What Are Crusher Fines and How Do You Use Them in …
When left in their natural states, crusher fines are an alternative to mulch. It can function as a pathway or patio surface when mixed with a stabilizing product, like organic psyllium binders. Similar to sand in texture, crusher fines can give a more flowing, organic appearance to your landscape by softening the appearance of hard lines.

An example provided in the ACI 211 standard states that, "For a fine aggregate having a fineness modulus of 2.8 and a 37.5mm nominal maximum size of coarse aggregate, the table indicates that 0.71m3 of coarse aggregate, on a dry-rodded basis, may be used in each cubic meter of concrete. The required dry mass is, therefore, 0.71 x 1600 = 1,136kg."
