  • Magnetite Uses Education Micrex Development Corp

    When used as the aggregate portion of a concrete mix, magnetite increases the density of the concrete to twice that of standard concrete. This so called "heavy concrete" has become a common building material in nuclear plants as well as (in brick form) for the mitigation of radiation in x-ray facilities.Heavyweight concrete,The density achieved will depend on the type of aggregate used. Typically using barites the density will be in the region of 3,500kg/m 3, which is 45% greater than that of normal concrete, while with magnetite the density will be 3,900kg/m 3, or 60% greater than normal concrete.

    Abstract. Magnetite aggregate is used as a absorbing material. In order to study the mechanical properties, absorbing heat and deicing efficiency and frost resistance of magnetite concrete, I prepared the magnetite aggregate concrete with 0, 20%, 40%, 60%, 80% and 100%Effects of Magnetite Aggregate and Steel Powder on Thermal,If normal aggregate and pores are concentrated in the particular area, concrete cannot reflect the effect of magnetite and steel powder. After replacing 30% volume ratio with magnetite, thermal conductivity reasonably meets with the previous numerical techniques and ACI recommendation as shown in Figure 8 .
