The present study was designed to explore the applicability of dolomite dust (a waste from a quarry) as filler in polymer composites. Therefore, fixed carbon fiber reinforced vinyl ester composites with varying proportions (0, 5, 10 and 15 wt.%) are manufactured subsequently evaluated for physicomechanical sliding wear properties. Experimental results indicate that density, void content, impact...

This work demonstrates the usage of two new quartz instruments, which are a tiltmeter and an extensometer that we developed lately to measure with high accuracy deformations of structures, volcanoes, tunnels, and ground surface. The stability of an underground quarry, near Paris in France was the subject of the study. The deformation of the quarry under different cases of loading during the pro...

This paper reports the corrosivity and leaching behavior of CLSM made using two different industrial wastes i.e. bottom ash from an incineration facility and quarry dust. The leachate samples were derived from fresh and hardened CLSM mixtures, and studied for leaching and electrical resistivity. The release of various contaminants and the consequent environmental impact caused by the contaminan...

In 1978 a study of the mortality of United States cement plant and quarry workers was initiated. The vital status of a cohort of 5292 men who had been employed for at least five years in a cement plant between 1950 and 1980 was traced to 1 January 1980. The mortality experience was evaluated for 4231 white men for whom complete work histories and demographic information were available. Deaths f...
