Soil Aggregates

Soil aggregates as noted in the section on soil structure in Chapter 1 play a central role in protecting pools of carbon and nitrogen and are derived from a variety of sources A mechanism particularly prevalent in many tropical soils is the physical aggregation process which occurs abiotically as a physicochemical process (Oades and Waters 1991) get price

Crushed Concrete Aggregate

Jun 30 2011Thus CCA—combined with the fine aggregate or "dust" from the crushing process—has a higher demand for water and cement resulting in the potiental forgreater shrinkage and lower strength Because the crushing process produces concrete aggregate with jagged edges and dust the resulting concrete was considered too harsh for applications get price
