ACI Material Journal 网页1 天前 Additionally, it has been noted that quarry dust sold as M−Sand contains a higher percentage of micro fines (particles smaller than 75 µm) and flaky particles, both of which have an impact on the calibre of concrete and other construction projects [16], [17]. 网页2022年3月8日 QD consists of excess fines and is considered as a waste material which is normally dumped in bulk quantities around the quarry plants and causes environmental pollution. QD has been used successfully in concrete and in controlled low-strength material [1-3]. Quarry dust has been used for different activities in 网页2 天之前 Devri stone quarry dust is a waste byproduct that should be utilized in all construction projects to prevent environmental harm from its disposal. This quarry dust is produced in large quantities by the stone dressers who create Kashmiri hamams (rooms with hollow bottoms where fire is burned to produce heat) and other stoneware artifacts. 网页2023年2月7日 Sridharan .
