High density concrete Heavy weight aggregate
When using only MagnaDense as a high density aggregate, concrete with densities up to 4.0 t/m 3 is achievable. Mixing MagnaDense into concrete with other aggregates allows you to produce even heavyweight concrete with densities up to 5.0 t/m 3. With the correct mix design, high-density concrete can still achieve good workability.

Understanding the Density of Concrete • Aggregate
2009-11-26 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.

Advantages of low-density aggregate - concrete.org
There are also low-density, nonstructural concretes having an oven-dry density of 800 kg/m 3 (50 lb/ft 3) or less. These concretes achieve their low density by incorporating low-density aggregates, air entrainment, or preformed foam.

High Density Concrete: Types and Properties
2021-5-11 The density of light weight concrete is about 1900 kg/m 3 and that of normal concrete about 2400 kg/m 3. Thus the density of high density concrete is about 50% more than the density of conventional concrete. However this concrete can be produced of density upto 5200 kg/m 3 using iron as both fine and coarse aggregate.

The Effect of Aggregate Properties on Concrete
2018-5-18 Aggregates form about 75% of concrete by volume. In terms of weight it may form up to 85% of concrete. Therefore attention has to be given on the selection and quality control of aggregates. Although aggregates are inert in nature it has a strong effect on the concrete's thermal and elastic properties. And although it only acts as a filler, it affects the dimensional stability of concrete.
