Macroaggregate

Larger aggregates and sandsized particles contain organic matter that is younger, less aromatic, more aliphatic, and/or more polar than material associated with smaller aggregates. Macroaggregates are far more susceptible to disruption by cultivation and environmental perturbation (, wetdry cycles) than are microaggregates (Tisdall and Oades, 1982). For example, organic matter lost from ...

Wet Sieving: A Practical Guide

Wet sieving is usually performed with one of two purposes in mind. Either the operation is performed to determine a fraction retained on a sieve or sieves, or it is a method of sample preparation that allows a later particle size analysis to be performed more easily or accurately. The procedures are often similar, but the one you choose should be based on your end goal.

Wet Belt Concrete Aggregate Cooling

Aggregate cooling is a type of cooling system that cools aggregates in concrete mixture. There are different types of aggregate cooling. One common method is the wet belt system. This method is so popular because it is a costeffective alternative to sand cooling and other higher costs methods. Using the wet belts allows the concrete to travel along a conveyor belt while being chilled by water ...
