Ottoman mortars: why historical Ottoman buildings were so resistant against serious earthquakes

An interesting study published by Binici et al., in the Journal of Construction and Building Materials about the mortars (inert siliceous materials used in construction to bond brick, stone and blocks) used in historical Ottoman buildings in Erzurum province. The physico-chemical and microscopic properties of the mortars have been studied by SEM, XRD, EDS analysis. Binici et al. revealed that mortars with higher SiO2 + Al2O3 + Fe2O3 values have higher hydraulicity and cementation indices which result in higher compressive strengths. They concluded that this is the main reason why historical Ottoman buildings have been so resistant against serious earthquakes for centuries. doi:10.1016/j.conbuildmat.2010.03.013

    This is amazing. I wonder how did they find out about this without SEM, XRD etc. on those days…
