High density concrete Heavy weight aggregate LKAB ...

Natural heavyweight aggregate. MagnaDense is a natural aggregate manufactured from the iron oxide Magnetite. Because of its high specific gravity constructors use MagnaDense as a coarse material to produce heavyweight concrete. As a result, you will get high density concrete with more weight, and your project will require less volume.

Coarse Aggregates: Types, Properites Applications

The size of the coarse aggregate depends on the use of the concrete is to be poured. For large-scale concreting operations without complex reinforcement, large aggregates of size 80 mm, 40 mm, 20 mm are used. For the simple construction of residential or other buildings, 20 mm is the maximum size will be used. Aggregates are graded in a concrete mix design and the ratio of each size is ...

Aggregates Difference Between Coarse And Fine How

To shape concrete, aggregate is mixed with cement that is used to lay the base of a road or even a roof in a building.. Many ingredients, such as sand, gravel, stone, crushed rock and sometimes even waste slug from the iron and steel industry, are used to form aggregates.. In general, aggregate is graded as fine and coarse.
