POROSITY TEST: Once the concrete surface area is completely prepped, dry and clean, spray a small amount of water on the concrete surface to observe if the water immediately begins to absorb into the substrate. If beading or puddling occurs, additional surface preparation is required. Repeat the surface preparation process again.


Grinding Process Grinding is a surface finishing operation where very thin layer of material is removed in the form of dust particles. Thickness of material removed is in range of 0.25 to 0.50 mm.

Puddling (metallurgy) - Wikipedia

The process begins by preparing the puddling furnace. This involves bringing the furnace to a low temperature and then fettling it. Fettling is the process of painting the grate and walls around it with iron oxides, typically hematite; this acts as a protective coating keeping the melted metal from burning through the furnace. Sometimes finely pounded cinder was used instead of hematite.

The process of making the various kinds of iron and steel is described below. The difference between iron and steel is based on the amount of carbon contained in the metal. If less than 0.1% carbon is present in the metal, it is termed wrought iron, and it remains a ductile metal that can be heated and welded, but not hardened; it can be ...

The term "refining" is used in a narrower context. Henry Cort's original puddling process only worked when the raw material was white cast iron, rather than the gray pig iron that was the usual raw material for finery forges. For the gray pig iron to be usable, a preliminary refining process was developed to remove the silicon.
