Splitting tensile strength of self-consolidating concrete containing slag

Abstract

The use of supplementary cementitious materials (SCM) as partial replacement of ordinary Portland cement is widely accepted in the construction industry. The adverse environmental impact of producing cement is mitigated through the reduced production of cement due to the use of SCM. In addition, SCM such as fly ash, silica fume, and slag, impart many favorable fresh and hardened concrete properties. The present study assess the splitting tensile strength of sustainable self- consolidating concrete in which up to 80% of the cement was partially replaced with ground granulated blast furnace slag (GGBS). A total of eight mixes were produced by varying the percentage of GGBS used to replace cement content in high strength concrete mixture. The fresh properties were assessed through the flow test, visual stability index (VSI), and the T50. The compressive and splitting tensile strength were also determine. Relationship between splitting tensile strength and compressive strength was proposed and compared to various design codes.
