The proper mix design can be readily achieved without sacrificing desired properties. The water cement ratio can be maintained by using a high range water reducing agent in order to achieve the desired pumpability (I.e. slump). Proper selection of aggregate and sand is also important for good performance when using a pump. A reputable ready mix concrete supplier can provide mix designs that have been successful used in the past.

Hi all,
Pumping concrete to high rise structures require wetter mix that may result even up-to 7" slump. Is increasing in slump results
aggregate segregation that might cause serious loss of strength in concrete?
