introduction
Fresh mortar is brought to a defined level of consistence as measured using the flow table prior to the
assessment of those properties which are used to characterize it.
Consistence is a measure of the fluidity and/or wetness of the fresh mortar and gives a measure of the
deformability of the fresh mortar when subjected to a certain type of stress. The consistence however is not
directly associated with the manner in which the fresh mortar handles when used by a craftsman.
Normally there will be a linear correlation between flow value, measured in accordance with this test
method, and the plunger penetration value measured in accordance with EN1015-4, for the same type of
mortar with increasing water content, but the slope will differ with different types of mortars.
1 Scope
This European Standard specifies a method for determining the consistence of freshly mixed mortars
(inthe following briefly referred to as fresh mortars) including those containing mineral binders and both
normal weight and lightweight aggregates, which is by means of the flow value.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications.
These normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply
to this European Standard only when incorporated in it by amendment or revision. For undated references
the latest edition of the publication referred to applies.
prEN998-1, Specification for mortar for masonry — Part1: Rendering and plastering mortar with
inorganic binding agents.
prEN998-2, Specification for mortar for masonry — Part2: Masonry mortar.
EN1015-2, Methods of test for mortar for masonry — Part2: Sampling of mortars and preparation of test
mortars.
3 Principle
The flow value is measured by the mean diameter of a test sample of the fresh mortar which has been
placed on a defined flow table disc by means of a defined mould, and given a number of vertical impacts by
raising the flow table and allowing it to fall freely through a given height.
4 Apparatus
4.1 A flow table, as described in Annex A, consisting of the following main parts:
— stand;
— rigid table plate and disc;
— horizontal shaft and lifting cam;
— lifting spindle.
4.2 A truncated conical mould, made of stainless steel or brass,60mm±0,5mm in height and with
internal diameter of100mm±0,5mm at the bottom and70mm±0,5mm at the top. The inside surface
and the edges of the mould are smooth. The planes containing the top and bottom edges are at right angles
to its axis. The minimum thickness of the mould wall is2,0mm.
4.3 A tamper, consisting of a rigid, non-absorptive rod of circular cross-section, approximately40mm in
diameter and approximately200mm long. The tamping face is flat and at right angles to the length of the
tamper. The mass of the tamper is0,250kg±0,015kg.
4.4 Calipers, capable of measuring diameters up to300mm with an accuracy of1mm.
4.5 Trowel.
4.6 Palette knife.

5 Sampling, preparation and storage of test samples
The fresh mortar for this test shall have a minimum volume of1,5l and shall be obtained by reduction of
the bulk test sample (see EN1015-2) using a sample divider or by quartering.
Ready to use mortars (factory-made wet mortars which are retarded), and pre-batched air-lime/sand wet
mortars when not gauged with hydraulic binders, shall be tested within their specified workable life.
Mortars that are made from dry constituents and water shall be mixed in accordance with
EN1015-2unless otherwise specified.
The length of the mixing period shall be measured from the moment all the constituents are introduced
into the mixer.
Before testing, the batch shall be gently stirred by hand using a trowel or palette knife in5–10seconds to
counteract any false setting etc., but without any additional mixing of the batch.
Any deviation from the mixing procedure shall be noted.
Two test samples shall be tested.
6 Procedure
Before each test, wipe the disc and the inner surface and edges of the mould (4.2) clean with a damp cloth,
let it dry and lightly lubricate the surfaces with very low viscosity non-resin mineral oil. If the table has
not been used within the last24h, operate it for ten revolutions before use.
Place the mould centrally on the disc of the flow table(4.1) and introduce the mortar in two layers, each
layer being compacted by at least10short strokes of the tamper (4.3) to ensure uniform filling of the mould.
During filling, hold the mould firmly on the disc, using one hand.
Skim off the excess mortar with a palette knife and wipe the free area of disc clean and dry, being especially
careful to remove any water from around the bottom edge of the mould. After approximately15s, slowly
raise the mould vertically and spread out the mortar on the disc by jolting the flow table15times at a
constant frequency of approximately one per second.
Measure the diameter of the mortar in two directions at right angles to one another using calipers (4.4).
State the results in mm to the nearest mm.
7 Calculation and expression of results
Calculate the mean value of the two measurements. This mean value is the flow value for the test sample.
If the individual flow values from the two test samples deviate from their mean value by less than10%,
use this mean value as the flow value of the mortar. If the two individual flow values deviate from their
mean value by more than10%, repeat the test using further mortar from the reduced bulk test sample
(seeClause5) and if the results deviate from the mean value by less than10 % use the mean value from
the repeat test as the flow value of the mortar. If the results differ by more than10 % consider the
measurements unsatisfactory and take fresh test samples from the bulk test sample or laboratory prepared
mortar and repeat the test.

Annex A (normative)
Details of flow table
Details of the flow table defined in this European Standard are shown in Figure 1.
The stand for the flow table shall be made of steel or cast iron. The flow table shall be mounted without
any other support directly on a horizontal, non-sprung and non-plastic, stable base.
NOTE1 A concrete pedestal with a mass of more than25kg is suitable.
The horizontal shaft with the mounted lifting cam when turned at a constant velocity shall raise the
lifting spindle and the flow table by10mm/s±0,2mm/s.
The lifting cam shall be an even steady rising spiral constructed such that it will resume permanent
contact with the lifting spindle from120° after the impact has occurred and through the following240°
rotation up to the next impact.
The vertical lifting spindle shall be fastened at top in the middle of a rigid table plate. Both of these
shall be made of steel or cast iron. The lifting spindle shall be stabilised by bearings spaced
minimum60mm vertical in the stand, the bearings having a tolerance in diameter of0,05mm to0,1mm.
NOTE2 The contact faces of the lower end of the lifting spindle and of the lifting cam should be constructed to ensure long term
performance. A rotatable roller in the lower end of the lifting spindle is suitable. The edge of the lifting cam and the lower end of the
lifting spindle may alternatively be hardened to a Brinell hardness of500kg/mm2.
The rigid table plate shall carry a disc 300mm±1mm in diameter and4mm±0,1mm in thickness
centrally attached to the supporting table plate by means of suitable fixing devices uniformly spaced along
the periphery of the disc. The disc shall be made of a material resistant to corrosion by mortar and with a
smooth surface of maximum0,005mm coarseness, the surface cleaned and lightly lubricated with very low
viscosity non-resin mineral oil prior to testing.
The upper surface of the disc shall have engraved a circle of100mm diameter and0,5mm deep to
facilitate centring of the mould. The disc shall be kept horizontal during the test.
The total mass (M) of the movable parts of the table, i.e. lifting spindle, rigid table and circular disc, shall
be4,2 M 4,5kg.
k k
The flow table shall not be constructed in any way which inhibits its rotation, however the manufacturing
precision of the movable parts of the flow table shall be such that the rotation is restricted to less than
onerevolution per15jolts.
The lifting spindle shall fall without hindrance. It shall be kept clean and lightly coated with very low
viscosity non-resin mineral oil.
At the lowest point, the lifting cam shall clear the end of the lifting spindle such that the boss of the table
plate firmly strikes the counter boss of the table stand. The boss and the counter-boss shall have contact
on the total circular ring, both kept free of any adhering dust or moisture (water, oil etc.).
NOTE3 A45° slope with a width of1mm at the inner diameter of the counter-boss, and an enlargement of the diameter of the upper
bearing of1mm with a depth of3mm is suitable.
