Almost 2–3 t of copper slag is generated as residual product per ton of copper product, according to the performance of the copper concentrates and the operational condition during the pyrometallurgical process. The yield of slag reaches nearly 70 million tons each year worldwide (Radetzki, 2009; Shi et al., 2008).

The accelerated carbonation technique of steel slag has many links and complicated operations. The grinding energy consumption of steel slag is 36.7 kWh/ton, and the laboratory accelerated carbonation cost of steel slag powder is 42.1 $/ton . Therefore, cost control will be a key issue after this method is applied to production.

Most gravel weighs 1.4 to 1.7 tons per cubic yard. See below for more common material densities. For example, let's find the amount of gravel needed for a space that is 10 feet long, 10 feet wide, and 1 foot deep. volume = length × width × depth volume = 10′ × 10′ × 1′ = 100 cu ft cu yds = 100 cu ft / 27 = 3.7.

A solid, unbroken slab of concrete weighs about two tons (or 4,000 pounds) per cubic yard. Breaking up concrete roughly halves the total weight per cubic yard to about one half ton (or about 2,000 pounds). How many bags of concrete are in a yard? To produce one yard of concrete, you'll need to use about 45 80-pound bags (or 90 40-pound bags).
