Ceramic fine aggregate (FCA) was used in substitution of 15% and 30% (in volume) of natural river sands for production of RC-15-FCA and RC-30-FCA high performance concretes, respectively. Due to the low density of recycled aggregates, the replacement of natural aggregates (both fine and coarse aggregates) was carried out …

Depending upon the size of the aggregate they can be classified into two categories as fine aggregates and coarse aggregates. 1. Fine Aggregates. The size of the fine aggregates is lesser than 4.75 mm. That is aggregates particles that passed through 4.75 mm. fine aggregates include things such as sand, silt, and clay.

The fine and coarse aggregates' physical properties are shown in Table 3. According to JGJ-52-2006 [22], the water absorption ratios and densities of both NA and CGA were tested. The elastic modulus of coal gangue was determined by cutting it into standard elastic modulus test blocks based on GB/T-50266-2013 [23].
