This main objective of this research is to evaluate the variability of the mechanical properties (compressive strength, modulus of elasticity
and tensile strength) and bond strength of the self-compacting concrete (SCC), with 50 MPa compressive strength at 28 days, varying
the maximum aggregate size and the SCC fluidity. The tests were made in 15 x 30 cm concrete cylinders and in beams standardized by
Rilem-Ceb-Fib (1973). In agreement with the obtained results, can be concluded that the variability of the self-compacting concrete is
small for the modulus of elasticity and for the compressive strength, but the tensile strength presented a significant variability due to the
failure mode. About the bond strength, the variability was small showing that the self-compacting concrete is reliable and possesses great potential for use in the civil construction. |
