Moisture Measurement for aggregates and sand using Hydronix ...
Modern plants can weigh aggregates with an accuracy of up to ± 0.5%. If the amount of moisture in a batch of sand or aggregates varies from between 2% to 10% then this will affect the accuracy and proportions of the weighed materials since water is effectively being weighed and not dry materials.Learn More
Determining Moisture in Aggregate for Mix Proportioning ...
Sand can be expected to contribute about 2 to 6 percent free moisture by weight, and gravel or stone about 1 or 2 percent. Under average conditions that means that 104 pounds of sand would give you the equivalent of 100 pounds of sand in what is called a saturated surface dry (SSD) condition and 4 pounds (1/2 gallon) of free moisture.Learn More
