24、2010 06:55, Uncontrolled Copy, (c) BSIBS EN 15743:2010EN 15743:2010 (E) 5 Introduction The basis for this European Standard has been the national standards already existing in Europe. Supersulfated cement was originally standardised in several European countries, Belgium, France, Germany, Netherland

25、s and the United Kingdom, and has been used in concrete for foundations and massive structures. The demand for quick setting cements enabling early formwork removal caused the manufacturing of supersulfated cements to be superseded by those based on Portland cement clinker. Standards were either aba

26、ndoned, as in France, or kept in the catalogue of standards but never used, as in the United Kingdom. In discharging the mandate given to CEN, Technical Committee TC 51 considered the large number of different cements involved. It was decided to separate the “common cements“, where the hardening mai

27、nly depends on the hydration of calcium silicates and setting these out in EN 197-1, from “special cements“, i.e. those with additional or special properties. Supersulfated cement hardening depends on granulated blastfurnace slag activation by calcium sulfate. A lower heat of hydration than for Port

28、land cement clinker results in lower early compressive strength than common cements and a significantly lower early heat of hydration. In addition, it produces concrete which has resistance to chemically aggressive environments, such as sulfates. Ongoing developments in material technology as well a

29、s in production technology again open the option to produce supersulfated cement fulfilling the demands and requirements of the market. As the principles in hydration differ from that of “common cements“ covered by EN 197-1, CEN Technical Committee TC 51 decided to elaborate a separate standard for

30、supersulfated cement. The rate of hardening and lower early strength require that additional precautions are considered when using supersulfated cements to ensure adequate concrete curing.

31、2010EN 15743:2010 (E) 6 1 Scope This European Standard defines and gives the specifications of supersulfated cement and its constituents. The definition of supersulfated cement includes the proportions in which the constituents are to be combined to produce products in accordance with this standard.

32、 The definition also includes requirements the constituents have to meet and the mechanical, physical, chemical including heat of hydration requirements. This standard also states the conformity criteria and the related rules. NOTE 1 In addition to the specified requirements, an exchange of addition

33、al information between the cement manufacturer and user may be helpful. The procedures for such an exchange are not within the scope of this standard but should be dealt with in accordance with national standards or regulations or may be agreed between the parties concerned. NOTE 2 The word “cement“

34、 in this standard is used to refer only to supersulfated cement unless otherwise specified. 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 editi

47、 its strength and stability even under water. Supersulfated cements consist mainly of granulated blastfurnace slag and calcium sulfate. They are statistically homogeneous in composition resulting from quality assured production and material handling processes. The link between these production and m

48、aterial handling processes and the conformity of cement to this standard is defined in EN 197-2. In supersulfated cement, in contrast to common cements according to EN 197-1, ground granulated blastfurnace slag is mainly activated by calcium sulfate. In order to accelerate the activation and early h

49、ydration of slag, additional constituents may be added. 5 Constituents 5.1 Main constituents 5.1.1 Granulated blastfurnace slag (S) Granulated blastfurnace slag is made by rapid cooling of a slag melt of suitable composition, as obtained by smelting iron ore in a blastfurnace and consists of at least two-thirds by mass of glassy slag and possesses hydraulic
