Hollow Glass Block Research (Project C-29). Co-operative research for the Owens-Illinois Glass Company, started in July, 1935. Investigators, R. B. Crepps and R. E. Mills.
Purpose. To study the physical and mechanical properties of hollow glass blocks as individual units and also when used for masonry panels.
Progress Report. Report No. 7, consisting of 56 pages, included results of tests on:
(1) Strength of 5-foot square panels of running bond design.
(2) Wall ties of 6 different styles for the purpose of finding the most effective type for reinforcement of glass block panels.
(3) Shear of special mortar-bearing surfaces on glass blocks.
(4) Adhesion as influenced by outside exposure during winter weather.
(5) Effect of air pressure on large Insulux masonry wall panels.
(6) Metal panel stiffener. In addition, tests are under way on panel jamb material and the effect of mortar expansion under high humidity conditions on panels 5 feet square.
These tests involve details of panel construction which will give information of considerable use in the proper design of glass block panels.
