2020-10-13 tory undertake a study of unit weights of different aggregates that might be furnished for highway usc in Kentucky. Heretofore the Department has considered the unit weight of gravel as 2800 pounds per cubic yard and 2021-1-3 The unit weight of fine and coarse aggregates within the ASTM grading limits are generally in the range of 1450 1750 kg/cu.m. The unit weight values are used in designing concrete mixtures. Voids in between aggregate particles that can be filled by the mortar can also be calculated.

Highway Haterials Research 2016-7-8 DETERMINING UNIT MASS (WEIGHT) OF AGGREGATES TxDOT Designation: Tex-404-A Effective Date: August 1999 1. SCOPE 1.1 3This method describes the determination of the loose mass per m 3(ft. ) of both fine and coarse aggregates. 1.1.1 The unit mass of aggregate in a saturated surface-dry (SSD) condition is intended for use Calculate the unit weight of the aggregate from the following formula: Unit weight per cubic foot = FA Where: Avoid segregation of coarse and fine aggregate by mixing the material thoroughly on a quartering canvas, and by pressing the shovel tip down firmly NWC unit weight: 150 lbs/ft3 (2400 Kg/m3) Aggregates with bulk densities less than 70 lbs/ft3 (1120 Kg/m3) are called Lightweight. Aggregates weighing more 2021-3-20 Normal Weight Aggregate: Produces concrete with unit loads ranging from 23 to 26 kN / m3 with a specific gravity between 2.5 and 2.7. It has crushing strength at 28 days between 15 to 40 MPa. Commonly used aggregates i.e. sand and gravel; crushed rocks such as granite, basalt, quartz, sandstone and limestone. 2021-3-19 The bulk density or unit weight of an aggregate is the mass or weight of the aggregate that required to fill a container of a specified unit volume. Bulk Density = Mass / volume 2021-3-19 Properties and Features of Light Weight Aggregate The lightweight aggregates are natural or synthetic in nature. This will have the weight of 110kg/m3. 2017-6-11 Unit weight of steel 7850 kg/m3, cement 1440 kg/m3, sand (dry) 1540 to 1600 Kg/ m3, brick 1600 Kg/ m3, Aggregates 1750 kg/m3, bitumen 1040 kg/m3
