Fifty Merino weaner sheep grazing on a wheat stubble at Wongan Hills were fed ad lib. either oat grain mixed with limestone (2% w/w) or just oat grain during the summer and autumn of 1985. The addition of limestone to the oat supplement increased the growth of the sheep from 39 g/day to 83 g/day (P<O.OOl) during the first 70 days of feeding. A summer thunderstorm resulted in a brief germination...

The Christmas copper mine is in the Banner mining district, Gila County, Arizona. It is 8 miles north of Winkelman and 22 miles south of Globe. The mine was opened in 1905; to the end of 1943 it had produced about 55,340,000 pounds of copper. In 1946 it was operated under lease. The ore is high-lime fluxing ore, required by the smelter at Hayden. The ore produced during 1942 averaged 2.16 perce...

The feasibility of using waste brick powder (WBP) in the manufacture self-compacting mortar has been investigated this study. limestone filler was partially or totally (0%, 50% and 100%) substituted with WBP. rheological properties, compressive flexural strengths, drying shrinkage durability properties (including carbonation resistance, chloride ion diffusion sulphate resistance) mortars were e...

To improve sustainability and reduce costs, interest in using limestone powder (LP) ultra-high performance concrete (UHPC) has been increasing recent years. Incorporating LP changes packing, characteristics of C–S–H pore structure interfacial transition zone (ITZ) matrix by physical chemical effects. However, the influences replacement on mechanical properties UHPC, from micromechanics to macro...

Since ages, architects and artists worldwide have focused on usage of durable stones as marble and limestone for construction of beautiful and magnificent historic monuments as European Cathedrals, Roman, and Greek temples, Taj Mahal etc. But survival of these irreplaceable cultural and historical assets is in question these days due to their degradation and deterioration caused by number of bi...

Analyses of samples of the raw materials locally available for use in the Eaton (Hopewell) Furnace indicate that the iron ore and bituminous coal were of good smelting quality while the limestone (flux) was not. The limestone had a much higher then desirable silica content and a low calcium content. The limestone was insufficient to the task of removing impurities introduced through the fuel co...
