Abstract: 
An experimental study was undertaken to investigate the influence of partial replacement of sand with quarry dust in the compressive strength and pull-out force of concrete. Four types of concrete, with two water-binder ratios of 0.40 and 0.45 were undertaken in this study. Replacement proportion of 20% sand with quarry dust was practiced in all the concretes except in the controlled concrete mix. All concretes were cured by dry air in the curing room at 20oC, and their compressive strength and pull-out force were measured on the 7th, 14th, 28th and 56th day. Test results indicates that concrete incorporating quarry dust and without the inclusion any mineral admixtures exhibited a lower compressive strength but a higher pull-out force than the controlled concrete at all ages. Inclusion of fly ash as 10% binder into the quarry dust concrete resulted in an increase in the compressive strength and pull-out force at almost all conditions. The quarry dust concrete incorporating 10% silica fume as binder exhibited the highest compressive strength and pull-out force in all conditions.
