What are recycled and secondary aggregates,

Secondary aggregates are usually by-products of other industrial processes that have not previously been used in construction. Secondary aggregates can be further sub-divided into 'manufactured' and 'natural', depending on their source. Examples of manufactured secondary aggregates are pulverised fuel ash and metallurgical slags. Natural secondary aggregates include china clay stent and slate,Recycled & Secondary Aggregates,The UK utilises 70 mt of recycled and secondary materials in the GB aggregates market, this contributes 28% market share which is three times higher than the European average, highlighting the fact that the use of recycled and secondary materials in Britain is close to full potential. Recycled aggregates . Construction will often require demolition of existing buildings and structures built,Secondary Aggregates | Dudman Group of Companies,Secondary aggregates are recycled waste streams from primary manufactured or recycled products and can be used as well as or in replace of primary aggregates.
