11.3.1 Recycled aggregates. As concrete production keeps on increasing worldwide, so does the use and consumption of abiotic resources, such as aggregates. To corroborate this statement, the worldwide aggregates demand will raise from 45.9 to 66.3 Gt in a time span of 10 years (e.g., 2012–22) (Freedonia, 2012). Another clear indicator of the use and growth of concrete is related to cement ...

Development Of Light Weight Concrete - Civil Engineering

It is produced by including large quantities of air in the aggregate, matrix or in between the aggregate particles or by a combination of these processes. Lightweight aggregates require wetting prior to use to achieve a high degree of saturation. If the aggregates aren’t fully saturated they have a tendency to float towards the surface of the mix after it has been placed.
