Hollow Glass Block Research (Project C-29). Co-operative research for the Owens-Illinois Glass Company, started in July, 1935. Investigators, R. B. Crepps (in charge) 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 walls.

 

Progress Report. 1. Modulus of rupture of mortars as influenced by alternate wetting and drying of the mortar and the mortar-bearing adhesive surface was determined

2. Substitute mortar-bearing adhesives were tested in glass block specimens subjected to the flexure test.

3. Compression tests were made on glass blocks of different sizes. These blocks had a new corrugated design for mortar bearings and different wall thicknesses.

4. Studies of plastics as sealing compounds against glass were made on a series of disc specimens.

5. Newly developed substitute expansion joint strips were tested.

6. Large glass block panels employing wood as division strips in the place of mortar are being investigated. This construction is designed for interior usage.
