Concrete with organic mineral admixture based on fine grinding cooper slag

Abstract

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.
