aggregates and the properties of the other components of concrete. Hematite, magnetite, limonite, barite, steel punching and shot, etc are some materials which can be used as aggregates in high density concrete. Heavy weight concrete can be designed in the same way as that of conventional concrete, but the
Oct 13, 2009 This paper discusses properties for heavy-weight self-consolidating concrete (SCC) made with polycarboxilic-based superplasticizer and barite aggregate. Fresh concrete properties were characterized using the suitable test methods employed in SCC. Since segregation is a key issue in this type of concrete due to the large difference between the ...
barite as ne aggregate. Barite is a heavy mineral, having specic gravity in range of 3.5 to 4.5, and is abundantly available in different parts of Pakistan. Radiation shielding of barite concrete was studied experimentally for use in optimization of

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.
