(Elsevier Sci Ltd, 2018)
The objective of this study is to observe the radiation shielding efficiency of concrete produced by using the lead wastes that are stored in lead-zinc mines processing of which is not financially viable in the mines they ...
Utilization of granulated marble wastes and waste bricks as mineral admixture in cemented paste backfill of sulphide-rich tailings
(Elsevier Sci Ltd, 2015)
This study presents the utilisation of granulated marble wastes (MW) as an additive (10-30 wt%) and waste bricks (WB) as replacement and additive (15-45 wt%) to ordinary Portland cement (OPC) for cemented paste backfill ...
Nature of tourmaline formation in quartz porphyry in the E Sakarya zone (NE Turkey): geochemistry and isotopic approach
(Edizioni Nuova Cultura, 2019)
Tourmaline, which exhibits important differences in terms of texture and composition, is found in 44 My aged quartz porphyry from Karadag in the eastern Pontide (NE Turkey). Tourmaline has high Al and Mg contents and is ...
Effects of Mn Content on Microstructure, Mechanical and Dry Sliding Wear Properties of Eutectic Al-Si-Cu Alloy
(Korean Inst Metals Materials, 2020)
In the present study, effects of Mn content on microstructure, hardness, tensile and dry sliding wear properties of eutectic Al-Si-Cu alloy in as cast-state were investigated. Mn addition to the eutectic alloy results in ...
