Due to the advances in the scientific and technological knowledge of concrete several special concretes have been developed. High Performance Concrete (HPC) is one of the most important. It is used for a wide range of field applications as it shows high early strength, low porosity and good durability. HPC has been applied in the construction of many important structures and has been specified where only service life is required. This paper presents test results obtained from drilled cores obtained from 2 years old slabs of 2.00 by 4.00 by .20 m with the purpose of analyzing the physical mechanical properties in field conditions. A conventional concrete and three High-Performance Concretes were evaluated. Compressive and tensile strength, permeability, resistance to abrasion and absorption were measured. The effects of improper consolidation and the introduction of mineral admixtures (a natural pozzolan was incorporated) are discussed.
