Future Directions in the Cement Industry

The paper views the cement industry holistically: cement production tied to construction and that, in turn, is tied to investment.As alternatives to concrete exist in many applications, infrastructure investment does not automatically result in more concrete being made. The paper recognizes that existing tests and standards are inadequate tools with which to enhance the performance of cement concrete in a wide range of service environments. Existing performance related tests rest on an empirical foundation and often fail to control important variables or accord with relevant physico-chemical considerations. The emerging new methodology for predicting durability uses chemical-mineralogical-kinetic models that are essentially solved using computer based iterations. Not all necessary data with which to implement the models is available as yet, but rapid progress means that almost the entire body of existing standards for specification and testing the durability of concrete is obsolete.Predictive modeling needs to be supported, extended, completed and verified now. so that a fully flexible and comprehensive tool will be devised with which to tailor concrete specifications for optimum performance and meaningful service life predictions.
