A prefabricated wall panel suitable for forming interior or exterior building walls is made by a method comprising the steps:- (a) providing a flat bed mould box disposed horizontally; (b) positioning individual masonry construction units within the mould box in a predetermined pattern, each masonry construction unit being out of contact with its neighbouring unit so as to provide gaps between successive masonry construction units in the mould box; (c) pouring a fluid mortar comprising a mixture of water, a particulate rapid hardening cement comprising calcium sulfoaluminate cement, and at least one particulate bulking agent into the gaps between successive masonry construction units in the mould box and up to the level of the upper surfaces of the masonry construction units position in the mould box; (d) allowing the fluid mortar to set and cure; and then (e) removing the prefabricated wall panel from the mould box. The fluid mortar used in the method exhibits a flow diameter of at least 150mm on a horizontal surface determined according to a test procedure which comprises loading freshly prepared fluid mortar into a hollow cylindrical tube having a circular cross-section, a height of greater than 50mm and an internal diameter of 50mm, up to a height of 50mm above the bottom end of the cylindrical tube, positioning the loaded tube vertically on a horizontal surface, raising the cylindrical tube containing the fluid mortar vertically above the horizontal surface so as to allow the fluid mortar to flow out of the cylindrical tube onto the horizontal surface, allowing the fluid mortar to spread on the horizontal surface until flow ceases, and measuring the diameter of the spread of mortar on the horizontal surface.
