First they are all concrete, just different application methods. Gunite (dry nozzle)is a dry mix where water is added at the nozzle. Shotcrete (wet nozzle) is premixed wet. They both use high air pressure to force the mixture to stick to the wall. Just as if you take a ball of mud and throw it at something, if wants to stick.
Cementite is iron carbide with the formula Fe 3 C, and an orthorhombic crystal structure. It is a hard, brittle material, essentially a ceramic in its pure form.It forms directly from the melt in the case of white cast iron.ementite contains 6.67% Carbon by weight; thus above that carbon content in the Fe-C phase system, the alloy is no longer steel or cast iron, as all of the available iron is contained in cementite. Cementite mixes with ferrite, the other product of austenite, to form lamellar structures called pearlite and bainite.
