Experimental Study on Impact Crushing of Granite Particles
To study the specific influences of production parameters and structural parameters on a vertical shaft impact crusher (VSI), a pneumatic impact crushing device was designed and used to study the influence of different impact velocities, impact angles, and initial particle sizes on the crushing effect for granite particles.

(PDF) A COMPARATIVE ANALYSIS OF CONCRETE STRENGTH USING
The maximum aggregate impact and crushing values are 20% when the aggregate is to be used in heavy-duty concrete floor finishes, 30% for pavement wearing surfaces and 45% for other concrete works [10, 13]. The lower the value of AIV and ACV, the stronger the aggregate i.e. the greater its ability to resist impact and crushing.

Construction material prospects of granitic and associated
Unconfined compressive strength of gneissic and massive Mansehra Granites varies from 61.50 to 66.20 MPa. Owing to lower unconfined compressive strength, higher flakiness and elongation index, aggregate impact and crushing values, the gneissic Mansehra Granite is not recommended as dimension stones, road and cement concrete.

What is the crushing strength of granite?
Explanation: Crushing strength or compressive strength of a stone is the load per unit area at which the stone starts cracking. It should be greater than 100 N/mm 2 to ensure sufficient strength for use in construction. In this way, which Stone has highest crushing strength? The stone whose crushing strength is maximum, is.

Compressive strength test. This test is vital for evaluating the stone’s resistance to crushing loads. A wall stone has to bear the compressive load of the stone’s weight. A stone floor has to withstand loads of people and heavy objects. So, compressive strength is the highest load per unit area borne by the stone without giving in.
