There has been a proliferation of research and development activity focused on chemically activated binder technologies and other alternative cements for use in concrete. Some activated binder technologies have been used successfully in construction or in manufacture of building products. However, a major barrier to adoption of such new materials is the lack of appropriate test methods and specifications, often precluding their use in structural applications since they are not covered by building codes. Some existing test methods may be suspect for evaluation of new cementing materials because they often do not relate well to field performance for portland cement concrete. However, engineers have experience, familiarity and a comfort level with using portland cement concrete. In addition to raising specific areas of concern with existing test methods, alternative approaches to adapting existing test methods or development of new tests specific to evaluation of chemically activated binders and alternative cements are discussed.
