This standard 26/30561941 DC BS EN 196-19 Methods of testing cement is classified in these ICS categories:

• 91.100.10 Cement. Gypsum. Lime. Mortar

This document 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 blast furnace slag, or limestone) [1]. This test method can be used in the framework of preventing the risk of alkali silica reaction [2].
