The largest-volume of recycled material used as construction aggregate is blast furnace and steel furnace slag. Blast furnace slag is either air-cooled (slow cooling in the open) or granulated (formed by quenching molten slag in water to form sand-sized glass-like particles). If the granulated blast furnace slag accesses free lime during hydration, it develops strong hydraulic cementitious properties and can partly substitute for portland cement in concrete. Steel furnace slag is also air-cooled. In 2006, according to the USGS, ai

quarry National Geographic Society
A quarry is a type of mine called an open-pit mine, because it is open to the Earth's surface. Another type of mine, a sub-surface mine, consists of underground tunnels or shafts. The most common purpose of quarries is to extract stone for building materials. Quarries have been used for thousands of years.
5 Aggregate Specifications and Requirements
this data is necessary on fine aggregate for other purposes, such as mix design and water/cementitious ratios. All aggregates are porous, but some are more porous than others. How porous an aggregate is determines how much liquid can be absorbed when soaked in water. The test method AASHTO T 85 defines absorption as
The Effect of Aggregate Properties on Concrete
The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material, aggregate, and water. Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete.
Study on Compressive Strength of Quarry Dust as Fine
Quarry dust is a byproduct of the crushing process which is a concentrated material to use as aggregates for concreting purpose, especially as fine aggregates. In quarrying activities, the Quarry dust is a byproduct of the crushing process which is a concentrated material to use as aggregates for concreting purpose, especially as fine aggregates. In quarrying activities, the rock has been crushed into various sizes; during the process the dust generated is called quarry dust and it is formed as waste.
