Dolomite has a slightly lower trigonal symmetry than calcite. The chemical composition of natural dolomite is close to the CaMg(CO 3) 2 end-member, but it can incorporate some Fe 2+, since a continuous solid solution with ankerite [CaFe(CO 3) 2] exists. Other elements that may enter the structure of dolomite are Mn, Zn, and Pb.

Basalt fibre is a type of continuous fibre prepared from natural volcanic rock and ore after melting at high temperature. The raw material for basalt fibre (andesitic basalt, andesite basalt, diabase and other volcanic rock) belongs to the family of inorganic nonmetallic silicates and is characterized by high Fe 2 O 3 or FeO content. The high Fe …

The main problem standing in the way of wider use is the very different quality (composition) of the basalt from which the fibers are obtained. Thus, it is almost impossible to produce a consistent quality of fibers, because even basalts of the same deposit can have different compositions. On the other hand, their colour is similar to that …

The basalt fibers are unwind of as many bobbins roving as necessary to get the desired diameter of the rebar. During the pulling of the rovings they are led through a bath of liquid resin. After the application of the resin, the rovings are drawn by a norrowing mold gate, and finally through a heated mold which is equal to the desired diameter.
