 · Performance of Recycled Concrete Aggregates: A New Study. Posted on April 15, 2021. It is a basic axiom of environmental stewardship. When possible, use old stuff to make new stuff. The same is true with concrete aggregates. Mixes are more sustainable when recycled concrete aggregate (RCA) replaces natural aggregates, at least to a degree.

 · To reduce the cost of lightweight concrete (LWC) partition panels and to address recycling concrete waste, this work utilized completely recycled fine aggregate (CRFA) to replace the natural fine aggregate and ceramsite in the preparation of LWC and LWC partition panels. To this end, an autoclavefree curing process and an airentraining agent were used to prepare the CRFALWC.
