Material and Equipment Considerations In Concrete Pumping

From the naturally existing water,concrete is the next widely used product.Concrete represents the foundational aspect of every building and structure thus special emphasis must be applied in the construction to ensure high quality and longevity of the building is attained.Concrete pumping equipment should therefore be selected with caution and maintained to deliver good concrete free of air and well mixed for high quality.

Functional Designs Of Concrete Pumps

Inevitably,during construction,certain areas will be inaccessible for normal delivery of the concrete mixture. Concrete pumps are specially designed to deliver this mix.Direct acting pumps are designed to deliver concrete over more than 1000 meters horizontal distance, and can rise the mix to 120 meters height.Therefore they have greater functionality and can deliver greater volumes of concrete.

Peristaltic pumps operate through a vacuum system and can cover a horizontal distance of 90 meters and an elevation of 30 meters.Pumping of concrete also reduces handling which could affect the quality of concrete.

Effect of Heat Evolution During Concrete Pumping

Heat results from cement hydration reactions and can result to cracking once the cement has set.The intensity of these reactions is determined by the amount of clinker in the cement itself.Frictional forces during pumping could also lead to heat evolution and should be minimized.

Rheology and Pumping

The flow rate of a concrete mix is a critical consideration during pumping. Construction engineers use various techniques to determine this flow rate to achieve longer lasting concrete structures. The Bingham model is one of the techniques used for determining the interparticle friction but is currently being replaced by rheometers.These equipments have proved very useful in handling of self compressing concrete.

Critical Requirements for Pumping Concrete

Critical Requirements for Pumping Concrete

Certain characteristics of concrete are important for a successful concrete pumping operation;these include.

  • The concrete mixture should neither be too dry ,nor too wet for easy movement through the system.
  • Friction is a major consideration in pumping and an adequate amount of water is required.Presence of a motar film at the walls of pipes also enhances lubrication.
  • A higher percentage of cement is beneficial for concrete pumping.
  • The size and shape of aggregate as well as presence of air in the mixture interferes with effective pumping of the mixture.Too much air could restrict pumping.

Enhancing Durability during Concrete Pumping

The transportation and delivery of concrete to the site affects their durability. Concrete pumps must always be at their highest efficiency  to avoid this delay. Durability index is a method used to determine the  stability and hardiness of a concrete structure. Air may get introduced during pumping and make the concrete unable to resist temperature fluctuations.This leads to reduced longevity of the concrete.

Conclusion

The concrete pump is a critical requirement in delivery of concrete to inaccessible sites. It helps reduce handling and delivery time of the mix which are critical in the durability of concrete.Two particular designs of concrete include the direct pumping system and the peristaltic systems.Proper proportioning of mixed concrete enhances setting,transporting and durability of the concrete.

10 Worst Results of Applying Improper Concrete Mix

How Failure Happen in Concrete Mix?

Concrete mix produces efficient results in terms of adding strength to the construction structure. Failure to meet the proper requirements in obtaining the right procedure and right ingredient in concrete making leads to formation of cracks and poor building structure with seepage possibilities. Concrete bears good tensile strength however; the same has to be preserved in terms of following appropriate mixing guide. The common mistake which many construction workers commit is that they either add excess of water or little water than the required amount. This amounts to leakage and improper curing of concrete slabs.

Improper Concrete Mix-Some Facts Behind

Improper mix results due to the following factors

  • Not managing the mix with the right quantity of water
  •  Excess of water in the mix leads to formation of humidity in between which may obviously lead to lack of curing
  • Cracks on the concrete surface may appear soon.

A transit mixer is a truck or trailer with a rotating drum which mixes and blends the concrete while on transit. The transit mixer is very much beneficial for the construction sites which require prompt delivery of freshly mixed concrete. Basically, there are two types of transit mixers, truck mounted transit mixers and trailer mounted transit mixers. When the drum in the transit mixer rotates clock wise, the concrete is being prepared and when it rotates anti clock-wise, it pours the concrete out of the drum.

Concrete Pumps

There can be many places in construction equipment where any other construction equipment cannot reach like on a high rise building or the middle of a long tunnel. In these places, if the concrete is to be poured, then a concrete pump can be of great use. Advanced constructions have become quite easier with the help of concrete pumps.

Ready Mix Concrete Plant

Ready mix concrete plant is a centralized factory or batching plant which is situated near the construction project. The concrete is mixed in the ready mix concrete plant and then transported through a truck or trailer to the construction site. This type of concrete batching plant is advantageous for the small construction projects where the requirement of concrete is in less quantity.

Compact Concrete Batching Plant

The compact concrete batching plant is used to prepare the concrete at the construction site itself. It is used in the construction site where energy saving is the major requirement. It occupies very little space and as it is located at the construction site itself, the concrete can be supplied quickly. Compact concrete batching plant is well known for easy maintenance and low running cost.
