Particle Packing Method of Mix Proportioning and Modified Mixing Approach

One of the main industries responsible for the rapid depletion of natural resources and the production of greenhouse gases in order to obtain the essential raw materials is the construction industry. To ease the strain on natural aggregate mining, aggregates, which make up around 70—80% of the volume of concrete, must be replaced with a sustainable alternative. Additionally, the construction industry and the generation of C &D trash go hand in hand. Natural aggregate can potentially be replaced with recycled aggregate (RA), which is produced from leftover concrete from the C &D waste. RA can be divided into RCA and RFA categories according to size. The use of RCA alone for structural concrete preparation is the exclusive focus of this work.
