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.
