- aggregation title "Conversion factors for direct and indirect tensile strength in case of self-compacting concrete".
- aggregation abstract "Over the last decades several direct and indirect measuring techniques have been developed for the determination of the tensile strength of concrete. Several conversion formulas are known for the conversion of a result obtained by a specific method (e.g. indirect tensile test) into one obtained by another method (direct tensile test). Recently, it was shown that the compressive strength conversion factors for CVC are not entirely valid for SCC. Similarly, this may also be the case for the existing tensile strength conversion factors. The goal of this study is to investigate if the current conversion factors (size, shape and test method factors), which are used for transforming conventional vibrated concrete (CVC) tensile strengths, are valid for use with self-compacting concrete (SCC) tensile strengths. Here for, an experimental program was run on four different powder-type SCC mixtures. Firstly, the size and shape effects were investigated. For the splitting test, no valid existing size factor expressions were found. For the bending test, it is shown that the current design codes (Eurocode 2 or Model Code 90) can be used to make a rough estimation of the size factors for SCC. For the splitting test shape effect, no significant difference was found between CVC and SCC. Secondly, for the relationships between different tensile strength test methods, it was shown that a slight overestimation of the conversion factors is obtained using the model proposed in EC2. Other expressions, found in literature, showed better correlation with the test results. Finally, for the relationship between the tensile and compressive strength, it was found that the design codes (EC2 or MC90) provide a safe and realistic approach to estimate the tensile strength from the compressive strength of SCC.".
