Cement - Performance testing for sulfate resistance - State of the art report

Cement - Performance testing for sulfate resistance - State of the art report

Under the terms of EU Mandate 114, committee CEN/TC 51, cement, building limes and other hydraulic binders, is required to develop standards for ‘common cements’ and also for cements with special properties such as low heat cements, calcium aluminate cements and sulfate resisting cements.
EN 197-1: Composition, specifications and conformity criteria for common cements was adopted in 2000 and was the first harmonised European Standard to be adopted for a construction product.
Since 2000, European Standards for masonry, low heat, low early strength blastfurnace cements, very low heat special cements and calcium aluminate cements have been published.  The development of a prescriptive EN for sulfate resisting cements has been complicated by national differences in the types of cement that are recognised to have sulfate resisting properties.  Note, however, that all nationally standardised sulfate resisting cements meet the requirements of EN 197-1:2000, and that the absence of a specific standard for sulfate resisting cement has not constituted a barrier to trade.

Foreword
This document (CEN/TR 15697:2008) has been prepared by Technical Committee CEN/TC 51 “Cement and
building limes”, the secretariat of which is held by NBN.
This CEN/TR is a state of the art review of the international research literature dealing with testing/assessing
the sulfate resistance performance of cements and related binders. It outlines the difficulties faced by
CEN/TC 51 in applying a prescriptive approach to the specification of sulfate resistant cements and identifies
the different mechanisms and forms of deterioration that occur during sulfate attack. This report compares the
advantages and disadvantages of different test specimen types (paste, mortar or concrete), different exposure
conditions and different techniques used to assess specimen deterioration. The importance of test method
reproducibility is reviewed with reference to the experimental work carried out by CEN/TC 51 during the 1990s.
The report lists the key parameters that must be controlled in any robust standardised method and makes
suggestions for the main features of a pan-European performance test.

Cement - Part 2: Assessment and verification of constancy of performance
SIST EN 197-2:2020

This document specifies the scheme for the assessment and verification of constancy of performance (AVCP) of cements, including certification of constancy of performance.
The document provides technical rules for factory production control, further testing of samples taken at the manufacturing plant (autocontrol testing) and assessment of the performance of the cement, initial inspection of the manufacturing plant and of factory production control, continuing surveillance, assessment and evaluation of factory production control and audit-testing of samples. It also provides rules for actions to be followed in the event of non-conformity and requirements for depots.
In this document, the word "cement" is used to refer both to common cements as defined in EN 197 1 and to other cements and binders for which the relevant product specification standard makes reference to this document and which are submitted for certification. Such a cement is produced at a given factory and belongs to a particular type and a particular strength class, as defined and specified in the relevant product specification standard.
The guidelines given in the Technical Report CEN/TR 14245 [1] contain information for the application of this document.
This document is linked with the Annexes ZA of European Standards covering cements and binders, i.e. EN 197 1, EN 14216, EN 14647, EN 413 1 and EN 15743.
NOTE   The reason for having drafted this separate document is that the provisions it includes are applicable to different products covered by different European Standards.

Guidance
EN 197 2 deals with the assessment and verification of constancy of performance (AVCP) of cements and binders that are submitted for certification. It deals in particular with cases where “further testing” of the product is undertaken, as is the case for attestation system 1+ under the Construction Products Regulation. The products for which EN 197 2 is applicable are: the common cement products and the low heat cements and the sulfate resisting cements, refer to EN 197 1, the very low heat special cements, refer to EN 14216, the supersulfated cements, refer to EN 15743, the calcium aluminate cements, refer to EN 14647, and the masonry cements, refer to EN 413 1.

Method for the determination of C3A in the clinker from cement analysis
SIST-TP CEN/TR 17365:2019

This document describes the analytical procedures used to determine the content of C3A in the clinker starting from a chemical analysis on cement. The method can be applied to CEM type I and IV for the determination of the requirement of C3A, as defined on EN 197 1.
This document describes two methods, traditional wet and XRF analysis (EN 196 2), which can be considered to be equivalent, in the scope of this CEN/TR 17365, for the determination of Al2O3, Fe2O3 and SO3.
The same methods are described in EN 196 2, but for the scope of this document, the X-ray fluorescence (XRF) is the preferred method to be used for the determination of Al2O3, Fe2O3 and SO3.

Methods of testing cement - Part 6: Determination of fineness
SIST EN 196-6:2019

This European Standard describes three methods of determining the fineness of cement.
The sieving method serves only to demonstrate the presence of coarse cement particles. This method is primarily suited to checking and controlling the production process.
The air-jet sieving method measures the retention on sieving and is suitable for particles which substantially pass a 2,0 mm test sieve. It may be used to determine the particle size distribution of agglomerates of very fine particles. This method may be used with test sieves in a range of aperture sizes, e.g. 63 μm and 90 μm.
The air permeability method (Blaine) measures the specific surface area (mass related surface area) by comparison with a reference material sample. The determination of the specific surface area serves primarily to check the consistency of the grinding process of one and the same plant. This method only enables a limited assessment of the properties of the cement in use.
NOTE   The air permeability method may not give significant results for cements containing ultrafine materials.
The methods are applicable to all the cements defined in EN 197.

Methods of testing cement - Part 11: Heat of hydration - Isothermal Conduction Calorimetry method
SIST EN 196-11:2019

This document specifies the apparatus and procedure for determining the heat of hydration of cements and other hydraulic binders at different test ages by isothermal conduction calorimetry.
This test procedure is intended for measuring the heat of hydration of cement up to 7 days in order to obtain correspondence between Isothermal Conduction Calorimetry (ICC) and EN 196 8 and EN 196 9. Nevertheless this test duration may be critical for some apparatus, even if they can work properly at shorter test ages.
Contrary to EN 196 8 this method gives the heat of hydration continuously over the time. Additionally, the heat flow versus time is given.
