In recent years, appeared very high performance concretes which are the result of a more and more scientific rationalization. The use of superplasticizers, and more recently of ultrafine particles such as silica fume, has significantly minimized the amount of mixing water in concrete while improving workability. Owing to this water reduction (and thus the w/c ratio), the mechanical strength of such concretes has considerably increased. The compressive strength may exceed 80 MPa. Therefore, their use is very promising from an economic point of view and quality of civil engineering and hydraulics works. The aim of this study is to formulate a VHPC using local materials. The design approach used is the grout method. The obtained results show a clear improvement in the mechanical performance of concrete, resulting in a sufficient compressive strength to allow formwork removal at 24 h, an acceptable tensile strength and shrinkage lower than that obtained in conventional concrete.
