Products and systems for the protection and repair of concrete structures - Test methods - Determination of injectability and splitting test

This European Standard specifies a method for determining the injectability of a product in a capillary network and its adhesion to concrete by measurement of the splitting strength of cylindrical mortar samples resulting from a sand column injection.
NOTE   Whenever the product is of such nature that it may not be premixed and then poured into a container of the size used in this standard, injection can be carried out using a method suitable for the product provided that the pressure can be measured with similar accuracy.

4 1 Scope This document specifies a method for determining the injectability of a product in a capillary network and its adhesion to concrete by measurement of the splitting strength of cylindrical mortar samples resulting from a sand column injection.
2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 196-1, Methods of testing cement - Part 1: Determination of strength. EN 196-3, Methods of testing cement - Part 3: Determination of setting time and soundness. EN ISO 9514, Paints and varnishes - Determination of the pot-life of liquid systems - Preparation and conditioning of samples and guidelines for testing (ISO 9514:1992). ISO 565, Test sieves – Metal wire cloth, perforated metal plate and electroformed sheet – Nominal sizes of openings. 3 Test principle The principle of the test consists on injecting, under a constant pressure, the product in a transparent plastic (polymethylmethacrylate) tube filled with graded sand and kept in a vertical position. The column is injected from its lower end; one measures the time taken by the product to attain the different reference marks drawn along the tube. 4 General requirements for testing 4.1 Apparatus The apparatus used is illustrated in Figure 1. The total length of the rising tube, the joining flexible tube and the connecting branches is (900 ± 5) mm; the inner diameter is (6 ± 0,1) mm. The difference in level between the bottom of the column and the bottom of the injection pot is (400 ± 5) mm in length. The distance between the end of the rising tube and the bottom of the metal container is (20 ± 1) mm. The tube end is cut square. The injection column is fitted with rubber plugs perforated in their centre. The lower plug has passing through it a copper tube, 6 mm internal diameter - 8 mm external diameter, and (50 ± 10) mm in length to which the flexible pipe is fitted. 4.2 Other equipment In addition to the above mentioned device, the following equipment is necessary to carry out the test:  transparent tubes not affected by the products involved (e.g. polymethylmethacrylate) (22,2 ± 0,3) mm in inner diameter and 390 mm in length;  a scale 400 mm long graduated in millimetres; SIST EN 1771:2004
