The Correlation Between Splitting Tensile Strength and Flexural strength of Self Consolidating Concrete

Abstract

Sustainable self-consolidating concrete (SCC) is gaining popularity due to its contribution to reducing the environmental footprint of the construction industry. Sustainability of this type of concrete comes from the significant reduction in usage of ordinary cement and its replacement with reused minerals and industrial by-products such as fly ash, ground granulated blast furnace slag (GGBS), and silica fume. In this study, the correlation between the splitting tensile strength and flexural strength is investigated by studying published data in the literature. Splitting tensile strength is determined through a simple test and flexural strength is obtained from flexural beam test. A correlation between the two measures of tensile capacity is essential to determine the flexural design strength knowing the splitting tensile strength, especially for SCC. A correlation is proposed in this paper to relate flexural and splitting tensile strengths for concrete in which cement was replaced by sustainable minerals and industrial by-products.
