Crushed stone: The term "crushed stone" 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.
In concrete compression test, normally 150mm x150mm x150mm ... Why isn't 100mm x100mm x100mm concrete cube samples used in the test ... the stress under a 150mmx150mmx150mm cube is not sufficient to crush the concrete cube.

Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are application drawbacks that may make another crushing solution more appealing. First, cone crushers cannot accept all material sizes. Any material fed to the crusher must be pre-sized for that particular crusher (usually 200mm or less).

It is realized by concrete engineers and research workers that the crushing strength of concrete, deter mined from the crushing strength of a cube or cylinder, is affected by factors which are not intrinsic to con crete and whose influence is not so obvious and direct. Important among these are the shape and size of test
crusher stone dust is one of the materials to replace river sand as an alternative for fine aggregate. By utilizing the crusher stone dust it will be serves as ecofriendly materials as well as economical in making concrete. The forms of crusher stone dust by disintegration are enormously used in production of mortar & concrete. 2.
Test Procedure Of Compressive Strength Of Concrete Cubes: There are two types of specimens either cubes of 10 cm*10 cm*10 cm or 15 cm*15 cm*15 cm both depend on the sizes of aggregates used.
