The present paper gives brief account of current cement production, expectation of growth in cement demand,due to various initiatives taken by the present Government in India.Variability in chemical composition of the available secondary cemeutitious materials (SCMs) is one of the critical factors limiting the further use of locally-generated SCMs in India.Author of this paper has suggested the establishment of a system matching by-products with the correct level of reactivity and appropriate mineralogy and chemistry to the most suitable end-use applications.Alternatively, the reactivity of the materials can be altered as required, for example by fine grinding.Producers and potential users need to work together to engender trust and to allow higher use of SCMs.Author has suggested for "performance-based codes" for cement and concrete instead of "prescriptive" codes,which allow higher use of fly ash, or, (1) to revise the IS code no.1489 (Part 1) for higher fly ash addition in line with specifications of different countries for blended cement, (2) the introduction of standards for making composite cement with higher SCM levels.It is necessary to reinforce the confidence level of consumers in India that higher usage of SCMs in cement and concrete can lead to higher durability and longer service-in-life and they should not think (higher additions) that it is a economically disadvantage as it will cause delay in removing formwork but it is a myth because they (consumers) would not think about the life cycle cost of the structure.
