EN 15743:2010+A1:2015 (E) 5 Introduction The basis for this European Standard has been the national standards already existing in Europe. Supersulfated cement was originally standa
39、rdised in several European countries, Belgium, France, Germany, Netherlands 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 super
40、seded by those based on Portland cement clinker. Standards were either abandoned, 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
41、. It was decided to separate the “common cements“, where the hardening mainly 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 s
42、lag activation by calcium sulfate. A lower heat of hydration than for Portland 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 environment
43、s, such as sulfates. Ongoing developments in material technology as well as 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, C
44、EN Technical Committee TC 51 decided to elaborate a separate standard for 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.

45、+A1:2015 (E)EN 15743:2010+A1:2015 (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 wit
46、h this standard. 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 exch
47、ange of additional 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 T
48、he word “cement“ 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.
