ANALYSIS AND APPLICATION PROSPECTS EFFECTIVE RESOURCE SAVING TECHNOLOGIES IN CONCRETE

Abstract

Purpose. The purpose of this work is to study of reasons of unsatisfactory bearing capacity of existing reinforced concrete structures, analysis and structuring factors and environmental influences influencing the exploited structures of highway bridges and overpasses. Methodology. Consists in the analysis of the present operational condition concrete bridges. In the study and synthesis of technological and climatic factors affecting their operability in urban areas Findings. Based on these results it was given characteristics of the operational status of reinforce concrete bridges four Ukrainian regions with different types of climate. Based on the data on the technical condition of concrete bridges highlights the main features and specific operation of reinforced concrete structures in Dnepropetrovsk. Originality. Performed gradation reinforced concrete bridge constructions con depending on the duration of their operation. Comparative analysis of the elements of bridge structures on the operational status shows that about 80 % of bridges are in states 3 and 4. Practical value. In managing the technical condition of reinforced concrete bridges in the city of Dnepropetrovsk must take into account the joint effect of all the factors and groups will repay Business Plan environment operating on concrete structures. For such integration requires further research in the field of methodologies for assessing the performance and reliability of such facilities, taking into account the specifics of Dnepropetrovsk.
