how to measure sand in batching plant industry

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 ...

Volume Batching. 1:2:4 generally represents the ratio for M15 concrete. It is generally done by volume batching not by weight. After adding water to the dry mix, the gross volume of concrete reduces from the sum of individual volume of cement, aggregate and sand.
