How to measure aggregate moisture in a concrete mixing plant?
There is a 3 m 3 concrete batch, containing 6,000 kg aggregates with an aggregate moisture of 4%, which results in 240 kg water brought in by the aggregates. Given that the deviation of the aggregate moisture measuring is +-1%, the variation of the aggregate water content is plus or minus 60 kg.
Moisture Measurement in Concrete Mixing including Ready Mix ...
This enables batch after batch of concrete to be produced to the same, consistent quality. The installation of moisture measurement sensors into the manufacturing process provides the producer with an on-line system that operates in real time and enables the accurate control of the water/cement or aggregate/cement ratios.
