CSA Group Cementitious materials compendium A3000-18

Preface This is the fifth edition of CSA A3000, Cementitious materials compendium. It supersedes the previous editions published in 2013, 2008, 2003, and 1998. Significant changes from the previous edition include the following: a) Ground glass pozzolans have been introduced as new supplementary cementitious materials. b) Addition of a new Annex A, Evaluation guidelines for the adequacy of alternative sampling and testing frequencies, to A3004-A1, Standard practice for sampling, testing, and inspection, to provide guidance to manufacturers for the evaluation of the adequacy of an alternate testing frequency using accepted statistical practices. c) New requirements have been added for reporting chloride contents of cementitious materials. d) The requirement for total organic carbon testing for limestone has been removed. e) There have been revisions to A3004-E1, Standard practice for the evaluation of alternative supplementary cementitious materials (ASCMs) for use in concrete as SCMs. f) Based on the limited data available at the time of publishing and in an effort to provide an additional measure of protection when portland-limestone cement was to be used in combination with a SCM in sulphate environment, the 2013 edition of CSA A3004-C8 was originally separated into the original test, identified as Procedure A, and a new low temperature test, identified as Procedure B. Subsequent data has found the results of Procedure B not to relate to sulphate resistance in concrete, and that meeting the CSA A3004-C8 Procedure A expansion limits in combination with the requirements in Table 5 was sufficient to show good sulphate resistance in concrete. Therefore, Procedure B was withdrawn in Update 5 of the 2013 edition. g) Other changes have been made to harmonize with various ASTM and ACI publications, including change of terminology from supplementary cementing materials to supplementary cementitious materials.

This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
