Use of concrete scrap as a coarse aggregate for reinforced concrete products

Abstract

In this paper, an experimental study was conducted to compare the properties of aggregateobtained from destroyed concrete waste, laboratory concrete waste and natural aggregatesused as control samples. The study examines the possibility of using demolition waste to develop building materials with sustainable properties in order to obtain economic benefits from the disposal of man-made waste. Initially, the selection of aggregates from waste was carried out by crushing concrete fragments from demolition waste and laboratory waste, and then studying their physical and chemical properties to obtain fillers and concrete mixtures, make samples, and determine compressive strength. The correlation between the results of various experiments was analyzed and a linear correlation was established between the compressive force and other established mechanical properties. The possibility of recycling construction waste is presented, which leads to the solution of several problems: reducing the cost of processing industrial waste and improving the physical and mechanical properties of concrete due to their introduction as a filler.
