The innovative cored wire based on calcium carbide offers a Si-free alternative to CaSi- CaFe- and pure Ca-wires. Due to its high melting and boiling temperature calcium carbide dissolves in the steel melt creates reducing conditions and feeds calcium to the steel under low turbulence.

The cement industry has for some time been seeking alternative raw material for the Portland cement clinker production. The aim of this research was to investigate the possibility of utilizing iron ore tailings (IOT) to replace clay as aluminasilie raw material for the production of Portland cement clinker. The chemical and mineralogical data of the grey clinker produced are encouraging since values of 51.0 ± 6.9 C3S 22.7 ± 5.3 C2S 8.6 ± 0.4 C3A and 10.8 ± 0.7 C4AF are similar to those

Feb 20 2018 · The effect of high temperature exposure on the durability of fiber-reinforced composite materials based on high alumina cement is studied. A combination of X-ray diffraction- and thermal analyses of hydrated phases shows a simultaneous presence of all principal hydrates (CAH 10 C 2 AH 8 C 3 AH 6 AH 3) in significant amounts during the whole 2–28 days hydration period. Lime had been made for some 5 000 years using clay and then firebrick kilns. Portland cement manufacturing first called for an innovative refractory when rotary kilns were introduced after 1877. The first resistant linings were made of cement-bonded cement clinker. Later on more durable commercial refractories returned to this industry.
