Modulus of elasticity of blended concrete containing multiple admixtures for sustainability infrastructural material

摘要

The strength and modulus of elasticity (E) of concrete are an important aspect for design. Hence, to achieve this parameter use of industrial and agricultural byproduct can be used in concrete as partial replacement of cement. For such new triple blend concrete is needed to determine the compressive strength and ultrasonic pulse velocity (UPV), modulus of elasticity (E) and microstructure of concrete. To this objective, various mixtures of concrete were produced by replacing 20%, 30% and 40% of cement with FA and RHA blends. The modulus of elasticity was determined by various formulations such as UPV, IS and ACI. The modulus of elasticity, compressive strength and durability of triple blend concrete were improved at 20% cement replacement. As a results the concrete makes sustainable with this new triple blend.
