Abstract:This paper aims to contribute to decisions concerning the use of fine materials, responsible for the segregation resistance of self-compacting concrete (SCC). In this study, samples of SCC were prepared with fly ash, a pozzolanic waste ,and fine sand that is a non-pozzolanic material, using the dosage method proposed by Tutikian-Dal Molin (2007) . It was observed that the utilization of fly ash increased the resistance to compressive strength, mainly in more advanced ages, as well as the values of the elastic modulus and the propagation speed of ultra-sound waves. It has also decreased the penetration of chloride ions to the same strength values, where it was also observed that the final cost of the fly ash SCC was lower than the fine sand SCC for similar strength levels. Both dosage and performance diagrams were shown.
