The wastes are investigated as materials for obtaining new concretes with different applications.
A lot of types of wastes resulted as by-products, such as silica fume [1,2,3], fly ash [4,5,6], ground granulated blast furnace [7,8] , slag [9] or resulted from natural rocks (quarry wastes) [10,11] are used in building material industry for obtaining new materials or for improving the characteristics of the existing ones.
Materials The polymer concrete was obtained with epoxy resin type Ropoxid, a Romanian product which in combination with hardener type Romamid was the binder of the aggregates.

Methodology Cobalt (II) salts, such as cobalt (II) chloride hexahydrate, cobalt acetate tetrahydrate, and cobalt (II) nitrate hexahydrate, are mainly used as starting materials.
To mimic the reservoir materials, a sand pack filled with glass beads was used, and an electromagnetic field was applied.
These properties determine how the materials respond to an electromagnetic field (Fig. 8).
