UHPC Aggregate - Mining of Nature Corundum in Zimbabwe

After a hard day in the corundum mine, blasting, grinding and transporting, we earned a cold beer by the river. 

 

 

 

 

 

Of course, with a proper distance from the shore. Some river dwellers can really be very unpleasant. On
the way to the river we found some interesting minerals here and there.

Comparison Nature Corundum - Industrial Corundum

 

Natural corundum is an important aggregate for many of our UHPC material qualities. It is a natural material that is mined without much effort. Quite the opposite of the industrial production of corundum. There, very large areas of land are destroyed for the production and an enormous amount of energy is required for the production.

Further development of HPC and UHPC binder systems for the African continent with African raw materials

Today we are starting a new UHPC development project that is unusual for us. With our friend and business partner Gordon Viol we are going to Africa, more precisely to Zimbabwe.
Gordon Viol has a mine where he mines natural corundum. Natural corundum is a very interesting material and important aggregate for some of our UHPC concrete systems. We want to have a look at the mining of natural corundum. 

But we also want to learn about local building materials and traditional building methods. How can we integrate these local materials in our HPC and UHPC concrete systems?

What are the requirements for building materials in Africa? What cement qualities are available here? How are these materials processed? It is exciting to learn about all this. Sustainable building materials, nature building materials and the processing of these building materials are at the top of our priority list for development projects. We already have many ideas. As always, we are ready to go unconventional ways. For example, we want to combine clay and earth with our UHPC binder systems. We already know very well from desert sand that it is possible to produce high-quality concrete with it. We are looking for new materials that can be combined with our existing binder systems or with binder systems yet to be developed. These binding systems should be processable under the local environmental conditions. 

For this project we want to take three weeks on site. Afterwards, we will evaluate all findings and materials in our development laboratory near Flensburg. We will report on this development project in loose order.
