  1. Mineral components determined using XRD. Bulk density and open porosity determined according to BS EN 772-4:1998. Pulse velocity determined in accordance with BS EN 14579:2004. Anisotropy coefficient determined according to [65]. Capillary absorption determined according to BS EN 1925:1999. Sorptivity defined as mass-percentage gained following adsorption; hysteresis as difference between mass-percentage following adsorption and desorption
