ACI MATERIALS JOURNAL TECHNICAL PAPER Title no. 103-M03 Evaluation of Ratio between Splitting Tensile Strength and Compressive Strength for Concretes up to 120 MPa and its Application in Strength Criterion by Nihal Arιoglu, Z. Canan Girgin, and Ergin Arιoglu A large-scale regression analysis was carried out using experi- supplementary cementitious materials (fly ash, bottom ash, mental data gathered from various sources to evaluate the ratio of silica fume), various water-cementitious material ratios (w/cm) splitting tensile strength to cylinder compressive strength as a ranging from 0.24 to 0.55, testing ages from 1 to 360 days, function of compressive strength of concrete. The reliability of the curing temperatures from 0 to 30 °C (32 to 86 °F), and proposed equation based on experimental data for compressive several moisture conditions. Concrete compressive strength strength ranging between 4 and 120 MPa (580 to 17,400 psi) was assessed by means of the integral absolute error (IAE). It is also varies from 4 MPa to approximately 120 MPa (580 to shown that, by only knowing compressive strength and the ratio of 17,400 psi). To confirm the derived relationship, test data tensile to compressive strength, the failure envelope for very high- from other sources8,14-17 were used for verification. strength concrete can be established using Johnston’s strength 2. To verify whether Johnston’s strength criterion is valid criterion without performing triaxial compression tests. A numerical for high-strength concretes by making use of the derived example demonstrates the
