BS EN 14618:2009EN 14618:2009 (E) 4 1 Scope This document specifies the terminology and classification of the agglomerated stone products. Agglomerated stone products are i
15、ndustrial products mainly made of hydraulic cement, resin or mixture of both, stones and other additions. They are industrially manufactured in geometrical shapes at fixed plants by moulding techniques. They are put on the market in the form of rough blocks, rough slabs, slabs, tiles, dimensional st
16、one works, and any other cut to size products. All other agglomerated stones products not intended to be used for flooring, wall finishes and similar uses (like drainage channels, structural elements, etc.) are excluded from the field of this standard. This European Standard is not applicable to ter
17、razzo tiles covered by EN 13748-1 1 and EN 13748-2 2. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (includi
18、ng any amendments) applies. EN 12670:2001, Natural stone Terminology 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 12670:2001 and the following apply. 3.1 agglomerated stone industrial product manufactured from a mixture of aggregates of various siz
19、es and natures (generally coming from natural stones), sometimes mixed with other compatible materials, additions and binder NOTE The binder could be resin, hydraulic cement or mixture of both (in various percentages). Aggregates consist of natural and/or recycled stones and/or different additions s
20、uch as crushed ceramics, glass, mirrors. They are bound via resin and filler or cement and water or mixture of both. The manufacturing process is irreversible. 3.2 agglomerated stone product semi-finished product manufactured from agglomerated stone in form of blocks or slabs, which can be transform
21、ed in finished slabs, tiles, vanity tops or similar elements. NOTE Under the agglomerated stones term fall architectural elements, complementary to products for flooring and wall finishes, which can or cannot be subsequently cut to size. Products manufactured by the technology of the agglomerated st
22、ones could be impregnated by suitable chemicals in order to waterproof/seal open pores. The products can be also sealed with putty in order to fill in the surface defects accidentally present in some natural stones and other aggregates. 3.3 classification of agglomerated stones classification accord
23、ing to the type of the binder and the nature of the aggregates of the agglomerated stone product NOTE If the volume of the binding material is greater than the volume of the aggregates, the resulting material cannot be classified as agglomerated stone. BS EN 14618:2009EN 14618:2009 (E) 5 3.3.1 class
24、ification according to the type of the binder classification according to the binder of the agglomerated stone product, i.e. resin, hydraulic cement or mixtures of resin and cement NOTE Agglomerated stone product can be bound by resin (e.g. thermosetting resin) or by other suitable organic or inorga
25、nic polymer which can be irreversibly hardened Agglomerated stone product can be bound by hydraulic cement (white or grey). Agglomerated stone product can be bound by mixtures of resin and cement. 3.3.2 classification according to the mineral nature of the aggregates classification according to the
26、mineral nature of the agglomerated stone product, i.e. carbonate nature, silica nature or carbonate and silica nature NOTE Agglomerated stone product can be constituted of aggregates of carbonate nature e.g. marble, limestone, etc. Agglomerated stone product can be constituted of aggregates of silic
27、a nature e.g. quartz, sandstone, granite, etc. Agglomerated stone product either of carbonate or of silica nature can contain aggregates such as crushed ceramics, glass, mirrors, etc. Agglomerated stone product can be constituted of aggregates of both carbonate and silica nature. 4 Terminology of ag
