BS EN 13395-2:2002 – Products and systems for the protection and repair of concrete structures — Test methods — Determination of workability — Part 2: Test for flow of grout or mortar
1 Scope
This European Standard specifies a method for determining the workability (or consistence) of flowing-grade hydraulic cement mortars CC, polymer modified hydraulic cement mortars PCC and polymer bound mortars PC for the protection and repair of concrete, as defined in EN 1 504-1 .
The method is suitable for high flow grouts or mortars that have a maximum aggregate size of 4 mm.
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 (including amendments).

3 Terms and definitions
For the purposes of this European Standard, the terms and definitions contained in EN 1 504-1 and the following apply.
3.1
flow value
distance that the grout or mortar has travelled along a trough after 30 s
4 Principle
The principle of this test is to provide a relevant method to evaluate the workability of flowing repair grouts or mortars in the laboratory, which reflects the actual workability requirements for site repair works. The test measures the flow of a fixed quantity of the grout or mortar along a defined trough after 30 s. The distance that the grout or mortar has travelled in that time is the flow value.
NOTE The method of test is sufficiently robust as to be suitable for use as a quality control technique in on-site laboratories.
5 Equipment
5.1 Mixer : Unless stated otherwise by the manufacturer, the equipment to be used for mixing the constituents for the grout shall be the standard type of mixer specified for producing cement mortars in EN 1 96-1 .
5.2 Grout flow trough : A grout flow trough fabricated in accordance with Figure 1 .
5.3 Measuring jug : Capable of taking the required one litre of grout used in the grout flow trough.
5.4 Standard laboratory climate of (21 ± 2) LC and (60 ± 1 0) % RH.
