Abstract
Production of durable concrete at lower strength levels is always a challenge for concrete technologists. One way to achieve this objective is by the use of Supplementary Cementitious Materials (SCMs). An attempt has been made in this paper to develop indicators called performance indicators, which combine both strength and durability criteria. Limiting values of these indicators are also suggested. Different mixes in the same strength range are classified into different performance classes based on these performance indicators. The durability parameters evaluated here include surface resistivity, charge passed, sorptivity index and oxygen permeability index. The database generated can act as a guideline for material selection and it demonstrates the potential of SCMs to improve durability.
