Mechanical behavior of concrete containing recycled aggregates

Increased demand and decreased supply of aggregates for concrete production necessitate the search for new aggregate sources. Environmental features are increasingly being used to evaluate construction materials. Concrete recycling is becoming more popular since it conserves natural resources and reduces the need for disposal by using readily available concrete as a source of aggregate for fresh concrete. Several studies on the influence of recycled aggregate on the engineering qualities of concrete have been conducted. This investigation was carried out using the use of recycled aggregate as a form of modification. When it comes to the use of recycled aggregate, the percentage of recycled aggregate should be decided. This is because a large proportion of recycled aggregate would not allow for the achievement of the desired level of strength in the concrete. The purpose of the research is to evaluate the similarities and differences between natural aggregate and recycled coarse aggregate with regard to specific gravity, apparent specific gravity, absorption, and Los Angeles. In addition, the comparison of recycled aggregate with 0% replacement, 35% replacement, 50% replacement, and 65% replacement will be the emphasis of this study.
