Objective
It is anticipated that the need for high performance concrete, in building and civil engineering, will highly increase in Europe. But now, the construction references relate only to a few particular and large projects. Therefore, the production on an industrial scale of high strength concrete is very important for the competitiveness of small and medium size contractors involved in building and civil engineering works in Europe.
The two main industrial objectives of this project are:
1. To reach a high strength concrete (up to 80-120 MPa*) using a new and cheap ultrafine mineral admixture blended with various aggregates and cements,
2. To define the working up process in order to produce on any construction site in Europe (areas difficult of access and small sites in particular) a cost effective high performance concrete.
The three principal objectives of the project were successfully achieved during the contract period. More specifically, it was concluded that:
1. The diatomites can be adequately characterised and treated for ensuring their selection as ultrafine admixtures in high performance concrete,
2. With further industrial developments it could be possible to market diatomites at a lower cost than conventional mineral admixtures and especially silica fume,
3. High performance concretes (about 90 MPa) can be produced with diatomite in optimised compositions that benefit from the positive effects and compensate any negative effect of the diatomite incorporation,
4. The behaviour of the resulting concretes is comparable to conventional high strength concretes,
5. Dry mixes of diatomite concretes are technically and economically feasible.
The project working program aims to:
-identify material deposits (which can be found almost anywhere in Europe) and characterize the mineral admixture properties,
-optimise the grinding process,
-analyze diatomite compatibility with various aggregates and cements,
-optimise the concrete proportioning and accurately monitor the test results,
-specify new mixing practices (including preparation and handling of concrete components),
-run some in situ trials or production batches.
