The free moisture must be accounted for when batching our concrete to help control mix costs and to improve its quality and consistency. Free Moisture. Consider the amount of water in 1,854 pounds of sand (which is a typical amount of sand for a yard of pipe machine concrete) that has 4% total moisture in it and has an absorption of 1%.

Placing Concrete Topic
To provide durable concrete, it should be free of segregation and the mortar should be in close contact with the coarse aggregate, reinforcement, and any adjacent faces to which it is to be bonded. Concrete should be deposited, as nearly as practicable, in its final position. Placement of concrete is accomplished with buckets, hoppers, manual …
