Methods of testing cement - Part 19: Determination of the contribution of cement's alkalis

Abstract

This European standard describes the method for determining the contribution of cement's alkali to the alkali-silica reaction process that can occur in concrete or mortar containing aggregates potentially susceptible to alkali attack. The principle is to consider the alkalis from the insoluble part of the cement (generally associated with fly ash, for example, or pozzolans) and the alkali from the diluted part of the cement (generally associated with clinker, gypsum, granulated blastfurnace slag, or limestone). This test method can be used in the framework of preventing the risk of alkali silica reaction.
