EN 12620:2013

• Abstract:

  This European Standard specifies the properties of aggregates and filler aggregates obtained by processing natural, manufactured or recycled materials and mixtures of these aggregates for use in concrete in conformity with EN 206-1 and concrete used in roads and other pavements and for use in precast concrete products. ; It covers aggregates having an oven dried particle density greater than 2,0 Mg/m3 (2000 Kg/m3). It also covers recycled aggregate with particle densities greater than 1,50 Mg/m3 (1 500 kg/m3) with appropriate caveats and recycled fine aggregate with appropriate caveats. ; A list of the source materials that have been considered and indicating those which are within the scope of this standard is given in Annex A (normative).; Requirements are given in EN 16236.; It incorporates a general requirement that aggregates shall not release any dangerous substances in excess of the maximum permitted levels specified in a relevant European Standard for the material or permitted in the national regulations of the member state of destination.; The tables in this standard include categories which are common across the four main aggregate standards: EN 12620, EN 13043, EN 13139 and EN 13242. Not all of these categories are appropriate for aggregates for use in concrete. ; Categories, notes, comments etc, which are grey shaded, should not be used in concrete.; Aggregates used in construction should comply with all the requirements of the relevant European Standards. These standards include comprehensive and specific requirements for natural aggregates, iron and steel making slag and recycled aggregates, dealing with, for example, the stability of certain basalts, the expansion of certain slags and the constitution of recycled aggregates.; For materials from some other secondary sources however, work is ongoing and the requirements are incomplete. In the meantime, such materials, when placed on the market as aggregates, should conform fully to this standard but may also be required to conform to specific relevant additional requirements at the place of use. Additional characteristics and requirements may be specified on a case by case basis depending upon experience of use of the product, and defined in specific contractual documents. ; NOTE Requirements for lightweight aggregates are specified in EN 13055-1.; Requirements for the declaration of the potential of aggregates to release regulated dangerous substances are currently under development. Until such time as these are finalised, attention should be paid to requirements at the place of use.

4.1 General The necessity for testing and declaring all properties specified in this clause shall be limited according to the particular application at end use or origin of the aggregate. When required, the aggregates shall be tested as specified in Clause 4 to determine the relevant geometrical properties. When the value of a property is required but not defined by specified limits the value should be declared as an XXDeclared category, e.g. a value of, say, 55 for the flakiness index corresponds to FI55 (Declared Value). NOTE 1 When a property is not required, a “No requirement” category can be used. SIST EN 12620:2013

Categories, notes, comments etc, which are grey shaded, should not be used in concrete. 4.2 Aggregate sizes All aggregates shall be described in terms of aggregate sizes using the designations d/D, and shall conform to the grading requirements specified in 4.3, except for aggregates added as fillers which shall be specified as filler aggregate. Aggregate sizes shall be described by the pair of sieve sizes in millimetres selected from the basic set, or the basic set plus set 1, or the basic set plus set 2 in Table 1 with d as the lower limit designation and D as the upper limit designation sieve between which most of the particle size distribution lies, (e.g. 0/4mm, 0/2mm, 2/4mm etc.). A combination of sizes from set 1 and set 2 is not permissible. Aggregate sizes shall have D/d not less than 1,4. SIST EN 12620:2013

4.3 Grading 4.3.1 General The grading of the aggregate, when determined in accordance with EN 933-1, shall conform to the requirements of 4.3.2 to 4.3.5 as appropriate to its aggregate size d/D. Aggregates may comprise single sizes, all-in aggregates or combinations of two or more than two sizes. Aggregates supplied as a mixture of different sizes or types should be uniformly blended. When aggregates of significantly different density are blended, caution is necessary to avoid segregation. When assessing aggregates within a system of factory production control, at least 90% of gradings, taken on different batches, within a maximum period of six months, shall fall within the limits specified in Tables 2 to 5 for tolerances on manufacturer declared typical gradings. Size designations and grading categories are essentially categories of convenience and different sizes and grading categories may be used by agreement between supplier and purchaser. Where the specification requires the use of sieves which are a fraction or a multiple of the upper sieve size (eg D/2 or D/1,4 or 1,4D; 2D) the sieve chosen shall be the next nearest from basic set plus set 1 or basic set plus set 2. When a sieve size of the ISO 565 R20 series is closer to the calculated d/2, D/1,4 D/2 size, the manufacturer may choose to use this R20 size; SIST EN 12620:2013
