[automatically translated] The concrete "with high mechanical performance" are generally associated with production technologies and installation complex work; often tries to justify thereby executive and performance deficiencies, also works to which you require resistance values that now can be regarded as ordinary; the rest of the definition of "high strength" conglomerate is closely linked at the time of production. The experimentation exposed in this publication defines the composition of a mixture that reaches a compressive strength as high as possible, using for its packaging a common cement mixer and by appropriately selecting the materials to be used. Were used CEM I 52.5 R, silica fume, silica sand, granite aggregates (sand and coarse aggregate) and an admixture based on polycarboxylate ethers; It was packed with medium strength concrete compressive after twenty-eight days of 101.5 N / mm2. The purpose of the research is to demonstrate how even a "complex" requirement which the high compressive strength can be satisfied even with the most common equipment if enforcement was marked by the principle of quality.
