Nov 01, 2005· 1) Determine riprap density from source...assume 155 lbs/ft3 in this case. That's about 2.09 tons/cy of 'rock' 2) Now the part I need someones experience on is how much void to factor in. If voids account for 33% of the total volume then this reduces to 1.5 tons per 'neat' cy. I realize this can vary, but what we have to use something.
CHAPTER 13. BLASTING ROCK ENCE 420 ©Assakkaf Slide No. 39 BURDEN The actual diameter will depend on the manufacturer’s packaging container thickness If the specific product is known, the exact information should be used Rock density is an indicator of strength, which in turn governs the amount of energy required to cause breakage
King County commonly uses two classes of riprap: light loose and heavy loose riprap. The classes, taken from the Washington State Department of Transportation’s (WSDOT) specifications, delineate the size range and gradation for each class. In practice, the actual size of rock obtained varies with the quarry from which it is acquired.

Jan 15, 2019· For example, the density of a one-inch cube of iron is much greater than the density of a one-inch cube of cotton. In most cases, denser objects are also heavier. The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water.
Gravel, loose dry weighs 1.522 gram per cubic centimeter or 1 522 kilogram per cubic meter, i.e. density of gravel, loose dry is equal to 1 522 kg/m³.

Solid rock is estimated at 2.5 to 3tons per cubic meter. If rock is crushed into uniform sizes, the presence of open space between the particles causes the load to be lighter -- approximately 1.6 tons per cubic meter. Mixed sizes of crushed rock can range from 1.6 to 2.2 tons per cubic meter.
Stone, crushed weighs 1.602 gram per cubic centimeter or 1 602 kilogram per cubic meter, i.e. density of stone, crushed is equal to 1 602 kg/m³. In Imperial or US customary measurement system, the density is equal to 100 pound per cubic foot [lb/ft³], or 0.926 ounce per cubic inch [oz/inch³] .
A stone quarry typically produces the following products: Large size blocks blasted from the quarry face, from approximately 0.5 m 3 (approximately 0.36 tonne weight) to 1.25 m 3 (approximately 5-6 tonne weight), are called rip rap or rock armour and are used in coastal and river flood defence schemes to shore up sea fronts and river banks.

Drilling is done with heavy duty down-the-hole hammer drill to a preset blasting pattern. The blasting parameters are designed to suit the rock conditions and gradation requirements.
As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/cu.ft (pounds per cubic foot) and if we know that ammonium nitrate has a sg of 0.73 then we can calculate that its density is 0.73 x 62.4 = 45.552 lbs/cu.ft. Note, kg/cu.m divided by 16.02 = lbs/cu.ft
