DIN EN 16908:2017-05 EN 16908:2017 (E) 5 Introduction How to use this docum
26、ent This document provides product category rules (PCR) for Type III environmental declarations (EPDs) according to EN 15804 14 for cement and building lime, in particular to products according to the standards developed in CEN/TC 51 “Cement and building limes”. The European standard EN 15804, “Core
27、 rules for the product category of construction products”, is intended as the core PCR to be followed. This PCR document supplements EN 15804 by giving more detail for specific items relevant to cement and building lime. In all cases where no specific rules are given in this document, EN 15804 shoul
28、d be followed. Therefore, this document should be read in parallel with EN 15804. EN 15804 is normatively referenced in this document and is indispensable for its application. The structure of this document follows that of EN 15804, with all headings and section numbers kept the same. Where a sectio
29、n of EN 15804 applies without modification, this is indicated. Where a section of EN 15804 is not relevant for EPDs covered by this PCR, this is also indicated. The purpose of an EPD is given in the Introduction to EN 15804. Definition of the covered products Cement Cement is defined in standards pu
30、blished by CEN/TC 51 as “a hydraulic binder, i.e. a finely ground inorganic material which, when mixed with water, forms a paste which sets and hardens by means of hydration reactions and processes and which, after hardening, retains its strength and stability even under water”. Building Lime Buildi
31、ng lime is defined in EN 459-1 as a “group of lime products, exclusively consisting of two families: air lime and lime with hydraulic properties, used in applications or materials for construction, building and civil engineering.” Air lime refers to the product which combines and hardens with carbon
32、 dioxide present in air. Air lime refers to the product which combines and hardens with carbon dioxide present in air. Air lime has no hydraulic properties. Air lime is divided into two sub-families, calcium lime (CL) and dolomitic lime (DL). Calcium lime is an air lime consisting mainly of calcium
33、oxide (quicklime) and/or calcium hydroxide (hydrated lime). Dolomitic lime is an air lime consisting mainly of calcium magnesium oxide and/or calcium magnesium hydroxide. Lime with hydraulic properties is a building lime consisting mainly of calcium hydroxide, calcium silicates and calcium aluminate
34、s. It has the property of setting and hardening when mixed with water and/or under water. Reaction with atmospheric carbon dioxide is part of the hardening process. Lime with hydraulic properties is divided into three subfamilies, natural hydraulic lime (NHL), formulated lime (FL) and hydraulic lime
35、 (HL). DIN EN 16908:2017-05 EN 16908:2017 (E) 6 1 Scope The general scope of the core product category rules (PCR) is given in EN 15804:2012+A1:2013, Clause 1. This PCR is primarily intended for the creation of cradle-to-gate EPDs of cement and building lime. In other respects, the scope is as in EN
36、 15804. 2 Normative references As in EN 15804. 3 Terms and definitions For the purposes of this document the terms and definitions of EN 15804 apply. 4 Abbreviations As in EN 15804. 5 General aspects 5.1 Objective of the Core PCR As in EN 15804. 5.2 Types of EPD with respect to life cycle stages cov
37、ered As in EN 15804. Cement and building lime are intermediate products with many different final uses. Cement may for example be used in ready-mix concrete, precast concrete, mortar, screed, base treatment for various types of infrastructures, etc. Building lime may for example be used in plasters,
38、 renders, masonry mortars, calcium silica bricks, autoclave aerated concrete, soil treatment, asphalt mixtures etc. Therefore, it is generally not possible to provide information about the environmental impacts of the products during the construction process, use, and end of life stages, as this wil
39、l greatly depend on how the cement or building lime is used. For this reason, this PCR is primarily intended to support the creation of cradle-to-gate EPDs, i.e. it focuses on the life cycle stages A1 A3: raw material supply, transport, and manufacturing, although other stages may also be included.
40、Information on other life cycle modules may be provided in an EPD if relevant. Particularly information on carbonation of building limes in the life cycle modules A5 and B1 may be provided in EPDs. If additional stages are included, the modularity principle shall be observed (see 6.3.4.1 of EN 15804
41、:2012+A1:2013) in order to produce consistent EPDs. 5.3 Comparability of EPD for construction products As in EN 15804. As cement and building lime are intermediate products, no functional unit can be defined in EPDs for cement and building lime (see 6.3) and therefore no comparisons with other const
42、ruction products can be made based on EPDs according to this PCR. As stated in EN 15804, “EPD that are not in a building context are not tools to compare construction products and construction services”. DIN EN 16908:2017-05 EN 16908:2017 (E) 7 5.4 Additional information As in EN 15804. For addition
43、al information on emissions to indoor air, soil and water during the use stage, please refer to the respective PCR/EPDs for the downstream products such as ready-mix concrete, precast concrete, screed, plasters, masonry mortars, etc. The lime cycle of high calcium lime is shown in Figure 2. 5.5 Owne
44、rship, responsibility and liability for the EPD As in EN 15804. 5.6 Communication formats As in EN 15804. 6 Product Category Rules for LCA 6.1 Product category The product category for this PCR is cement and building lime, particularly those covered by the standards developed in CEN/TC 51. 6.2 Life
45、cycle stages and their information modules to be included 6.2.1 General As in EN 15804. In general, EPDs according to this PCR will be cradle-to-gate EPDs, i.e. will cover modules A1 A3 only. However, downstream processes (including transport, use and reuse, recycling or recovery) may optionally be
46、declared. As an example, information on carbonation of building limes in the life cycle modules A5 and B1 may be provided in EPDs. 6.2.2 A1-A3, Product stage, information modules As in EN 15804. For a more detailed description of the processes in the product stage of cement and building lime see 6.3
47、.4.2. 6.2.3 A4-A5, Construction process stage, information modules As in EN 15804, not relevant for cradle to gate EPDs, but relevant for the information on carbonation of building limes (see 6.3.4.3). 6.2.4 B1-B5, Use stage, information modules related to the building fabric As in EN 15804, not rel
48、evant for cradle to gate EPDs, but relevant for the information on carbonation of building limes (see 6.3.4.3). 6.2.5 B6-B7, Use stage, information modules related to the operation of the building As in EN 15804, not relevant for cradle to gate EPDs. DIN EN 16908:2017-05 EN 16908:2017 (E) 8 6.2.6 C1
49、-C4, End-of-life-stage, information modules As in EN 15804, not relevant for cradle to gate EPDs. 6.2.7 D, Benefits and loads beyond the system boundary, information module As in EN 15804, not relevant for cradle to gate EPDs. 6.3 Calculation rules for the LCA 6.3.1 Functional unit As in EN 15804. As cement and building lime are intermediate products, no functional unit can be defined in EPDs for cement and building lime. A declared unit is used as defined in 6.3.2. 6.3.2 Declared unit As in EN 15804. The declared unit is 1 000 kg of cement or building lime.
