Low Alkali Portland Cement Clinker
Low Alkali Portland Cement Clinker (Grey)
| Product Name | Low Alkaline Portland Cement Clinker (Grey) |
| Sales Method | Bulk |
| Description | Raw material mixtures prepared from limestone and clay-derived materials and other auxiliary materials (iron ore, bauxite, etc.) with the highest quality and in a stable homogeneous manner; It is a clinker product obtained by heating at high temperature and sintering at a temperature above 1400 0C.
It has a lower equivalent alkaline ratio than Portland Cement clinkers and is resistant to alkali-silica reactions. The equivalent alkaline value in clinker is maximum 0,60%. |
