Sep 24, 2020 In the Iraqi Kurdistan Region, as well as, other parts of the Iraqi territory, chert was not used previously in the cement production since very, high quality, quartz-sand occurs in the Iraqi Western Desert (Muradian 1985; Al-Bassam 2013). However, due to difficulties in transporting quartz-sand from the Erdhuma quarry to the Kurdistan Region and security concerns, chert of the Qulqula Group has recently been used as an alternative for the quartz-sand in cement production

Dec 01, 2000 Four types of natural quartz sand are used for producing GQS with the Blaine specific area of 283–551 m 2 /kg, having SiO 2 content of 99%, 94.5%, 92.1%, and 84.7%, respectively. The GQS with 92.1% SiO 2 is from the same sand as the river sand for preparing concrete. A naphthalene sulfonate superplasticizer, Mighty 100, is used for making the concrete

Industrial sand and gravel, often called silica, silica sand, and quartz sand, includes sands and gravels with high silicon dioxide (SiO2) content. These sands are used in glassmaking; for foundry, abrasive, and hydraulic fracturing (frac) applications; and for many other industrial uses. The specifications for each use vary, but silica resources for most uses are
