void ratio of crushed stone. Void Ratio for Common Gravel Sand Sciencing. Gravel typically has a void ratio about 0.4, regardless of whether it is well or poorly graded, although the void ratio can be affected by the presence of impurities, such as clay or silt. Gravel with clay has a void ratio of about 0.25, while gravel with silt can have a ...

range. Void spaces between the larger rock are filled with the smaller material. Void space is reduced which results in a denser placement of riprap or aggregate that is less likely tosettle or move when under loads. Rock that is poorly graded or gap graded does not have a uniform distribution of sizes within the minimum and maximum range.

Aug 20, 2010 Unit-weight measures the volume that graded aggregate and the voids between them will occupy in concrete. The void content between particles affects the amount of cement paste required for the mix. Angular aggregate increase the void content. Larger sizes of well-graded aggregate and improved grading decrease the void content.

Sep 26, 2013 Swell Factors for Various Soils. A cubic yard of earth measured in its natural position swells to more than a cubic yard after it is excavated. This occurs because of an increase in voids. Swell is expressed as a percentage of natural volume, for example, if 10 yd 3 in the ground becomes 13 yd 3 after excavation, the swell factor is 30.

Porosity, itself, is a rather easy parameter to defi nethe fraction of void volume over total volume - but certainly not so easy to quantify.

Mar 18, 2019 It also doesnt matter much what size they are, at least until you get down to sand size. Sand runs about 30 void. So does big rock. But a mix of sand and big rock will end up with sand filling 70 of the voids in the big rock. so you get 30 of 30 void 9. You will lose some volume over the years from debris infiltrating 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. I think the void ratio would also vary by what size of riprap is being placed.
