Evaluation and comparison of the analytical models to determine tensile strength of self-compacting concrete and conventional concrete

Differences in mixture proportions and applied materials between self-compacting concrete (SCC) and conventional concrete (CC) can result in an essentially effect on the physical properties and on the mechanical properties. Therefore, it is important to investigate that whether all of the assumed hypotheses for CC to design the structures are also valid for SCC construction. The tensile strength (TS) of concrete is important to predict the initiation of cracking of concrete members when it is subjected to external loads or by shrinkage alone. For design considerations, the shear, punching, anchorage, crack control, and minimum reinforcement directly depend on the tensile strength of the concrete. Relation between tensile and compressive strength of concrete changes by various factors including, the aggregate type and particle size distribution, age of the concrete, curing process and air content. This paper reviews the accuracy of the six models for SCC and nineteen models for CC for determining the TS of concrete. The predicted results are compared with the actual measured TS of concrete from the previously conducted experimental results in 86 mixtures of SCC and 26 mixtures of CC.
