SGU compiles annual statistics on the quantity of aggregates supplied from Sweden's licensed quarries. How much aggregate is needed in a year depends primarily on the economy, i.e., how much the construction sector is building. In the last few years, more than 80 million tonnes of aggregate materials were supplied from quarries.

Aggregates may be broadly classi fied as natural or artificial, both with respect to source and to method of preparation. Natural sands and gravels are the product of weathering and the action of wind or water, while manufactured crushed fine aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone.
aggregate production function: are the estimated coefficients (i.e., input elasticities, elasticity of substitution) the technological parameters?1 The main target of this non-technical survey is the new generation of economists, in particular those undertaking applied work. The reason is that, in the light of the conclusions

It was found that lightweight aggregates can be produced from fly ash using various techniques. Various methods associated with the production of these aggregates were mentioned in various literature works (Bijen 1986). It was found that the optimum dosage of water content for the fly ash aggregate production is around 20–25%.
It is important to know about aggregate planning while creating production schedule. Aggregate planning is the procedure of creating a production schedule for a given period. It starts after listing out all the requirements that are crucial for uninterrupted production. Aggregate planning covers elements like human resources, raw materials, …

In many applications, we want to understand how the aggregate production function responds to variations in the technology or other inputs. This is illustrated in Figure 16.9.An increase in, say, technology means that for a given level of the capital stock, more output is produced: the production function shifts upward as technology increases.
