This Standard sets out a qualitative method of detection of sugar in aggregates

This Standard sets out a qualitative method of detection of sugar in aggregates.A positive reaction is given by one part of sugar in one thousand parts of aggregates. No visible reaction is given by one part of sugar in ten thousand parts of aggregates.NOTE: The basis of the test is that, although Fehling's solution does not react directly with cane sugar (sucrose), it does react with glucose (grape sugar). Therefore cane sugar, if present, is first converted into invert sugar (glucose plus fructose) by boiling with hydrochloric acid. The glucose so formed reacts with Fehling's solution, giving a positive test.Although cane sugar is perhaps the most likely sugar source if concrete aggregate is accidentally contaminated, the test also detects contamination from honey, wine, fruit juices or other sources of glucose.
