The aim of this research is to analyse how the crushing process influences aggregate shape properties. Form, angularity and surface texture of five coarse and five fine aggregates, from three different quarries, were evaluated by means of digital image processing and were categorised by two different classification systems.

There is a general belief that crushed aggregates contribute higher strength in concreting compared to rounded aggregates. Contrary to this belief, our study revealed: rounded aggregates perform better than crushed aggregates because the rounded shape which considered as a negative characteristic is compensated by.

Primary crushing - scalping pre- or post-crushing, primary surge pile. • Secondary crushing (& further stages) – cone & impact. • Screening - production of aggregate products inc. quarry fines, recirculation/ recrushing of oversize & coarse aggregate. • Stockpiling - uncovered or covered. • Handling/ distribution/ transportation.
make good secondary crushers. Washing. Most coarse aggregates and some fine aggregates can be rinsed over a vibrating inclined screen with a pressure spray nozzle (Barksdale, 2001). Washing the aggregate reduces the clay- sized particles (excessive dust) and other deleterious materials (Roberts et al., 1996).
The present Investigation has been undertaken to study the effect of blast furnace slag and crusher dust on the mechanical properties of concrete, when coarse aggregates is replaced by blast furnace slag and crusher dust is replaced with fine aggregate in different percentages i.e. 0%, 10%, 20%, 30%, 40%, 50%, 60%,.
