Most or all water will likely be batched for the plant. The mixer drum is turned at charging (quickly) velocity through the loading of the resources. You'll find 3 options for truck combined concrete:
Aggregates- Sand would be the fantastic combination. Gravel or crushed stone would be the coarse combination in many mixes.
