The problem of applying copper manufacturing waste locating in the Chelyabinsk region as a component of mixed is considered in this article. Application of mixed binder with superplasticizers, based on esters with carboxyl groups, have not sufficiently been studied by the present time due to the diversity of species and complexity of the chemical structure. This trend is current for today’s science because of the growing rates and scales of building production, in particular, of concrete works. Copper slag dumps located in the Ural Federal district haven’t been widely used in building production or in other industrial production by the present time. Efficient utilization of copper production waste materials will help to solve ecological problems in many regions of Russia. Structure formation period of cement stone based on mixed binder made of Portland cement and granulated cooper slag with application of superplasticizer is studied in the article. The authors present a thermal variation diagram of mortar based on mixed binder made of Portland cement and granulated cooper slag in the process of 21 hours of hardening under normal conditions and the results of ultrasound investigation of concrete structure formation period during 5 hours of hardening. The strength development process diagram of mortar based on mixed binder made of Portland cement and granulated cooper slag for 28 days of hardening under normal conditions and the research results of the compressive strength of concrete samples are shown in this article. The obtained characteristics don’t confirm the prospects of applying joint grinding for mortar with the observed kind of non-ferrous metallurgy waste. Also, the obtained results allow us to make a conclusion about little advantages of using this method of binder production. Copper slag can be more effectively used as a component of complex organic and mineral admixture for building production with different purposes and fields of application.

The authors consider a problem of the influence of copper manufacturing waste locating in the Chelyabinsk region on concrete porosity when applying it as an independent mineral admixture and as a component of organo-mineral mixed binder for production of concrete with industrial wastes. This trend is current for today’s science because of the growing rates and scales of building production, in particular, of concrete works. Also complex organic mineral admixture consisting of superplasticizers, based on esters with carboxyl groups, and fine grinding copper slag have not been studied by the present time due to the diversity of species and the complexity of chemical structure. Using new complex admixtures and mixed binders processed of industrial by-products showed an high index of their effectiveness. Copper slag dumps located in the Urals federal district haven’t been widely used in building production or in other industrial production by present time. Efficient utilization of copper production waste materials will help to solve ecological problems in most regions of Russia. The results of the study of different porosity groups (pores of different diameter) were presented on porosity development process diagrams depending on the volume of introduction of fine copper smelter slag in concrete with cooper mineral admixture and strength-porosity correlation diagrams. The obtained characteristics don’t confirm the prospects for applying method of joint grinding of concrete with this kind of non-ferrous metallurgy waste. In addition, the obtained results allow us to make a conclusion about little advantages of using this method of binder production. Copper slag can be more effectively used as a component of complex organic and single mineral admixture for concrete production with different purposeы and fieldы of application.
