Void ratio is usually used in parallel with soil porosity (n), which is defined as the ratio of the volume of voids to the total volume of the soil The posoity and the void ratio are inter-related as follows: e = n /(1-n) and n = e / (1+e) The value of void ratio depends on the consistence and packing of the soil

Jun 09, 2010· After filling the box level with gravel, start adding water gradually using a graduated jar and stop when the box becomes full and the water starts just overflowing The volume of the water added represents the voids in the gravel and that divided by the volume of the box gives the void ratio
Jan 05, 2009· You could specify the voids and let the contractor select the stone Or you could specify 15" to 3" clean stone, as others have suggestes, but the actual voids will be subject to variation depending on the exact shape of the rock You would have to test the actual stone to be sure BTW, this is a common problem
VOIDS, SETTLEMENT AND WEIGHT OF CRUSHED STONE BY IRA 0 BAKER, PROFESSOR OF CIVIL ENGINEERING INTRODUCTION Crushed stone has become an important material of construc-tion in modern engineering work The chief causes for this are the great increase in the use of plain and reinforced concrete.
ADVERTISEMENTS: After reading this article you will learn about the rock aggregates and its suitability Rocks can be crushed and graded to make aggregate which can be added to a bonding material like cement to form concrete, or bitumen to serve as a road stone Various civil engineering works need different grades of aggregate The [,]
