SCC Produced with Recycled Concrete Aggregates

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 Get price
