Subject: applying mineral microfillers on the basis of technogenic wastes of non-ferrous metallurgy in the technology of cast and self-compacting concrete. The results of experiments of scientists from Russia, Kazakhstan, Poland and India show that copper smelting granulated slag can be used when grinding construction cements as a mineral additive up to 30 % without significantly reducing activity of the cements. However, there are no results of a comprehensive study of influence of the slag on plastic concrete mixtures. Research objectives: establishment of mathematical relationship of the influence of copper slag on the compressive strength and density of concrete after 28 days of hardening in normal conditions using the method of mathematical design of experiments; statistical processing of the results and verification of adequacy of the developed model. Materials and methods: mathematical experimental design was carried out as a full 4-factor experiment using rotatable central composite design. The mathematical model is selected in the form of a polynomial of the second degree using four factors of the response function. Results: 4-factor mathematical model of concrete strength and density after curing is created, regression equation is derived for dependence of the 28-days strength function and density on concentration of the cement stone, true water-cement ratio, dosage of fine copper slag and superplasticizer on the basis of ether polycarboxylates. Statistical processing of the results of mathematical design of experiments is carried out, estimate of adequacy of the constructed mathematical model is obtained. Conclusions: it is established that introduction of copper smelting slag in the range of 30…50 % by weight of cement positively affects the strength of concrete when used together with the superplasticizer. Increasing the dosage of superplasticizer in excess of 0.16 % of the dry component leads to a decrease in the strength of cast concrete. The developed compositions of cast fine-grained concrete mixtures can be used in high-density reinforcement concrete structures with strict requirements for size of fillers and plasticity of mixture.

The problem of applying copper manufacturing wastes locating in Chelyabinsk region as a component of organic mineral admixture for concrete with industrial wastes production is considered in this article. Also, organic mineral admixture consisting of superplasticizers, based on esters with carboxyl groups, has not yet been sufficiently studied due to the diversity of species and the complexity of chemical structure. This trend is current for today’s science because of the growing rates and scales of building production, in particular, concrete works. Using new complex admixtures processed of industrial by-products showed their effectiveness. Copper slag dumps located in Urals federal district haven’t been widely used in building production or in other industrial production up to the present time. Efficient utilization of copper production waste materials will help to solve the ecological problems in most regions of Russia. The structure formation period of cement stone with organic mineral admixture, based on fine grinding cooper slag and superplasticizer, is also studied in the article. The thermal variation diagram of concrete mixture with organic mineral admixture during 22 hours of hardening under normal condition are shown and the results of ultrasound of concrete forming structure period during 6 hours of hardening are presented in this article. The strength development process diagram of concrete with organic mineral admixture during 28 days of hardening under normal condition and the research results of the compressive strength of concrete samples are also presented. The obtained characteristics confirm the prospects of applying this kind of non-ferrous metallurgy wastes in the concrete. Also, the obtained results allow us to conclude the significant advantages of using this kind of complex admixture for concrete production with different purpose and in different fields of application.

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.
