Hangontight....With pieces that large, your density will not be high...likely on the order of 90 to 100 pcf for the crushed concrete. If it were crushed in the manner of a graded aggregate base material, the density would be upwards of 120+ pcf. RAP will be somewhere in the 90 to 95 pcf range, depending on gradation.
Specific Gravity (Gsb) List December 15, 2020 ... Sands, and Crushed Concrete The coarse aggregate for HMA mixes shall follow Article 1004.03 (a) of the Standard Specifications (Adopted January 1, 2012) 6. Aggregate for several PCC uses is required to be tested for Freeze-thaw. Please refer to the "Aggregate Freeze-thaw Rating List" prior to use.
Lightweight aggregate concrete: 2100 kg/m 3. Ordinary concrete: 2300-2450 kg/m 3 Heavy concrete: more than 2500 kg/m 3.

and crushed, using mechanical crushing machines, from rocks. It contains 60% to 75% of total volume of concrete. The weight ... Using specific gravity in concrete mix is important to correlate the voids and the solid bulk of aggregates and to determine the volume of proportions of concrete. II.
Answer (1 of 3): Specific gravity is ratio of mass to volume to that of water. Concrete is made up of using various materials which have different specific gravity. In simple words you can relate the density of the concrete as to specific gravity of it. because the voids present in it are desig...
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.
Specific Gravity is the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. Water, at a temperature of 73.4°F (23°C) has a specific gravity of 1. Specific Gravity is important for several reasons. Some deleterious particles are lighter than the good aggregates.
relating to testing of aggregates for concrete, and it does not include all the necessary provisions of a contract. 1.. SCOPE 1.1 This standard ( Part III ) covers the following tests for aggregates for concrete: a) Determination of specific gravity and water absorption, b) Determination of bulk density and voids,
identification of stone. The specific gravity of aggregates ranges from 2.5 to 3.0.Specific Gravity is the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. Water; at a temperature of 73.4'C (23'C) has specific gravity .Specify gravity is important for several reasons.
The specific gravity of all other materials are compared to water as a fraction heavier or fraction lighter density, no matter how small or large the fraction is. For example, ammonium nitrate has a specific gravity (sg) of 0.73 while dry ammonium sulphate has a …
Tests on the aggregates showed that the recycled concrete aggregates have lower specific gravity and higher absorption capacity than the original crushed granite aggregate. The resistance to ...

Fine Aggregates | Specific Gravity of Sand / Fine Aggregate Fine Aggregates for Concrete Aggregates consist of sand, gravel, and stones, either crushed or and crushed or a suitable combination of them. Aggregate should be strong, hard, dense, durable, and free from injurious amounts of alkali. They should comply with the local Standard Code.
concrete mixtures: curb and gutter, valley gutter, sidewalk, concrete barriers, driveways, temporary pavement, interchange ramps with a commercial average daily traffic (ADT) of less than 250, and concrete shoulders. Do not use crushed concrete coarse aggregate in the following: mainline
