Splitting tensile strength of sustainable self-consolidating concrete

Abstract

Construction industry is known to be a contributor to environmental pollution in various ways including the production of cement. It is common nowadays to produce concrete in which cement is partially replaced with sustainable minerals that impart favourable properties on the concrete mix, such as fly ash, ground granulated blast furnace slag (GGBS), and silica fume. The properties of high-replacement concrete mixes are still being studied. One of the concrete properties of interest to the designer is the splitting tensile strength of concrete. In this study, sustainable self-consolidating concrete (SCC) mixes were produced in which 80% of the cement was partially replaced with various combinations of minerals. Relationships were developed between the splitting tensile strength and the 28-day compressive strength for the control concrete mix as well as the mixes in which cement was partially replaced with mineral admixtures. The relationships developed in this study were compared to those proposed in selected concrete codes such as ACI 318.
