Rebound index and ultrasonic pulse velocity measurements were made in 9 columns designed with P-35 ordinary Portland cement mix. Eight models were compared, of which those proposed by RILEM and Tanigawa et al. showed an error of less than 4% with respect to the reference value, determined by breaking of concrete cylinders. The results obtained demonstrate the feasibility of using the models to estimate the compressive strength of concrete, using national materials.]]></p></abstract>

As medições do índice esclerométrico e da velocidade de pulso ultrassônico foram feitas em 9 colunas projetadas com mistura de cimento Portland comum P-35. Oito modelos foram comparados, sendo os propostos por RILEM e Tanigawa et al. apresentou um erro inferior a 4% em relação ao valor de referência, determinado pela quebra do corpo de prova. Os resultados obtidos demonstram a viabilidade de utilização dos modelos para estimar a resistência à compressão do concreto, utilizando materiais nacionais.]]></p></abstract>
