Abstract
In the mix proportion of shotcrete, it was analyzed as required in terms of eco-friendly technology to take advantage of the screenings. Screenings of recycling can be a solution in order to overcome the quality degradation due to the recent lack of good quality sand as well as the utilization of waste materials. Five regional screening and screening replaced fine aggregates for physical characteristics were analyzed to evaluate the usability screenings as shotcrete's combined aggregate. It was analyzed the effect of particle size distribution in the combined aggregate for shotcrete and maximum replacement was estimated according to the type of screenings.
