Aggregate is the main ingredient in Portland Cement Concrete and Asphalt Concrete. All aggregate used for construction purposes must be tested, physically and chemically, to verify its suitability for these uses. Every potential production site must be tested to ensure that the materials meet specifications for a particular application and to ...

The Aggregate Production Function is the function that shows a technical relationship between aggregate inputs and aggregate outputs. It is a mathematical model that economists use to illustrate the change in productivity because of the changes in factors of production. It helps an economy to produce its potential level of output.

In the quarry, crushing is handled in four potential stages: primary, secondary, tertiary and quaternary. The reduction of aggregate is spread over these stages to better control the product size and quality, while minimizing waste. The primary stage was once viewed merely as a means to further reduce stone following the blast or excavation ...

Recycled material such as blast furnace and steel furnace slag can be used as aggregate or partly substitute for portland cement. Blast furnace and steel slag is either air-cooled or water-cooled. Air-cooled slag can be used as aggregate. Water-cooled slag produces sand-sized glass-like particles (granulated).

The general idea is that the smaller the aggregate size, the more we need equipment to produce it. Production of aggregate starts typically from 800 mm pieces of blasted material. One crusher can only reduce the size by a certain amount. For example, manufactured sand is a very fine product with high quality requirements.
