The formulation of high-performance concretes is deduced from that of ordinary concretes which are a mixture in the appropriate proportions of binder, aggregates, water and optionally, admixtures. These types of concrete composed of ultrafine materials, including metakaolin in the case of this study, are characterized by high mechanical resistance and good workability due to the addition of a water-reducing superplasticizer. However, for a successful formulation, materials must be carefully studied to ensure their use. This research project aims to characterize all the materials used in the composition of high-performance concrete to serve as a reference in other similar work in Chad. These are the physical, chemical and mechanical characteristics of materials including cement, gravel, sand, superplasticizer and metakaolin, coming from various locations in Chad. After analysis, the characteristics of these materials are satisfactory and comply with international standards and hence favorable for the composition of high-performance and sustainable concretes.

Abstract
The formulation of high-performance concretes is deduced from that of ordinary concretes which are a mixture in the appropriate proportions of binder, aggregates, water and optionally, admixtures. These types of concrete composed of ultrafine materials, including metakaolin in the case of this study, are characterized by high mechanical resistance and good workability due to the addition of a water-reducing superplasticizer. However, for a successful formulation, materials must be carefully studied to ensure their use. This research project aims to characterize all the materials used in the composition of high-performance concrete to serve as a reference in other similar work in Chad. These are the physical, chemical and mechanical characteristics of materials including cement, gravel, sand, superplasticizer and metakaolin, coming from various locations in Chad. After analysis, the characteristics of these materials are satisfactory and comply with international standards and hence favorable for the composition of high-performance and sustainable concretes.
