Metallurgical Slag-based Concrete Materials Produced by Vortex Electromagnetic Activation

摘要

The article presents the results of utilization of blast furnace slags as a source for preparation of clinker-free cement materials for road and civil construction. Simple and high-yield approach for mechanical activation of metallurgical slag with cheap chemical modifiers using Vortex Electromagnetic Activation technique was demonstrated to produce cement with high mechanical properties. Such approach may be used for effective and low-energy utilization of industrial scale-produced slags in concrete materials. This paper describes simple high-yield approach to produce clinker-free cement materials based on blast furnace slag using new type of Vortex Electromagnetic Activation apparatus and cheap chemical modifiers, such as fly ash and sodium hydroxide. Using of such approach allowed us to produce clinker-free cement materials with compressive strength almost 2 times higher as compared with pure Portland Cement materials.
