Investigation of Crushed Aggregate as Stemming Material in ...

Jul 12, 2015  The drill cuttings and crushed aggregates were used as stemming material (as shown in Fig. 1a, b) for conducting the trial blasts. The blast trials have been conducted in a lead–zinc mine, on the top overburden rock formations (Fig. 2a, b). The geology of the mine entailed a stratiform, sediment-hosted lead–zinc deposit that occurred in pre-Cambrian banded gneissic complex (BGC).

Selective quarrying solved the problem. In 1990, cracking deterioration was identified on a 3-year-old US-20 pavement in central Iowa. The coarse aggregate was a crushed limestone with an excellent history of performance in PCC pavement. Examination of cores showed very few cracks through the coarse aggregate particles.

Abstract. Concrete blocks of (15cm. x 20cm. x 40cm.) in size were cast using the crushed limestone( produced in large quantities in Al-molawatha region in north-east of Mosul city ) as coarseaggregate instead of the river gravel.Based on the experimental work of the present investigation, the followings may be drawn :1.
