Analysis and projection of the compressive strength of concrete, using fine and coarse aggregates of construction and demolition waste (CDW) from the EMAVERDE pilot plant

This research analyzes the results of the incorporation of aggregates from construction and demolition waste (CDW) processed in the first pilot CDW transformation plant in Bolivia, located in the city of La Paz, and its incorporation into a new mixture. with natural crushed aggregates, in addition to its projection at higher substitution percentages, to propose a formula that can predict its behavior. The natural aggregate was replaced in percentages of 0%, 30% and 60% by RCD coarse aggregate, making a total of 45 specimens. In addition, specimens were made partially replacing the fine aggregate in proportions of 0%, 25%, 50%, making 51 specimens, the natural aggregates used were characterized and verified for their use in concrete, the specimens made were compression tested after 7, 14 and 28 days.
