Abstract

While recycled aggregates can replace natural aggregate in making concrete without compromising strength, it
is imperative to appraise the quality of the former. Quality of recycled aggregates depends upon the
composition and strength of concrete from which it is derived. Thus it is necessary to identify and evaluate
significant parameters characterizing a typical recycled aggregate. Adhered mortar present on recycled
aggregates has been observed to adversely affect the performance of aggregates in concrete, thus its removal
without affecting the properties of aggregate is essential. In this work a comparative study of various methods
for removal of adhered mortar content is carried out and an effective removal method feasible for use on field is
proposed.
