The Relationship of Compressive Strength and Tensile Strength of High Performance Concrete

Abstract

Fly ash and blast furnace slag dumped not only pollutes environment, but also consumes landfills. With the aim of sustainable development, the isolated contribution of fly ash and blast furnace slag in concrete to the mechanical properties of frame concrete is investigated. An experimental study is conducted to investigate mechanical properties of high performance concrete. Test variables are the replacement levels for FA series (10%, 20% and 30%) and for BS series (10%, 30%, 50% and 70%) in place of part of cement. Compressive, splitting tensile strength, modulus of elasticity and flexural strength tests were carried out to evaluate the mechanical properties for up to 7days and 28 days. The mechanical properties of high performance concrete compared with predicted values by ACI 318-02 Code, EC 2-02, JSCE Code, KCI Code and proposed Eq.
