Exploring Concrete Scrap as a Promising Building Material for Restoration Ukraine’s Transport Infrastructure

This paper investigates the possibility of using concrete scrap as a filler in the manufacture of concrete and reinforced concrete products as promising alternative building materials. These products will be used to restore the transport infrastructure of Ukraine as cost-effective substitutes for traditional road building materials. To study the issue of physical, mechanical and technical properties of concrete scrap, a number of tests were carried out. The study aimed to determine the possibility of using concrete scrap as an aggregate in the manufacture of concrete products without deteriorating the physical mechanical, construction, and technical properties. The article analyses the existing experience in the use of secondary crushed stone. Based on this, it can be seen that concrete scrap is actively used in construction. The advantage of using it is also a reduction in the cost of work and profitability. The authors carried out experimental studies to study the physical and mechanical properties of crushed stone-sand mixture and concrete based on aggregate from concrete scrap.
