POROSITY AND BULK DENSITY OF SEDIMENTARY ROCKS By G. EDWARD MANGER ABSTRACT More than 900 items of porosity and bulk density data for sedimentary rocks have been tabulated. Most of the data are from the more accessible American, British, German, and Swiss literature. The number of porosity determinations per item ranges from 1 to 2,109.

In 2011 the quarry has been able to increase the average blast size to +32 000 T, which is 9 500 T above the previous 10 year average, a 40% increase in the average blast size. In May 2011 the quarry was able to fire the largest blast in the quarry's history of 97,000T. The blast registered only 106 dBL.
Crushed stone or angular rock is a form of construction aggregate, typically produced by mining a suitable rock deposit and breaking the removed rock down to the desired size using crushers. It is distinct from gravel which is produced by natural processes of weathering and erosion, and typically has .
