The influence of three coarse-aggregate types on the relationships between compressive and tensile (split tensile and modulus of rupture) strengths of a plain concrete was investigated. It was found that, in some cases, aggregate type has significant effects on these strength relationships. The mineralogical differences in the aggregate types are considered to be responsible for this behavior. The commonly accepted 0.5 power relationship between compressive strength and tensile strength was found to be applicable neither for all aggregate types nor at different ages. From the available experimental data for modulus of rupture and splitting tensile strengths of concrete, alternative relationships between the tensile and compressive strengths were calibrated and are presented. Finally, a previous study of the effect of three coarse aggregates on the coefficient of linear thermal expansion and water-cement ratio was discussed and enhanced using graphic representations of the relationships. The correlation between the experimental results and analytical predictions provides a simple approach for developing tensile strength models for plain concrete using three types of aggregate. Tables of results and figures supporting these observations and conclusions are included.
