Moisture Control in Concrete Production Agg-Net

Although this article concentrates on slump, surplus water or moisture content in the sand and aggregates can also have dramatic effects on the water/cement ratio, the aggregate/cement ratio, the yield and the colour of the mix. This will lead to inconsistencies in slump, strength, colour and quality, resulting in an inferior end product. Why is the correct moisture calculation important? If ...

Moisture content in stored sand and aggregates can have dramatic effects on the water/cement ratio, the aggregate/cement ratio, yield and the colour of the mix. Measuring the moisture content of the raw materials can enable the plant controller to adjust water addition into the mix in real time, minimising these effects. This enables batch after batch of concrete to be produced to the same ...

DETERMINATION OF MOISTURE CONTENT

Limits of the method: measures do not give moisture content of the product directly. Calibration charts must be established based on desorption and sorption studies. Relations are rather complex and use either mc on a wet or dry basis.
