Batching Dry Aggregates in Concrete Concrete Construction ...

A.: For normal-weight concrete, batching dry aggregates shouldn't cause any problems. Most air-dry aggregates don't absorb more water than a percent or so by weight of the aggregate. The batch plant operator can correct for the amount of water absorbed by adding more water at the plant. Batching very dry lightweight aggregates can cause ...

Methods of Batching Concrete - The Constructor

To make 1:1:2 ratio concrete mix according to volume batching, one should take one bag of cement (35 liters) , 1 gauge box of fine aggregate (35 liters) and 2 gauge boxes of fine aggregate (70 liters). If the water-cement ratio is 0.5, then half of the volume of cement which is 25 liters of water should be taken. Fig 1: Gauge Box or Measuring Box.
