Probabilistic conversion of the compressive strength of cubes to cylinders of natural and recycled aggregate concrete specimens
This research was funded by the EcoCoRe doctoral program through the Portuguese Foundation for Science and Technology (FCT)-Fundacao para a Ciencia e a Tecnologia, grant number PD/BD/113643/2015. ; This paper investigates the effect of recycled coarse aggregate incorporation on the relationship between 150 mm cubic and Φ 150 mm cylindrical compressive strength (the reference strength of standards) by comparing data from recycled and natural aggregate concrete compositions in which both cubes and cylinders were tested. A conversion factor from cubic to cylindrical strength is proposed in two versions: A deterministic and a probabilistic one. Such factor has not been studied before and researchers have been converting cubic data as if natural aggregate concrete were tested. The probabilistic factor is intended for reliability analyses on the structural behaviour of recycled aggregate concrete using data from laboratory cube tests. It was found that the incorporation of recycled coarse aggregates sourced from concrete waste significantly decreases the expected value of the factor but the factor's scatter is relatively unaffected. ; publishersversion ; published
