ᐅ Concrete Construction in Kenya

stobi_deHello,
I am asking here on behalf of a safari camp owner in Kenya and hope to find an answer.
When building a house in Kenya, it is already a relief if even a foundation is laid. Often, it is thin, made of poor-quality concrete, and without any steel reinforcement.
My acquaintance can teach the workers there how to mix concrete properly so that it does not crumble as it sets, but the problem is these steel meshes, which are hardly available in remote areas or are extremely expensive.
Anyone who has been to Africa knows the preference for paved paths there. I have never seen one that wasn’t cracked multiple times every meter.
Does anyone here know of an alternative to these steel reinforcements in concrete, a special concrete mix, or any additive that can increase flexibility somewhat?
Regards
Frank

Here in Germany, I’m usually not a fan of this, but for your purposes, try this:
To improve tensile strength, conventional concrete components typically include steel mesh or reinforcing bars. This method is time-consuming because the reinforcement must be precisely fitted and secured within the formwork before pouring the concrete. In steel fiber reinforced concrete, the steel fibers perform the role of reinforcement.
This technique offers particular advantages when casting basement walls, foundations, foundation slabs, basement floors, and industrial or warehouse floors.
The steel fibers are mixed in precisely measured quantities directly into the fresh concrete. The steel fiber reinforced concrete is then poured directly into the formwork or onto the prepared base. There is no difference in compaction and surface finishing compared to conventional methods. As the concrete hardens, the steel fibers become firmly embedded in the concrete matrix, thereby increasing the strength of the component.
Steel fiber reinforced concrete can be pumped. Structural verification can be done in cooperation with the structural engineer or architect. Using steel fiber reinforced concrete saves time and costs and significantly contributes to the efficiency of construction processes.
