The melting point of mill scale is around 1370 deg C and the boiling point is around 2760 deg C. It has a stable state. It is insoluble in water and alkalis but soluble in most of the strong acids. It is normally classified as non-dangerous waste material. Mill scale particles, flakes, and chips are brittle and have low mechanical strength.
2005. A. Mill scale consists primarily of magnetite, Fe 3 O 4, of characteristic blue-gray "steely" color. An extremely thin outer film of hematite, Fe 2 O 3, is invisible to the naked eye. The inner portion of the magnetite contains fine metal grains and sometimes, residual black FeO (see below), which contribute to the roughness of descaled metal.

2.1 Ferro-cement is a composite material consisting of a matrix made from hydraulic cement mortar and layers of wire or steel mesh reinforcement appropriately dispersed in the matrix with or without addition of steel rod reinforcement. 2.2 Mortar means a mixture of hydraulic cement, sand and water with or without the addition of additives.
The specific gravity of mill scale is in the range of 5.7 to 6.2. Mill scale's melting point is around 1370 deg C and boiling point is around 2760 deg C. It has a stable state and is insoluble in water and alkalis but soluble in most of strong acids. It is normally classified as non dangerous waste material.
Ive said it before on these forums, the biggest problem with Ferro Cement construction is not the materials or method themselves, it is a fine method for boats of sufficient displacement, no, it is the way that it was marketed as a cheap way for joe blow to build a boat and from a material cost this was so but what the promoters neglected to say was that a …
