Why Pump Concrete? 

The basic advantages of pumping concrete are; continuous pour, speed, increased site flexibility, and most important is a stronger wall!

 Concrete that is delivered to a project is generally between 4-6 slump inches. It should contain enough mix water to produce a workable mix, which is placeable and does not segregate.  Placement of the concrete with a pump truck does not require additional water.

 Adding an excessive amount of water:

q       Will reduce the durability and strength of the concrete.

q       Will increase the cracking potential of the concrete due to shrinkage!

 What are the potential results of adding additional water?

If only one gallon of water is added to a yard of 3000 PSI concrete mix:

·        The slump is increased about one inch.

·        The compressive strength is reduced by as much as 200 psi.

·        The effect of about ¼ bag of cement is lost.

·        The shrinkage potential (cracking) is increased.

·        The possibility of moisture penetrating through the concrete is increased.

·        The freeze-thaw resistance is reduced – scaling is increased.
