Performances of Manganese Slag Cement

Abstract

It is of great importance to innocuity, minimization and reutilization of manganese slag generated in manganese products by electric furnace process. In the paper, ordinary Portland cement is replaced by manganese slag part then to evaluate manganese slag's influence on the mechanical properties. The experimental results obtained show that ordinary Portland cement added less than 20% by manganese slag was improved in mechanical performances and the cement concrete added less than 20% by manganese slag was not changed significantly. To reduce the economic costs, enhance mechanical properties, manganese slag can replace part of cement concrete.
