This is the mass of aggregate that would fill a container of 1m3 capacity.
The density of crushed concrete varies depending on the gradation and quantity of impurities (e.g. asphalt and other) but can be estimated at 1900-1950 kg/m^3.
Wet Concrete:In Wet concrete the property of the concrete is suggested based on the individual material contribution .Hardened Concrete:In Hardened concrete the property of the concrete is identified as a whole.
For normal concretes it should be 2400kg/m^3 but for lightweight concretes it should be 1750kg/m^3.

Bulk density is the dry mass of the solids (M sub t) / total volume (V sub t) Particle density is bulk density (P sub b) / 1 minus total porosity (1-theta).
Dry concrete has a greater density than wet concrete because the water content in wet concrete decreases its overall density. When the water in wet concrete evaporates during the curing process, the concrete becomes denser.
To calculate dry density from the weight of wet sediment, you need to first determine the volume of the wet sediment. You can do this by dividing the weight of the wet sediment by the bulk density of the sediment. Once you have the volume of the wet sediment, you can then calculate the dry density by dividing the weight of the wet sediment by the volume of the wet sediment.

Daft question really! Should be what is the density of cement. Does the question mean cement ( dry powder), wet concrete, set concrete or what?
It will depend on (a) the bulk density of the dry sand and (b) the moisture content of the wet sand.
Concerning the second Question: "Can you find bulk density with just this info?"Purely on mathematical insight and analysis:Yes, you should be able to find the bulk density of dry soil, given the 'dry overall' and the 'particle' densities.When wet, there is not enough 'given'Also some should be known about the (or your) definition of porosity
Bulk density = dry weight / volume, then by knowing the dry weight and bulk density we can calculate the volume.
bulk density depend on that material from which soil formed. so maximum bulk density depend on particle density of that mineral. Therefore,we can only tapped the soil upto perticle density. so maximum bulk density may be occur at equal to paricle density.
The bulk density of magnetite can be calculated using the formula: Bulk Density = (mass of material) / (volume of material). This formula involves measuring the mass of the magnetite sample and calculating its volume to determine the bulk density.

unit weight= weight/volume.unit weight of normal concrete = 24 MPaIt is also known as density of concrete
