Rubble - Wikipedia

"Rubble-work" is a name applied to several types of masonry. One kind, where the stones are loosely thrown together in a wall between boards and grouted with mortar almost like concrete, is called in Italian "muraglia di getto" and in French "bocage". In Pakistan, walls made of rubble and concrete, cast in a formwork, are called 'situ', which probably derives from Sanskrit (similar to the ...

Friction angle for loose crushed stone? - Eng-Tips Forums

Jun 26, 2009  keep in mind that loose crushed stone will settle and has pretty substantial voids (so adjacent soil may wash in to it). for the settlement of say #57 stone, i use 1" per 1' of loose #57 stone as an estimate. i'd use caution when trying to assign phi to any poorly compacted materials.

Engineering Properties of Stones and Tests on Stones ...

The more compact grained and heavier a stone the harder it is. Due to alternate wetting and drying the resulting crushing strength can be reduced even up to 30-40%. Being dry stones allow more crushing strength than when wet. It is the ability of a stone to endure and maintain its essential and distinctive characteristics i.e. resistance to decay, strength and
