High Performance Concrete, i.e., those whose compressive
strength is higher than 40 Mpa, have been used in a wide
range of Civil Engineering applications. Notwithstanding
that, it is known that their mechanical and physical
properties are different from those of their conventional
counterparts. In this dissertation, it is studied mixture
proportion methods with good acceptance rate, preparing 230
specimens with materials available in Brazil`s state of
Rio de Janeiro and that have compressive strength of 40
MPa, 60MPa, 80 MPa and 100 MPa. For each prepared specimen,
it is studied its mechanical properties, compressive
strength, splitting tensile strength, modulus of elasticity
and porosity for the determination of the emptiness ratio.
It is also studied the compatibility between
superplasticizer and cement materials. It is also performed
a comparison between the experimental data and the
expressions available in the literature, as well as the
relation between the compressive strength, splitting
tensile strength, modulus of elasticity and the porosity.
