Nuclear quantum effects in cement hydration and setting
Cement and concrete are amongst the most widely used synthetic materials, yet they are also under increasing scrutiny in terms of their sustainability. Their large-scale production continues to be on the rise on a global scale, and it is currently responsible for about 10% of total anthropogenic carbon-dioxide emissions to the atmosphere. In the context above, our research efforts to date have looked at the relatively untapped possibility of achieving chemical speciation of the hydrogenous species present in these materials, using INS in combination with computational modelling. Encouraged by these results, we have also begun exploring hydration and setting phenomena, and have found strong nuclear quantum effects that merit further investigation using IN1-LAGRANGE and D1B. These experiments will give us important insights into the underlying microscopic mechanisms. And, on a more practical front, these effects can be used to tune hydration rates by adjusting the amount of light and heavy water in the primordial mix. To the best of our knowledge, this strategy represents a new means of controlling and tailoring the properties of this important class of materials.
