Oil Sands 101: Process Overview | Oil Sands Magazine
· Oil sands are actually found all over the world, and are sometimes referred to as tar sands or bituminous sands. A typical oil sands deposit in Alberta contains on average about 10% bitumen, 5% water and 85% solids, mostly in the form of coarse silica sand. Oil sands also contain fine solids and clays, typically in the range of 10 to 30% by weight.
Why 2,000 YearOld Roman Concrete Is So Much Better Than ...
· In concrete, this paste binds 'aggregate' chunks of rock and sand. This aggregate has to be inert, because any unwanted chemical reaction can cause cracks in the concrete, leading to erosion and crumbling of the structures. This is why concrete doesn't have the longevity of natural rocks. But that's not how Roman concrete works.
