Sep 1, 2016 · In resourcepoor regions, using construction debris may facilitate economic, rapid, material sourcing and debris disposal if it demonstrates adequate structural performance. To investigate the seismic resistance of structural elements with recycled concrete aggregate, this research performs quasi-static cyclic testing on four full-scale ...
recycled concrete Topic
Oct 2, 2024 · Concrete debris is typically reclaimed as recycled aggregate (RCA). By recycling concrete, valuable landfill space and natural resources are preserved. This concept is part of the larger “sustainable construction” philosophy that seeks to minimize waste generation and encourage recycling in order to prevent adverse long-term environmental ...
Concrete preparation is the process by which sound, clean, and suitably roughened surfaces are produced in areas to be repaired.4 It includes delineating the repair boundaries by sawcutting; removal of unsound and, if necessary, sound concrete and bond-inhibiting foreign materials from the exposed concrete and reinforcement surfaces; opening the

DOI: 10.14359/13138. Date: 3/1/2004. Abstract: Recycled concrete aggregate (RCA), when used appropriately, is an excellent substitute for natural aggregates in highway construction. RCA has been used successfully in unbound applications such as base course and fill, and in bound applications as aggregate in new concrete.
