Quarrying and processing of granite produce large amounts waste residues. Besides being a loss resources, improper disposal these wastes results in pollution the soil, water air around dumpsites. The main components are quartz, feldspars small amount biotite. Due to its hard dense texture, high strength, corrosion resistance wear resistance, may be recycled into building materials, composite ma...

Saturated [K s ], field saturated [K fs ] and unsaturated [K(ψ)] SUMMARY There is increasing interest in the landspreading of slurries, sludges, effluents and fertilisers, resulting from the need to recycle increasing volumes of waste from high production agriculture units, old and new sewage treatment works and industrial facilities. Wastes should be spread only on suitable unsaturated soils a...

In this work, the waste stone sludge obtained from the granite and marble stone processing factories was used for the manufacture of artificial stones using vibratory compaction in a vacuum environment. The results obtained showed that water absorption and density increased, and the flexure, compressive, and tensile strengths decreased with increase in the content of the waste stone sludge. The...

Previous research examining radon exposure from granite countertops relied on using a limited number of exposure scenarios. We expanded upon this analysis and determined the probability that installing a granite countertop in a residential home would lead to a meaningful radon exposure by performing a Monte Carlo simulation to obtain a distribution of potential indoor radon concentrations attri...

The dissolution of minerals plays an important role in the formation of soils and sediments. In nutrient limiting soils, minerals constitute a major reservoir of bio-essential cations. Of particular interest is granite as it is the major rock type of the continental land mass. Although certain bacteria have been shown to enhance weathering of granite-forming minerals, little is known about the ...

In order to better understand the role of the uid behavior in CMP, we measured slurry transport beneath a glass wafer. We quanti ed the slurry transport using Residence Time Distribution techniques and two measures of slurry transport e ciency de ned as the percentage of new slurry beneath a wafer. Slurry transport e ciency depended on platen speed, ow rate, and the conditioning method. We foun...

The Boundary Element Method has been applied to calculate stress distribution and stability of underground mines for disposal of chemical waste. A case similar to the Stripa mine in Sweden has been considered. The rock mass was granite, with major fracture zones represented by three families of planes mutually orthogonal and 100 meters distant from each other. The pre and post processor GiD [3]...
