SCC Produced with Recycled Concrete Aggregates

Abstract:

The major content in concrete is aggregates. Reduce its usage and replaced with recycled concrete aggregate (RCA) could not only mitigate consuming of natural resources but avoid the treatment of solid wastes. Furthermore, producing self-compacting concrete (SCC) with RCA is a way for traditional construction industry in saving energy and avoiding noise emission. To seek the proper way in preparation of SCC with RCA, preparation of RCA, composition design, microstructure evolution with hydration, and mechanical properties are investigated within this study. It is found that successful producing of SCC with RCA is not a complicated process.
