As for concrete itself, the density of concrete of normal weight is about 2,400 kg per cubic meter, or 145 lbs. per cubic foot. The concrete density varies depending on the amount and density of the aggregate, how much air is entrapped or purposely entrained, the cement concentration, and the maximum size of aggregate used.What are high-density aggregates?,A. High-density aggregates generally consist of high-density minerals or rocks, or they consist of man-made materials, such as steel or iron. High-density aggregates are used to produce concrete that has higher than normal density, usually for radiation shielding or an application where high-density concrete is needed for counter balancing

With over 330 sites and more than 4100 dedicated employees, we’re home to everything from aggregates, asphalt, ready-mixed concrete and precast concrete products.Aggregates Portland Cement Association,Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete. After harvesting, aggregate is processed: crushed, screened, and washed to obtain proper cleanliness and gradation.

Aggregate Research International.High Density Concrete: Types and Properties Concrete,The grout used in high density pre placed aggregate concrete should be somewhat richer than that used in normal density pre placed concrete. High modulus of elasticity, low thermal expansion, and low elastic and creep deformation are the ideal properties for both high density and normal concrete.
High density concrete is a concrete having a density in the range of 6000 to 6400 kg/cu.m. High density concrete is also known as Heavy weight concrete. High density concrete is mainly used for the purpose of radiation shielding, for counterweights and other uses where high density is required. The high density concrete has a better shieldingDENSITY-RELATED PROPERTIES OF CONCRETE MASONRY ,BASICS OF CONCRETE MASONRY UNIT DENSITY. The density of a concrete masonry unit is expressed as the oven-dry density of concrete in pounds per cubic foot (lb/ft 3 [kg/m 3]) as determined in accordance with ASTM C140, Standard Test Methods for Sampling and Testing Concrete Masonry Units and Related Units (ref. 2).In production, the density of a given concrete masonry unit is
