Abstract: Increasing shortage of natural aggregates for concrete in urban areas leads to a search for aggregates from new sources. This paper examines the use of crushed concrete fines (CCF) produced from 'waste' concrete as fine aggregate in concrete. Tests were carried out to study the properties of crushed concrete fines and the properties of concrete incorporating them. The results show that the modulus of elasticity, pulse velocity, and the long-term properties such as drying shrinkage and creep are significantly affected. It has been found that the detrimental effects of using crushed concrete fines in concrete can be mitigated by a partial replacement of crushed concrete fines with pulverised fuel ash (pfa). © 1987.
