Properties of recycled coarse aggregates made of concrete waste

Abstract

EN: During the post-war reconstruction, Ukraine will face the challenge of dealing with a large number of buildings and structures that will be subject to partial dismantling and demolition. According to the Kyiv School of Economics as of January 2024, the losses from the destruction and damage of buildings and structures amount to at least 75 billion dollars. The issue of the general level of physical depreciation of buildings and structures is also relevant for Ukraine, both in the industrial and civil-residential sectors. The development of construction contributes to an increase in the volume of demolishing old buildings and structures, which, in turn, leads to the emergence of a large amount of construction waste. On the other hand, there will be a need for a large amount of materials for renewal, the share of which can account for up to 50 % of the construction cost. To reduce the cost of projects, it is advisable to reuse materials from waste generated after dismantling. In 2022 new standard was implemented regulating the handling of waste resulting from armed conflicts. Now contractors carrying out the liquidation of the consequences of armed aggression are required to take measures to reuse construction waste.
