Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision. For undated references the latest edition of thepublication referred to applies (including amendments).EN 1402-1, Unshaped refractory products - Part 1: Introduction and classification.EN 1402-5:2003, Unshaped refractory products - Part 5: Preparation and treatment of test pieces.3 PrincipleThe amount of water used in a castable mix for preparing test pieces has a significant influence on the test results.Excess water can reduce strength, increase shrinkage, and can cause sedimentation; insufficient moisture can givevoids due to poor compaction, with subsequent lower density and strength.This European Standard describes procedures for determining and measuring the consistency of castables and isapplicable to all types of dense regular castables, dense deflocculated castables and insulating castables todetermine the liquid addition necessary for preparing test pieces according to EN 1402-5.According to the different types of installation and types of castables, this European Standard is subdivided intothree test methods:a) determination of the consistency of insulating castables containing significant amounts of light-weightaggregates such as vermiculite or perlite which would be destroyed by intensive mixing. Such products arenormally installed by rodding;b) determination of the consistency of all types of vibratable castables;c) determination of the consistency of self-flowing castables.To obtain reproducible results, the following factors shall be closely controlled:¾ wet mixing time;¾ batch size, which is chosen for the required number of determinations (e.g. if determination of working time isrequired), and is also related to mixer pan size or bowl;¾ mixer pan size adapted to batch weight to have at least 50 % and a maximum of 75 %, volume loading by thedry batch;¾ temperature (of the water, castable and mix and ambient temperature), of 18 °C to 22 °C for consistency andworking time determination;¾ quantity of water addition used in the test which is rapidly affected when the dry volume loading of the mixerpan drops below 50 % of the total dry capacity, due to the increased metal surface to be wetted;¾ water quality.SIST EN 1402-4:2004
