Abstract

The presence of cement paste is the most important factor affecting the quality of recycled concrete fine aggregates. This study aims to develop the thermo-chemical treatment for the purpose of removal of the cement paste adhering to recycled concrete fine aggregates. This study involves assessing the effectiveness of thermo-chemical treatment and comparing its efficiency with thermal and chemical treatments. The results of the investigation elucidate the influence of these treatments on the performances of recycled concrete fine aggregates as well as influence of using treated and untreated recycled concrete fine aggregates on the characteristics of concrete. The results revealed that the thermo-chemical treatment experiences the satisfactory performances in improving the quality of recycled concrete fine aggregates and such treated recycled concrete fine aggregates used in concrete contribute to considerable improvement in strength characteristics.
