Abstract
Aim. Disposal of industrial waste to improve the environmental safety by means of recycling and reusing in the manufacture of building materials.
Materials and methods. We made a selection of new optimum compositions of fiber-concretes using industrial carbon black from heat generating productions, glass fibers, plasticizers, activated mixing water produced using an ultrasonic unit.
Results. New fiber-reinforced concrete compositions were developed using carbon black as an additive. As a result of the processing of the experimental data, it has been revealed that introduction of carbon black as an additive contributed to the increase of the strength characteristics of nearly all fiber-reinforced concrete compositions. It has been found that microparticles of carbon black accumulate the products of hydration of portlandcement-hydrosilicate calcium on the surface and contribute to the formation of a solid microarming concrete structure.
Conclusions. The use of industrial carbon black in fibrous concrete mixture using restructured water improves its rheological properties, reduces its segregation and improves the homogeneity of the concrete. Recycling and re-using carbon black in the production of building materials will improve the environmental ecology.
