Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete.

Traditionally, "polymer processing" has been analyzed in terms of specific processing methods, such as extrusion, injection molding, compression molding, calendering, etc. Table 1 summarizes processing methods applicable to thermoplastics and thermosets, as well as methods common to both types of materials.
Details. aggregate is a generic function with methods for data frames and time series.. The default method, aggregate.default, uses the time series method if x is a time series, and otherwise coerces x to a data frame and calls the data frame method. aggregate.data.frame is the data frame method. If x is not a data frame, it is coerced to one, which must have a non-zero number of rows.
