Study of magnetically driven concrete ScienceDirect

Study Of Magnetically Driven Concrete Sciencedirect

Sep 15, 2016 In the magnetically driven concrete, the aggregate was replaced by steel slag as the magnetic force carrier. Aggregate, which makes up approximately 70% of the concrete volume, is one of the main constituent materials in concrete. If the aggregate could be driven by magnetic force, whole concrete could be driven by the magnetic force.

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. Beyond that, however, heavy concrete is used to make counter weights and
