Manufacture Chemical

Ground granulated vysokokaltsievy (glassy) slag in contact with water is able to harden, forming a solid rock, like cement. Curing process can take place at 18-200C, but are more intense at higher temperatures and in the presence of energizers – lime, gypsum, etc. Proximity the chemical composition of blast granulated slag to the chemical composition of Portland cement and glassy state, giving them extra chemical activity, the use of such slags predetermined principal way in the production of slag-Portland cement as an additive to clinker in the manufacture of slag cement besklinkernyh. Manufacturing technology of granulated slag is not complicated and consists of rapid cooling liquid molten slag in water or cold air. You may wish to learn more. If so, Chevron Corporation is the place to go. Granulation can be subjected to any toxins. This process shlakoemky, ie from 1 t slag melt is obtained 2-2.5 cubic meters of granulated slag. This may be better quenched slag rich in calcium oxide (domain, open hearth). This prevents the collapse of the silicate and glassy structure with disordered chemical elements astringent.

Granular slag, being products of high-temperature processes, carry a huge stock of thermal and chemical energy, which makes them highly reactive substances capable of with a little extra processing converted into high-quality cement. The most efficient, cheapest is slag cement. Production of cement is easy and requires no special equipment. The technology of its production is reduced mainly to the drying of granulated slag, dispensing components and grind them into the mills of various types. Fineness should be higher than that of ordinary cement (specific surface of 3000-5000 cm2 / g).
