2021年7月17日 Dolomite industrial waste is generated mainly due to the crushing and processing of dolomite stone during mining and production activities. Chemical properties. Cohen et al. studied the effect of waste dolomite quarry dust waste (QD) as a filler material in cement and fly ash-based geopolymeric mixtures. The fresh properties of the mixtures
Because the dolomite is mainly used in the region where the authors are located, the manufactured sand obtained from dolomite crushing was chosen as fine aggregate in this . To avoid the effect of stone dust content in the manufactured sand on the flow properties of the mortar, the manufactured sand samples were sieved and cleaned in the
2023年3月27日 Dolomite (CaMg(CO 3) 2) precipitation is kinetically inhibited at surface temperatures and pressures. Experimental studies have demonstrated that microbial extracellular polymeric substances (EPS) as well as certain clay minerals may catalyse dolomite precipitation. Atmospheric dust may have also contributed a considerable
2021年5月2日 Dolomite is a naturally occurring mineral complex that contains varying quantities of quartz (crystalline silica). In its natural bulk state, dolomite is not a known health hazard. Dolomite may be subjected to various natural or mechanical forces that produce small particles (dust) which may contain respirable crystalline
2013年11月8日 About three-quarters of the crushed stone production is limestone and dolomite, followed by, in descending order of tonnage: granite, traprock, sandstone and quartzite, miscellaneous stone, marble, slate, calcareous marl, shell, volcanic cinder and scoria. Limestone, one of the largest produced crushed rock, is a sedimentary rock
2023年4月5日 The temporal pattern of water–rock interaction is significant in predicting the ion concentration of the effluent in coal mine underground reservoirs. This study used the roof-caved rock samples and main incoming water (mine water and fissure water) of the Daliuta coal underground reservoir as the research object and designed four groups of
2020年12月7日 For the first time, it is shown that inhaled ambient air-dust particles settled in the human lower respiratory tract induce lung calcification. Chemical and mineral compositions of pulmonary calcium precipitates in the lung right lower-lobe (RLL) tissues of 12 individuals who lived in the Upper Silesia conurbation in Poland and who had died
2023年3月29日 The stone crushing equipment are used to produce aggregate of limestone, granite, basalt, river stone, marble, iron ore, dolomite, quartz, slag etc, which is widely applied for hydropower, construction, highway, railway, airport runway, civil engineering projects and etc. Features: 1. Low operating cost and high crushing rate; 2.
