PUMPABLE CONCRETE

Is ‘the pumpable concrete mix’ representing a seperate concrete class?

If you pump the concrete, the right recipe is always the most economical solution. This is important because approximately ten billion m3 of concrete are produced in a year all over the world. And most of them are conveyed with the concrete pumps. That means in many situations, concrete is placed through pipes.

Although the pumpability of the concrete is the primary condition, the losses during conveying and placing i.e. pumping must also be taken into consideration. Additives are widely used today, however it is not possible to make up for every defect in concrete with additives.

Nowadays in many situations, concrete is placed through pipes ie by pumps. Thus the engineers and all other people in-charge must be acquainted with the pumpable concrete.

Today, many plants are preparing concrete mixes with computer aid. Therefore, the right recipes for different concrete mixtures to be pumped can be prepared easily and without errors.

Does the proporties of the concrete not change while pumping?
Does an old, bad or incorrectly selected pump damage the concrete properties?
How can fast pumping damage the concrete?
Water or sand which is better to facilitate pumping?
How do you prepare a pumpable mix?
What grades of concrete can be pumped?
How does concrete move in the pipeline?
How do the pump hopper and valve structure and pipes affect concrete proporties at the end of hose?
Wouldn’t it be better and more realistic if the samples are taken from the hose end instead of mixer?

All answers of these questions are in this e-book which consists of following sections. What is concrete, concrete components, fresh and hardened concrete properties, gradation curve, concrete mixtures, design of pump concrete, willingness to pump, concrete in the pump, concrete in the pipeline, concrete pumping mechanics, pumping applications.
