The crushing characteristics of hardened concrete are similar to those of natural rock and are not significantly affected by the grade or quality of the original concrete. Recycled concrete aggregates produced from all but the poorest quality original concrete can be expected to pass the same tests required of conventional aggregates.
· Crushed stone: If you hear the generic "crushed stone" term, it usually refers to stone that has a mixture of stone dust in it. This type of stone is best used for a base when heavy compaction is needed. As a result, it is typically used for the base of concrete and paving projects, foundations of structures, and driveway bases.
Concrete, bricks, tiles and ceramics. ... Paints and varnishes of a type normally used by ers can be classified under the codes indied in brackets if separated out from other waste.
· Classifiion of aggregates based on: Grain Size. The size of fine aggregates is defined as or smaller. That is, aggregates which can be passed through a number 4 sieve, with a mesh size of Fine aggregates include things such as sand, silt and clay. Crushed stone and crushed gravel might also fall under this egory.
Crushed Concrete 6F2 / 6F1. 6F2 A very good general purpose aggregate which ranges in size from 75mm down to dust. This is ideal as an initial layer of hardcore. Especially as a subbase for access roads, buildings, patios and driveways as the course nature of 6F2 make a very good hard wearing surface when compacted.
