Abstract: The development and uptake of new cementitious binders is always a slow process, in a
global industry which is both very large and necessarily very conservative. However, the
drivers for diversification of the world's "toolkit" of cements are growing stronger, as we
appreciate that it is not possible to meet the construction and infrastructure needs of global
society with a "one-size-fits-all" material solution, as we seek sustainable development at both
local and worldwide levels. This is fundamentally because human society is the sum (not the
average) of a very diverse set of local scenarios, each with its own particular set of needs, and
each with its own portfolio of resources. If we were to consider the average, there would
potentially be a single best option that is valid worldwide - but this is not the case, and a
technology (cement, concrete or any other material) which is sustainable and optimal in one
location will often not be appropriate in another. This leads to the absolute requirement for
development of a toolkit of cements, each of which is sustainable and fit for purpose in its
own scenario and context. This presentation will give some examples of such cements, with a
particular focus on alkali-activated binders, and will outline how innovation in materials
science research is intrinsically interlinked with innovation in use and uptake of new
