Scoria Vineyards ready to rock Idaho wine industry

When her plantings span 100 acres and come into full production, Scoria Vineyards could easily reach 20,000 cases worth of wine. Split among Koenig and Telaya wineries, Scoria might be a 10,000-case brand. And Nederend will only be in her early 30s. "The marketing and design aspect is what I really love," she said. Aerolite's scoria aggregates weigh about half that of comparable dense aggregates without sacing quality. Weighing in between 750 to 850 kgs per M3. That means on average you will only need to purchase half the amount of scoria when compared to a dense weight aggregate to complete the same job.

Scoria ~ Learning Geology

Scoria is a highly vesicular, dark coloured volcanic rock that may or may not contain crystals (phenocrysts). It is typically dark in colour (generally dark brown, black or purplish red), and basaltic or andesitic in composition. Scoria is relatively low in density as a result of its numerous macroscopic ellipsoidal vesicles, but in contrast to pumice, all scoria has a specific gravity greater ... Uses Of Scoria. Creating concrete: Concrete made with typical sand and gravel weighs about 150 pounds per cubic feet while concrete made with scoria is approximately 100 pounds per cubic feet. The decrease in weight when using scoria allows the construction of buildings to contain less structural steel.
