Abstract
At present, developing and improving low-material, energy- and resource-intense technologies to manufacture concrete and reinforced concrete products and structures have become a topical issue in the construction industry. Therefore, centrifugation technology is promising. In this article, the formu-lation of concrete with variatropic structure was improved, and the methods for its qualitative and quan-titative assessment were developed. Seven annular cross-section reference samples were manufac-tured and tested. Based on the test results of centrifuged concrete samples with different grain size compositions of the coarse aggregate, the empirical values of the integral and differential strength and deformation characteristics of concrete were determined. The structural and stress-strain variational efficiency coefficients were calculated and analysed. The optimal grain size composition of the coarse aggregate was determined and allows centrifuged concrete with an enhanced variatropy to be ob-tained, as well as the most effective coefficient of variatropic efficiency. The prospects for further en-hancing the variatropy of centrifuged and reinforced concrete products and structures by improving the formulation-technological factors were determined.
