Removal of Adhered Mortar from Recycled Aggregates
Abstract: While recycled aggregates can replace natural aggregate in making concrete without compromising strength, itis imperative to appraise the quality of the former. Quality of recycled aggregates depends upon thecomposition and strength of concrete from which it is derived. Thus it is necessary to identify and evaluatesignificant parameters characterizing a typical recycled aggregate. Adhered mortar present on recycledaggregates has been observed to adversely affect the performance of aggregates in concrete, thus …
