The possibility of using materials based on secondary gravel in civil construction

Abstract

Abstract. By now, the wear and tear of housing stock is more than 50%. Each year the number of old and dilapidated housing is growing, but it is gradually replaced by modern buildings. However, wastes accumulated from dismantling of buildings and constructions, are underutilized and, usually are just stored at landfills, or used for temporary roads construction. The purpose of this research is to define construction wastes characteristics and to explore possibilities for recycling of wastes from construction materials production. The paper also analyzes housing stock condition and basic requirements to building materials used in construction; and demonstrates results building materials based on secondary gravel investigation. While working with materials based on waste requirements the authors conducted laboratory research. Thus, the paper presents the analysis of laboratory tests results that made it possible to draw conclusions about the possible use of building materials based on secondary gravel and about their conformity to specified requirements. The researchers also developed proposals and recommendations to improve the competitiveness of such materials.

Efficiency of construction waste recycling

“…The conducted studies of the resulting broken concrete quality showed sufficient strength of the resulting building products [13] for their use in the construction of new buildings and structures or as a concrete filler for reconstruction of hydraulic structures. Such use of concrete waste will reduce the volume of extracted natural resources, decrease the load on landfills, and also minimize the logistics costs for the transportation of waste and natural resources.…”
