What is Cement Clinker? Composition, Types & Uses - Civil ...

This concept is used in producing a type of clinker with up to 30% less carbon dioxide emission. Energy efficiency improves and the electricity costs for the manufacturing process are about 15% lower as well. Use of Clinker: Conversion to Cement. Clinker, combined with additives and ground into a fine powder, is used as a binder in cement products.

Properties of Cement- Physical & stone - Civil Engineering

The manufacturing process of Portland cement uses magnesia as a raw material in dry process plants. An excess amount of magnesia may make the cement unsound and expansive, but a little amount of it can add strength to the cement. Production of MgO-based cement also causes less CO2 emission. All cement is limited to a content of 6% MgO. Sulphur trioxide

Manganese - Wikipedia

Manganese compounds have been used as pigments and for the coloring of ceramics and glass. The brown color of ceramic is sometimes the result of manganese compounds. In the glass industry, manganese compounds are used for two effects.

Casting Manganese Steel Liners for Mills or Crushers

Manganese steel is similar in analysis to ordinary first-class converter metal except that it is high in carbon and contains from 11 to 13½ per cent, of manganese. From one standpoint manganese steel is similar to malleable iron in that the casting as it comes out of the sand is hard and brittle and must be made ductile by a heat-treating process.

Manganese: applications and uses-Metalpedia

Manganese sulphate is widely used as an end product in fertilizers and animal feed, and as an intermediate product in the stone industry. An organic manganese compound called MMT (methylcyclo-pentadienyl manganese tricarbonyl) has been used as an octane booster or anti-knock agent in unleaded gasoline.
