The Canadian Standard CSA CAN3-A5.M83 allows the addition of up to 5% carbonate additions for Type 10, normal Portland cement, and this allowance has recently been extended to Type 30, high-early strength cement. The possibility of extending the carbonate additions to the other cement types, including those for sulfate resistance and moderate heat of hydration, has been discussed by the A5 Committee, and some concrete test data have been presented. However, the initial results did not include testing for the effects on sulfate resisting or heat of hydration properties. Therefore, this study was initiated.

The aim of this book is to present the latest findings in the properties and application of Supplementary Cementing Materials and blended cements currently used in the world in concrete. Sustainability is an important issue all over the world. Carbon dioxide emission has been a serious problem in the world due to the greenhouse effect. Today many countries agreed to reduce the emission of CO2. Many phases of cement and concrete technology can affect sustainability. Cement and concrete industry is responsible for the production of 7% carbon dioxide of the total world CO2 emission. The use of supplementary cementing materials (SCM), design of concrete mixtures with optimum content of cement and enhancement of concrete durability are the main issues towards sustainability in concrete industry.
