This document has been prepared by CEN/TC 104/SC8, “Product and syste

17、ms for the protection and repair of concrete structures“, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2002, and conflicting national standar

18、ds shall be withdrawn at the latest by December 2002. This European Standard is one of a series dealing with products and systems for the protection and repair of concrete structures. It describes a method for determining the workability of free-flowing repair concrete mixes. It is one of a series o

22、and, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. 3 EN 1 3395-312002 (E) 1 Scope This European Standard specifies a method for determining the workability of high flow hydraulic cement, PCC and PC based concrete products for the

23、 protection and repair of concrete, as defined in EN 1504-3, whose workability is outside the normal range for concrete as defined in ENV 206. Tests for the workability of repair products and systems based on thixotropic mortar and high flow grout or mortar are contained in prEN 13395-1 and prEN 133

24、95-21 respectively. Normal workability concrete mixes, which can include proprietary formulations, are applied and compacted in accordance with conventional practice. The workability of these products should be assessed using the slump, VeBe or other appropriate method given in EN 206-1. The workabi

25、lity of conventional high flow concrete mixes should be assessed by the method of EN 12350-5. 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

26、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.

Immediately before carrying out the test, flood the surfaces of the funnel and trough with water and drain-off excess water by inverting the test equipment for one minute. Fit the bung and charge the funnel with six litres of concrete. Pull the bung u
