Fiber strength is measured by breaking the fibers held between clamp jaws. It's reported as grams per tex, which is the force in grams required to break a bundle of fibers one tex unit in size. A tex unit is equal to the weight in grams of 1000 meters of fiber. Nep A nep is small tangled knot of cotton fibers.

For example, depending on the region of the United States, crushed stone in the size of a few mm to 2 inches is referred to as "gravel," even if it has been crushed and is no longer smooth. To provide clarity and avoid confusion, we will stay with the definition that gravel cannot refer to crushed stone and must remain in a natural state.

Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel. Crushed air-cooled blast-furnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected.
