Aug 20, 2015· * The bulk density is the mass of the material related to a specific volume and for cement is normally expressed as “kilograms per cubic metre” * The bulk density reflects the volume taken up by the cement plus any air trapped between the p.

On Aggregate Grading , rodded unit weight and supplied that information to us We provided the protocol for these tests by suggesting proportions for combined aggregates that were typical , Coarseness factor is the weight of the material retained above the 3/8 in (95 mm) sieve divided by the weight of the material .

May 05, 2011· The contractor took a sample and came up with a dry rodded unit weight The inspector used the Nuclear Density gauge (on back scatter) to come up with a density reading The spec calls for the stone to be compacted to of the rodded value I don't believe that you can compare a back scattered compaction value with the rodded density

Jul 30, 2012· After that, weight the aggregate mass that is inside the container and divide it by the volume of container This will give you the bulk density of the loose aggregat Compacted Bulk Density Compacted bulk density can be determined by filling the container in three layers and tamped each layer with a 16mm diameter rounded nosed rod

The weight of gravel per cubic yard is approximately 2,970 pounds, or 148 tons, if the gravel is dry If the gravel is out of water, the weight per cubic yard is approximately 1,620 pounds or 81 tons Comparatively, other building materials are much heavier or much lighter

Jun 09, 2005· For example, the weight of poured in place concrete, with reinforcement, is only 150 lb/ft^3 There is no way that compacted base weighs more than that You're going way off on a tangent using some inappropriate information and extrapolating it to fit , JedClampett - sorry, but we have compacted crushed stone coming in at over 150pcf Why .

quality requirements of crushed stone It shall be reasonably uniform in density and shall have a dry-rodded weight of at least 112 kilograms perone tenth cubic meter (seventy pounds per cubic foot) 3 Gravel and chert shall be screened and all oversize material may be ,

Determine the net weight of water in the measure to an accuracy of ± 01 % 3 Measure the temperature of the water and determine its unit weight from Table 2, interpolating if necessary 4 Calculate the Factor, F, for the measure by dividing the unit weight of the water

Jun 09, 2005· You need to talk to someone with experience in doing this calculation For example, the weight of poured in place concrete, with reinforcement, is only 150 lb/ft^3 There is no way that compacted base weighs more than that You're going way off on a tangent using some inappropriate information and extrapolating it to fit

SATURATED SURFACE-DRY SPECIFIC GRAVITY AND ABSORPTION OF AGGREGATES TxDOT Designation: Tex-403-A Effective Date: August 1999 , 23 Saturated surface-dry specific gravity—the ratio of the mass of SSD aggregate , 3 REPORT FORMS 31 Moisture Properties and Unit Weight of Concrete Aggregates 4 APPARATUS 41 Glass jar, 2 L (05 gal), and .

Based on their findings, Brown and Mallick suggest using the dry-rodded unit weight apparatus (AASHTO T 19) to determine when coarse aggregate stone-on-stone contact exists in an SMA mixture To use this approach, the coarse aggregate only fraction of the SMA mixture is placed in the unit weight bucket and its density determined

volume of the container to yield the dry rodded unit weight in terms of weight per volume such as pounds per cubic foot By knowing the dry rodded unit weight of a nominal maximum size coarse aggregate and the fineness modulus of the fine aggregate, the weight of the coarse aggregate needed per unit volume of concrete mix can be estimated

Apr 24, 2017· The volume of voids is made up of tiny gaps between particles of the material Calculating the volume of voids can be complex, requiring high-tech tools such as measuring lasers , For example, if the weight of sand plus water was 450 g more than of the water alone and the volume increase was 180 ml, you have a specific gravity of 450/180 = 2 .

Rip rap weighs between 15 and 20 tons per cubic yard Rip rap varies in weight because smaller sizes of rip rap can pack more stone into each cubic yard Rip rap is crushed stone that has been separated by size; it comes in various size categori Each size category is defined by the diameter of the stones, such as 4 inches or 9 inch
