What is it about?
This paper describes the relationship between splitting tensile strength and compressive strength of self-consolidating concrete using data collected from laboratory specimens tested at standard conditions. The specimens contained either nano or micro size silica added as a cement replacement. The investigated variables included: type of cement, percentage of nano-silica and percentage of micro-silica as a cement replacement by weight.

Why is it important?
In spite of concrete not being designed to resist direct tension the knowledge of tensile strength is needed to estimate the cracking load. In the absence of test results an estimate of the tensile strength may be obtained by using the relationship proposed.
Perspectives
The output of this study has provided a better understanding of the correlation between splitting and compressive strengths of SCCs and the effect of some related variables on the resultant behavior, which has therefore, helped to generate new expression with better accuracy.
