The binder-aggregate interface in NHL mortar with non-calcitic aggregate: Physical properties
Highlights Mortars made with a siliceous and a felsic (granitic) aggregate from Scotland. A wide range of aggregate content by volume with NHL5. Parallel trends in strength, sorptivity, porosity and carbonation resistance observed. The results confirm the importance of the binder-aggregate interface.
Abstract In the absence of resources of calcitic aggregates this work aimed to confirm the suitability of Scottish aggregates in NHL mortar. Strength, sorptivity, porosity and carbonation of mortars made with one siliceous and one felsic (granitic) aggregate have been studied. The results suggest that there are no technical barriers to their use and that environmental and philosophical considerations reveal positive benefits. The measured properties all depend on the relative volume proportions of binder and aggregate, even at constant water/binder ratio and the trends can be explained by considering the behaviour at the binder-aggregate interface.
