The composition of rubble aggregates must not contain elements that may impair their use in terms of their nature, size, shape and content. Examples include clay lumps, coal, lignite, coke, soluble or insoluble salts, black coal shale, refractory rock, and so on.
Composition of crushed concrete rubble:
1. The percentage of crushed concrete rubble and crushed natural stony material exceeds 90%.
2. The percentage of masonry rubble type material is less than 10%.
3. The percentage of other stony material is less than 5%.
4. The percentage of hydrocarbon mixtures is less than 5%.
5. The percentage of non-stony material is less than 1%.
6. The percentage of organic matter is less than 0.5%.
Composition crushed mixed rubble:
1. The percentage of crushed concrete rubble and crushed natural stony material exceeds 40%.
