Ready-mix concrete a saving strategy for construction companies in East-Africa

Ready-mix concrete refers to concrete that is manufactured in a batch plant in accordance to set engineered mix design.

The use of ready-mix Concrete from batching plants in Africa is fast-gaining popularity as evidenced by the increase in the use of ready-mix concrete supplied to engineering & construction sites. The need for controlling expenditure (cost), increase delivery times as well as the need for consistency of each concrete batch are just some of the factors that have driven demand. The growth in the concrete batching plant market in Africa has been driven primarily by large infrastructural projects, in addition to a growing use of medium sized batching plants in building projects as the need for housing takes center-stage across Africa.


Controlling concrete delivery on many construction sites in East Africa can be especially difficult. Construction sites are more likely to be in remote areas, and warm climates can mean an extra strain on delivery times. Ready-Mix Concrete Batching plants can today be seen dotting virtually all large infrastructure projects.

Premix Supply Concrete companies like “IBM ReadyMix Concrete Ltd Uganda”  have been setup around East Africa exclusively to providing ready-mix concrete to meet the demand from a growing number of construction projects in urban areas. According to Eng. Mathew Kasujja of IBM ReadyMix Concrete Ltd Uganda, contractors have come to the realization that costs can be reduced by outsourcing this function and simply ordering ready-mix concrete rather than going the more traditional labor intensive way of concrete production onsite.

This trend towards outsourcing has been driven by several benefits which can-not be under-estimated as profit margins in development projects have become leaner. According to Martin-Ssonko, Operations Manager at IBM ReadyMix Concrete Ltd Uganda, the best option is to use mobile concrete batching plants. He adds that erecting a mobile batching plant near the construction site will provide the opportunity to get the desired concrete at desired amount, quality and time. It’s evident that the construction industry is trending towards the use of batching plants to supply ready-mix concrete to sites as greater awareness of the benefits becomes more appreciated.

According to Eng. Mathew Kasujja,the major reasons that we constantly read about buildings collapsing while under construction is due to poor concrete mixes. This is all too prevalent when you consider the number of reported collapses of projects in the daily papers. One of the main culprits has been failure to allow the concrete enough time to cure,  human error on the part of the contractor mixing the concrete on site to the more devious practice of cutting back on the required quantities in the mix by an unscrupulous contractor. For the developer it means costly remedial action and even prosecution in court for negligence especially if there is injury or fatalities involved.

Technological advancements in Africa have seen modern plants having internet connections whereby calibrations can be done online; also human interface automation which makes it easy for the operator to control the plant and ensure quality concrete production as witnessed at iBM ReadyMix Concrete Batching Plant.The automation systems go as far as, power panel and switches, batching control terminals, automatic control unit, software, control panel, computer, screen and plotter.

 Land Issues

As the value of land grows so has the final cost of a development project and in order to remain viable it has meant that a developer needs to utilize every square inch of land on a project efficiently. This has meant that there is no luxury to provide space on site for trucking in sand, aggregate and stocking cement for laborers to mix concrete.

The more attractive alternative has become ordering concrete which is delivered to the site on mobile concrete mixers that drive in, and pump the concrete into the required location an activity that is competed in a matter of hours so that sites can remain relatively clutter free.

Security of Material

In a traditional site, pilferage is always a reality. Theft of cement, delivery of less-supplies of sand and aggregate by unscrupulous truckers occurs more often that is realized.To provide a more reliable concrete mix the use of supplies provided by a batching plant means greater consistency in the mix throughout at a predetermined fixed cost. It also helps do away with pilferage that is all too rampant when you have cement bags stored on site.

According to iBM ReadyMix Concrete Company Uganda engineers, there is virtually no wastage when it comes to the supply of read-mix concrete. Mixing concrete on site results in a high level of wastage of material where it is as a result of torn bags of cement or aggregate and sand split haphazardly during delivery. This is something that is the bane of any developer who has to foot the cost of such wastage. Concrete produced in a batching plant ensures no wastage and the client only pays for what he ordered.

Meeting exact specification:

According to Mr. Ssonko the Quality Assurance Manager at iBM ReadyMix Company Uganda, testing of the concrete at the batching plant ensures that what is delivered to site is of consistent quality and according to specifications whether it involves concrete with a faster curing time or waterproofing characteristics. Any requirement can be met reliably and consistently for the contractor to ensure that the project is not affected negatively by poor concrete mixes.


Concrete batching plants that supply ready-mix concrete to sites have meant that there is less pollution of  the environment with respect to noise produced by rumbling concrete mixers and the sites are relatively neater having eliminated bags of cement and heaps of sand and aggregate lying around the site.

Selecting a ReadyMix Supplier

Selecting the right ready-mix supplier and batching-plant can have a major impact in the overall success of a construction project. Therefore, before choosing a particular batching plant, Eng. Kasujja from Ibm ReadyMix Concrete Company Uganda (East Africa) advises that, the construction companies should be aware of the output of the batching-plant and if machinesare in line with what they want to produce. Price should not be the most important thing. The quality of the concrete-mix should always come first, adds Eng. Kasujja.

Setting up a Concrete Batching Plant

According to a senior engineer at Ibm ReadyMix Concrete Company Uganda (East Africa), setting-up of a batching plant requires various activities to take part. Among others include; having a main plant structure, concrete mixer, cement silos screw conveyor, belt conveyor, weighing system, dust removing system, and a control room.

Having a main plant entails construction of a batching plant foundation whereby the installation of the concrete batch plant is assembled in line with the drawing requirements as per the clients request and the construction works cooperate with each other in the installation process.

Eng Martin adds that the concrete mixer installation takes into consideration of ancillary projects like power, water rainproof measures and transport corridors of the materials sites to meet the mix requirements to reduce later alteration. Cement silo, through a crane then is hoisted vertically to the foot of the silo foundation to put it in place after which the crane is gradually loosened until it reaches the flat surface of the embedded part.

Installation of screw conveyor follows suit whereby the entrance part of the screw conveyor nears the end of the monitor, fixing the conveyor preliminary according to the import and export position to keep the interface tube in a vertical position.Nevertheless, according to Simon of iBM READY-MIX Co. Uganda from Sweden, it is paramount that you have a professional on-site to ensure that everything is in good place to avoid down-time during the project.

  1. My kids love playing basketball and I am thinking about putting a concrete court in our backyard, so I appreciate this important information about ready mix concrete. It is good to know that this type of concrete requires less human labor and the materials will increase service life. This shows me that the ready mix could save us time and money when installing the court.
