Request (PDF) | Crushed aggregate pr. | Owing to the comprehensive building redevelopment programmes in Hong Kong, there is a huge volume of concrete waste generated that will soon exhaust all the available landfill areas. As such, recycled aggregate is advocated. However, the use of recycled.
New type of crushed sand to replace natural sand in concrete production. The availability of natural sand for concrete production is facing challenges, while the so-called waste stockpiles at aggregate crushing areas are causing problems for producers. This means that the industry has a huge need to solve this challenge.
Crushed stone is produced in every state in the U.S. except Delaware. The type of crushed stone mined from any particular state depends on the general geology and rocks of the state. For instance, crushed line and dolomite are typical in Indiana, Illinois and Ohio, whereas marble and granite come from Vermont.

SGU statistics show how much aggregates have been supplied every year since 1984. At that time, natural gravel was the most common material, constituting about 80 per cent of aggregates production. Today, the situation is reversed, with more than 80 per cent consisting of crushed rock. SGU's periodical publication.
