Aggregates - Theory & Concepts - Materials Aggregate Moisture
Classification, sources, and testing of aggregates for concrete and asphalt.
Open the complete lessonAggregate Moisture States
Adjust moisture parameters to observe the physical states of aggregates and calculate concrete batch water adjustments.

Wet / Damp“Pores are full and a surface water film exists. Free surface moisture will increase mix water.”
Mix Water Adjustment
Free Moisture ($MC - AC$):1.50%
Adjustment:Subtract 12.0 kg
Adj = 800 kg * (1.50 / 100)
