Use of ceramic wastes as aggregates in concrete
Irrespective of type, source, and replacement size of ceramic aggregates, the incorporation of ceramic aggregate in concrete causes a reduction in fresh and dry density of the resulting concrete due to the lower particle density and, in few cases, higher porosity of ceramic aggregates. 6.2.1. Plastic density.

Much less data was found on the physical and mechanical properties of FCS fine aggregate. From the available data, FCS fine aggregate appears to comply with the general requirement for concrete, such as particle size distribution and water absorption [49], [57]. As shown in Table 5, the value of fineness modulus is between 2.38 and 4.8. …

All About Coarse Aggregate: Types & Properties
Coarse aggregate is a term used in construction to describe a type of material that is commonly used in the production of concrete. It is typically made up of various materials such as gravel, crushed stone, and recycled concrete. The size of the coarse aggregate can vary, but it is typically between 3/8 inch and 1.5 inches in diameter.
