Geothermal and solar pv are future energy sources, as both these renewables draw energy from natural heat sources i.e. the Earth and the Sun. While geothermal energy utilizes Earth's heat for power generation and for direct applications, like space cooling and dehydration, solar energy captures the Sun's energy and converts the …

Quartz Sandstone. Quartz sandstone is a common and often large cobble to boulder-size clast component in Pre-loess Terrace Gravels. These sandstones are often white to grey and have a sparkling appearance to them due to cementation by quartz overgrowths. Some varieties are feldspathic, and some are green from the presence of the mineral chlorite.

Sandstone quarrying is a highly polluting activity which produces a huge amount of dust and waste slurry emissions. Sandstone quarrying dust and wastes were found to be polluting nearby agricultural land and severely affecting the health of quarry workers (Ahmad, 2015; Singhal and Goel, 2020).A time-series study conducted on the …

Quartz crystals are oxide minerals with the trigonal or hexagonal system, whose cell parameters are: a = 4.916 Å, b = 4.916 Å, c = 5.405 Å. The Si-O bond angle in α-quartz is 144° and the bond length is between 0.16101 and 0.16145 nm ( Götze, 2009 ). The different types of quartz crystals are shown in Table 1.

Concrete mechanical properties could be improved through adding different materials at the mixing stage. Quarry dust (QD) is the waste produced by manufactured sand machines and comprise approximately 30–40% of the total quantity of QD generated. When it dries, it transforms into a fine dust that poses a tremendous hazard to the …
