MODIFIED CHUTE DESIGN FOR SLAG REMOVAL IN …

Additive material . In cement production, the raw material like lime stone (clinker) is used some other additive material are added for cement production such as gypsum, fly ash, slag. The usage of additive material in cement production is to improve the quality of cement, reduce the usage of raw material cost and setting time etc.

Concrete Produced by Steel‐Making Slag (Basic Oxygen ...

A steel-making slag (basic oxygen furnace) obtained from the Kardemir Steelworks was modified to be used as a clinker additive in the cement industry. This study confirmed that the compressive strength values of concretes produced by addition of these steel-making slags up to 30 mass% were within the values of Grade-325 and Grade-425 steel ...

Cement Additive - an overview | ScienceDirect Topics

5.2 Slag utilization as an aggregate in concrete. EAF slag contains a small proportion of amorphous silicon and a high proportion of iron oxide. It has little or no pozzolanic activity compared with blast furnace slag, which makes it unsuitable for use as a cement additive. The great hardness of steel slag has led to it being considered as an ...

Slag Substitution as a Cementing Material in Concrete ...

Cement is replaced by slag from different steel mills, both blast furnace and ladle furnace slag. The percentages of slag substitution by cement are 30%, 40% and 50% by weight. Mechanical, physical and environmental properties have been evaluated. Compressive and flexural strength have been analysed as the main mechanical properties.
