WebIn order to reduce stormwater runoff, permeable brick was prepared by compounding with fly ash and steel slag as the main substrate. The study found that the amount of steel slag has a significant influence on the compressive strength of permeable brick. When the proportion of steel slag is 6.5%, the compressive strength of permeable brick after 28 … WebThe permeability of any given steel is dependent on the distribution of ferrite, martensite and austenite in its structure. Permeability values for ferromagnetic steels are usually high, at around 14. This is because the principal metallic phases in these steels at room temperature are ferrite and martensite, both of which have high ...
