The oven-dry test, combined with the prong or stress test, is a very useful tool for the kiln operator to have at his or her disposal. Often the kiln operator is asked to defend the accuracy of moisture meter measurements or a customer simply does not believe moisture meter readings. In other situations, the operator may want to verify

Absorption capacity, or absorption, represents the maximum amount of water an aggregate can absorb. It can be determined by finding the weight of an aggregate under both SSD conditions and oven-dry conditions. The difference in weights expressed as a percentage of the oven-dry sample weight is the absorption capacity. Coarse aggregates are .

100 lb of loose gravel can fill a 1-cubic foot box. What is the dry rodded weight? Note: Unit weight or bulk density (B) [also called dry-rodded weight, specific weight and dry-loose weight) is the mass (weight) of many particles of the material divided by the total volume they occupy.
