recommended sampling and testing frequencies for process control available to the Producer. A process control plan should include procedures for all aggregates produced to determine grading, plasticity index, deleterious substance content, and other properties that may be required by the specification, and to

reactivity of aggregates are known to vary from source to source, it may be necessary to implement a rigorous testing regime to establish aggregate reactivity and evaluate preventive measures. In the

Moisture Measurement in Aggregates and Sand Hydronix sensors were originally designed for the readymix and precast concrete industries to increase the accuracy of batching and slump control. However, microwave moisture measurement has also proved to be invaluable in other industries that use sand or aggregates during processing.

In light of the UMWA's objection to drug testing, it may come as no surprise to mine operators in the aggregates sector that there is no regulation for coal mines restricting or prohibiting the use of alcohol or drugs on coal mine sites. Metal/nonmetal mines have a single regulation addressing drug use at a mine site (30 §§ 56/):

The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material, aggregate, and water. Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete.
