Feasibility Study of Using Desulphurization Slag as Binder Material for Concrete Mixing

Abstract:

This study investigated the feasibility of using desulphurization slag as binder material for concrete mixing. Results show that the amount of water required in mortar preparation increased with increasing fineness and proportion of desulphurization slag used. The greater the amount of desulphurization slag, the longer the setting time and the lower the compressive strength are. Moreover, the durability showed a decreasing trend with increase in desulphurization slag used. After 28-day curing, better compressive strength could be achieved with desulphurization slag added. In particular, mortar mixed with almost any proportion of desulphurization slag used, except for 20% and 30%, showed increase in compressive strength exceeding 21 MPa. Durability was also enhanced with desulphurization slag added. In sum, mortar prepared with 5% of cement replaced by desulphurization slag of #200 fineness showed good properties and performance, proving that desulphurization slag can be an ideal binder material for concrete mixing.
