sand and aggregates, crushing, maximum yield

May 23, 2017 Igneous rocks, such as basalt and granite, are an excellent source of aggregate because they are hard, tough, and dense. Sedimentary rocks, such as limestone, are more challenging than igneous rocks to crush. When crushed with conventional compression type crushers they tend to fracture into flat or elongated pieces.

What Is Coarse Aggregate Requirements of Good Coarse

The coarse aggregate with rough texture is preferred because it forms a good bond with the concrete and gives more bonding strength. But the Rough textured aggregate will give less workability . The surface texture of the rounded aggregate with a smooth surface will require less amount of cement paste and hence increased the yield per bag .
