Some aggregates are made by combining fly ash and slag. Other types of aggregates are manufactured by recycling the construction waste from the demolition sites and are processed to get the desired shape. Later, these aggregates are screened and graded to meet the construction requirements. Uses of construction aggregate

Recycled aggregates (RA) from construction and demolition waste (CDW) instead of natural aggregates (NA) were analysed in the manufacture of new eco-friendly concrete.
