PLACEMENT

SEE ALSO READY MIX TRUCKS PUMPING VIBRATION

Placing the Concrete where it needs to be. The goal is to ensure it is delivered evenly, consistently, and maintained in a workable state throughout the operation to avoid defects such as air pockets, segregation, or cold joints.

A major focus in modern concrete placement lies in the selection of appropriate Pumping and Delivery methods. Pumping is one of the most efficient and commonly used techniques, especially in high-rise buildings or areas with limited access. Concrete Pumps—whether Line Pumps for horizontal distances or Boom Pumps for vertical reach—allow for fast, consistent delivery of concrete with minimal handling, reducing the risk of segregation and delays. 

Delivery Trucks or Transit Mixers also play a key role by transporting ready-mix concrete from the batching plant to the job site, preserving mix consistency. Once on-site, concrete may be discharged directly or transferred via chutes, buckets, or conveyors, depending on project demands.

Challenges often arise from environmental factors such as heat, rain, or freezing temperatures, which can affect the workability and setting time. Additionally, improper delivery methods or dropping Concrete from excessive heights can cause material separation, compromising structural integrity. Using Vibrators is essential to eliminate air voids. The Placement process must be timed carefully to prevent Cold Joints, which occur when concrete layers are placed too far apart in time.
