Type A – Crushed stone, higher-quality base. Type B – Crushed or uncrushed gravel, areas with gravel as a local material. Type C – Crushed gravel, +60% with 2 or more crushed faces. Type D - Allows use of Type A or crushed concrete (where economically feasible). Type E – Caliche, iron ore, or for new materials as shown on plans.
mass (m) = volume (V) × density (ρ) For example, let's find the weight of 25 cubic feet of concrete. weight = 25 cu ft × 150 lb/cu ft. weight = 3,750 lbs. Tip: Use our cubic feet calculator to find the volume in feet. For example, let's find the weight of 3.5 cubic yards of concrete. weight = 3.5 cu yd × 4,050 lb/cu yd.

CHAPTER 1—INTRODUCTION. Hydraulic cement concrete is a cement and water paste in which aggregate particles are embedded. Aggregate is granular material such as sand, gravel, crushed stone, blast-furnace slag, and lightweight aggregates that usually occupies approxi-mately 60 to 75% of the volume of concrete.
The mix proportion of the concrete is usually done either by the ACI method (1994) or the BS method (1985). In both methods, the coarse aggregate is the crushed natural stones and the unit weight of this concrete ranges from 140 to 152 pounds per cubic foot (pcf
Formula of Crush Concrete Calculator. The calculation formula utilized by the Crush Concrete Calculator is remarkably straightforward: Volume (Cubic Yards) = ( …
Using Table 7.11, calculate the weight of wet coarse aggregate (non-crushed stone) to make a 6, 400 − lb of air entrained concrete mix with a nominal maximum aggregate size of 0.5 in.

In fact, the dry unit weight of concrete masonry unit has a direct effect on its mechanical properties indicating the importance of unit weight on mechanical performance. Analysis of obtained data presented in Fig. 25 through the current program yields the following expression: (2) f c = 0.018 W - 13.65 where W is the dry unit weight of ...
Normal weight aggregate yields concrete with unit weights ranging from 23 to 26 KN/m3 and a specific gravity ranging from 2.5 to 2.7. These aggregates have crushing strengths ranging from 15 to 40 MPa at 28 days. Sand, gravel, and crushed rocks such as granite, basalt, quartz, sandstone, and limestone are typical aggregate examples.

Recycled CA6. Recycled CA6 utilizes crushed concrete. This crushed rock is a clean, recycled product that is IDOT certified. Select Ozinga Chicago market locations also carry an additional TACO Tier 1 certification. This material is 15% lighter than limestone CA6, which can save you a lot of money on your next project.
Since crushed stone has a unit weight of around 2700 lbs/yd³, and 1 ton is equivalent to around 2205 lbs. we can say that a ton of crushed stone is about 0.82 yd³ in volume. We obtain that value by dividing the weight in pounds by the unit weight in pounds per cubic yard: 2205 lbs / 2700 lbs/ yd³ = 0.8166 yd³ ≈ 0.82 cubic yards.
