Bibliography

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.NOTEA 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.
