WHY IS IT SO IMPORTANT TO MEASURE MOISTURE IN AGGREGATES ?

The varying moisture contained on aggregates is one of the major causes of inconsistency in batching concrete from one batch to another. Moisture content can have dramatic effect on the concrete compressive STRENGHT and DURABILITY because it has a great influence on the WATER/CEMENT ratio. Knowing the moisture content on SAND and GRAVEL, it allows the Concrete Batch Controller to accurately calculate and adjust the amount of water to be added to the mix.
