Threat-resistant glass block panel

A spacer member for maintaining substantially uniform joint spacing between construction elements during construction of a static structure comprising a plurality of construction elements bound to one another by curable matrix material. The spacer member remains embedded in and covered by the matrix material and permits the matrix material to be placed in and completely fill all construction joints between the construction elements in a single application. The spacer member includes structure located interiorly of the planes of the exposed faces of the construction elements for positively establishing and maintaining a desired position of the spacer member during construction of the structure.
