What exactly is Mill Scale and what is done about it

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.

What are the Materials Used for Ferrocement

1. Cement mortar mix. The cement mortar is a mixture of cement, sand, admixtures, and water. Generally, the mix used in the construction of ferrocement has a cement-sand proportion of 1 part of cement to 1.5-2 parts of sand. The mix's water-cement ratio has to be as low as possible to have good workability and quality. 1.1 Cement
