Specifies the procedure for the determination of the influence of watersoluble components from recycled aggregates on the initial setting time of cement.

This European Standard specifies the procedure for the determination of the influence of water-soluble components from recycled aggregates on the initial setting time of cement. NOTE A procedure is described in EN 1744-1:1998, clause 15.3, for use with natural aggregates; this procedure is intended to demonstrate and quantify the effects of organic contaminators. It is not suitable for recycled aggregates because these may also contain inorganic contaminators.
